  2. Color Perception and Color Quality of White LED Light Sources

    Sebastian Babilon, M.Sc. | M. Sc. of Laboratory of Lighting Technology, Technical University of Darmstadt

    For many lighting applications (e.g., home and office lighting, museum lighting, in the shopping and retail industry,…), the goal of achieving a high user acceptability and visual appreciation should be in first place when developing new state-of-the-art lighting solutions. However, such a real life optimization problem can only be solved satisfyingly when suitable tools and algorithms are available for developers and manufacturers that are capable of adequately modeling the visual perception of human beings. Besides giving an overview of the latest LED technology including the proper application of coating materials for high-quality white light emission, the main focus of the current talk should therefore be on the scientific innovations of assessing the color quality of such light sources. In addition to the latest fidelity-based color quality metrics such as  or TM 30-15 intended to replace the outdated but still widely used CIE  metric, the best overall performance when it comes to the more subjective aspects of color perception can be observed for color quality metrics that are based on internal references such as preferred or memory colors, especially in lighting applications where the achievement of high observer preference is more important than color fidelity. Based on recent scientific findings, a selection of such metrics will be presented with their predictive performances being validated on experimental data in order to finally come up with a recommendation for the optimization of white LED light sources and luminaires in terms of visual appreciation and observer preference.

Chair: Dr. Andrew E. Smith, Product Engineering Manager, Uniform Color Company, USA

  1. Staying Relevant: Aligning Color, Material, and Finish Solutions in Plastics with Global Megatrends

    Theresa Patton | Marketing Development Manager for Color Americas of PolyOne

    Leverage global megatrends to develop color, material and finish solutions in polymer that resonate with emerging and longer-term societal trends.  

    Explore evolution as it pertains to design, as consumers respond to shifts – in the economy, in politics, and especially in culture. When it comes to color’s role in this evolution, it’s clear that trends based on deep-rooted societal changes have greater authenticity and staying power than more ephemeral fads.

    Color Inspirations 2019+ examines the once and future progression of art and design, beginning with minerals of the Stone Age and hand-made art of indigenous cultures. It detours for a look at the sometimes-unnerving techno natural aesthetic of today, and investigates the ways that our shared heritage will leave its mark on upcoming color, material and finish preferences.

    Color Inspirations 2019+ goes well beyond color by capturing the zeitgeist of the moment through innovative special effects, finishes and material solutions that support these ideas.

  2. Soft Focus, Optical Blur, and the Pigments That Cause Them

    Jonathan Doll, Ph. D. | Leader – Effect Pigments of Sun Chemical Corporation

    The soft focus effect has traditionally been achieved in photography by using lenses with a spherical aberration.  As defined, soft focus gives a blurred image while retaining sharp edges, almost like a glow.  More recently, soft focus has been identified as a desirable effect in cosmetic and personal care applications as a means to obscure blemishes and wrinkles on the skin while maintaining a natural look.  While this seems like a straightforward definition, there are few pigments exhibiting the soft focus effect.  In this presentation, a method to measure soft focus will be presented and a new soft focus pigment system will be presented.  The use of this pigment in applications ranging from cosmetics to coating and plastics will be discussed.

Session IV: Advancements in Pigment Technology

This session will provide overviews on advancements in effect and expand pigments.


Chair: Bill Eibon, Director, Technology Acquisition, PPG Industries, USA

  1. Utilizing Multiple Light Scattering For Quantitative Stability Analysis of Concentrated Pigment Dispersions

    Matt Vanden Eynden, Ph.D. | Analytical Chemist of Formulaction, Inc.

    Pigment dispersion possess inherent stability issues, typically in regards to sedimentation and packing of the particles in the suspension. Issues related to raw material control, ingredient regulations, new formulation development, and shelf life stability all result in the need for a quantitative technique to monitor and predict the stability of such dispersions. Here, we will show how Multiple Light Scattering can be used to quantify physical destabilization phenomena such as sedimentation, clarification, and flocculation all without sample preparation or dilution. This technique allows for facile modification of the mixtures to fit a stability profile as ingredients change.

  2. On The Road to new Dimensions in the Golden to Red Color Space

    Co-Presented by Raimund Schmid & Javier Marcillo Ruiz of BASF Colors & Effects GmbH

    The world of automotive coatings is strongly driven by color design and increasing technological requirements. Color designers typically are desiring new pigments which allow access to hitherto unknown colors and effects while the technology departments of automotive coatings manufacturers ongoingly improve appearance, fastness and especially hiding of basecoats.

    R&D in the field of effect pigments is still in a stage where huge performance improvements from one generation to the next one are possible. Iron oxide coated aluminum flakes are known since more than 25 years for high chroma in golden, orange and red colors in combination with excellent hiding and gloss. The latest generation of iron oxide coated, thin silver dollars was now complemented with Paliocrom® Brilliant Red and Paliocrom® Premium Gold. The latter is compared to the first golden generation almost doubled in chroma.

    In the field of classical absorption pigments usually existing chromophores are being improved through modifications of pigment crystal shapes and -surface treatments. Since new chromophores are rare, the improvements of absorption pigments had so far typically a more incremental character. Basically the answer to the questions from all industrial segments “How to increase chroma and transparency ?” is, if answered by a physist is easy → Smaller particles will allow to reduce scattering and increase chroma and transparency. To make this happen within an industrial process is on a level full of complexity and controversy answers.

    That has changed with the latest developed answer, the exciting of eXpand!™ Red EH 3427 – a pioneering stir-in pigment for automotive coatings.  The styling options with the first stir-in pigment for automotive coatings become infinite in combination with effect pigments, such as Premium Gold. For color designers the trip to new dimensions in the golden to red color space can start…

    Delegates are invited to visit the exhibit area at this time.

  4. Highly targeted color spaces with made-to-measure Iron Oxide Pigments

    Carsten Rosenhahn | Vice President, Product & Business Development, Business Unit Inorganic Pigments of LANXESS Deutschland GmbH

    Approximately 1 million tons of iron oxide are processed per year as colorants in the coatings, plastics, and construction industries. Despite their long history as coloring agents and major manufacturing breakthroughs within the last century, the coloristic potentials of iron oxides have not been fully exploited, to date. Recent innovations focus on expansion of the current iron oxide red color range to include pigments of higher chroma than those currently available in the market.

    The chromaticity of inorganic pigments is determined by the complex relationship between particle size and shape, dopants, particle size distribution and dispersibility within the matrix material. A novel production procedure is presented which yields particles of uniform size distribution, whereby the color can be precisely adjusted by targeted parameter control. Superior colors are achieved by individually tuning the influencing variables during synthesis and processing. The pigments obtained exceed the current coloristic limitations of iron oxide red pigments.

  5. Advanced Solutions for Transparent Iron Oxide Pigment Dispersions in Waterborne Concentrates

    Loulou Rozek | Global Technical Service Manager of Borchers Americas, Inc.

    Transparent iron oxide pigments produce a depth of shade that is perceived as rich and prestigious among consumers. Due to their coloristic performance, UV resistance and high transparency nature, these pigments found strong applications in wood and automotive coatings.

    One of the big challenges paint formulators face when working with transparent iron oxide pigments is their poor surface wetting properties in aqueous systems, leading to long grind times, high viscosity and lower than desired transparency. As a result, these pigments found limited usage in the rapidly growing waterborne wood and automotive coatings. This paper will discuss why these pigments are so appealing yet difficult to disperse and how to overcome these challenges using unique pigment wetting technology based on polyurethane chemistry engineered with a combination of different anchoring groups specifically designed and positioned to provide fast and strong interactions with the surface of these pigments.

    Four leading grades of red and yellow transparent iron oxide pigments are evaluated using several stabilizing technologies to demonstrate the correlation between the particle size distribution of the grinds and its impact on transparency, viscosity and stability of the dispersion.

    Additionally, a method for quantifying transparency is demonstrated using 1k and 2k acrylic binder systems where dE* between absolute black and coated black is measured using two spectrometric techniques.

    Producing and applying high performance waterborne transparent iron oxide pigment dispersions is now possible and easier than ever before.

Session V: Advancements in Pigment Technology (continued)

This session will provide overviews on advancements in effect and expand pigments


Chair: Professor Gerhard Pflaff, Director of Pigment Research, Merck

  1. Progress in new Ultra-Thin Effect Pigments

    Adalbert Huber | Vice President R&D of Schlenk Metallic Pigments GmbH

    After successful introduction of the first ultra-thin effect pigment, a golden pigment, research has been focused on additional colors. The color gamut of this novel technology will be extended. This gives the color designers new possibilities to develop different golden color shades with the same key advantages like outstanding hiding power, unreached down-flop and safe use of these pigments.

  2. Development of Standards for Flake Effect Pigments

    Ian Campbell | Senior Scientist of Lucideon

    Lucideon has a long standing connection with the ceramic and related industries and has developed their widely used CCSII Set of ceramic Colour Standards.  More recently, client requests have led to the investigation and development of special Artefacts - including flake effect standards with similar durability - initially for users of goniospectrophotometers in the automotive sector.

    In this presentation, Ian Campbell describes the work involved in the preparation of ceramic Colour Standards and the process that led to the successful development of a flake effect Standard Artefact.

  3. Overcoming the challenges of coloring engineering polymers

    Douglas Koerner | Global Market Manager, Plastic Colorants, Plastic Additives of Milliken & Company

    As high impact plastics continue to replace steel, aluminum and other metals for the purpose of light weighting, there has been a recent shift toward the use more high performance, high heat engineering polymers, such as polyamide, polysulfone, PEEK and PPO. However, most traditional dyes are unsuitable for use in these plastics due to extremely high processing and service temperatures, exposure to artificial and natural light sources, exposure to outside forces, additives compatibility and physical properties maintenance. Join Doug Koerner as he shares current market trends and explains how to overcome the challenges of coloring engineering polymers.

Co-Chair:  Bill Eibon | Director, Technology Acquisition | PPG, USA

  1. Learning from Nature to Design Structural Colors

    Ali Dhinojwala | Chair Professor of Polymer Science of The University of Akron

    Melanin is one of the most important pigments used by birds in producing iridescent colors. It has a high refractive index and a broad absorption in the visible spectral range. The periodic spacing between melanin particles leads to structural colors that have high saturation and contrast. Based on this knowledge we have synthesized melanin particles starting with dopamine monomers and using self-assembly to produce structural colors. The control of spacing between particles can be tuned to obtain tunable colors over the whole visible spectral range. The simple one-pot process used for self assembly makes it an economical process for producing structural colors.

  2. What Birds have Taught us about Structural Color

    Prof. Vinothan N. Manoharan | Wagner Family Professor of Chemical Engineering and Professor of Physics of Harvard University

    Most colored materials owe their color to the absorption of light: certain wavelengths are absorbed and others transmitted. The color arises from the remaining wavelengths that are reflected or scattered back to the observer. In nature we often see a different type of coloration, known as structural color, which comes from interference or diffraction of light and not absorption: certain wavelengths are transmitted, while others constructively interfere and are reflected. Structural colors are common in birds and particularly in blue feathers, which consist of disordered arrays of pores that scatter light.  I will discuss efforts to make synthetic systems that mimic the bird feathers -- that is, systems that show structural colors that are indistinguishable from traditional, absorption-based colors, both in their saturation and their angle independence.

  3. Crystalline Colloidal Array Pigments

    Eldon Decker | Research Associate of PPG

    A new, all polymeric class of effect pigments has been developed and demonstrated. These pigments rely on the same physics as x-ray diffraction from a crystalline lattice, namely, Bragg diffraction. However, instead of x-rays being diffracted from a lattice of atoms, ultra-violet, visible, and near-infrared light can be diffracted from nano-structured, periodic arrays of polymer spheres. Control of the refractive index and arrangement of the polymer spheres can produce a variety of colors and color effects. A patent portfolio of unique, esthetically pleasing color from all-polymer crystalline colloidal array (CCA) technology has been developed.

Session VII: Advancements in Color Science

Chair:  Dr. Andrew E. Smith | Product Engineering Manager | Uniform Color Company, USA

  1. Recent Advances in Colormatching of Colors with Effects

    Dr. Guillaume Turpin | CEO of Seelab

    For solid colors, colormatching systems exists for several decades. They are composed of a spectrophotocolorimeter (d/8 or 45:0) and a combinatorial algorithm (ex. : Kubelka-Munk). For colors with effects, containing metallic and pearlescent pigments, no efficient widely-diffused commercial system exists. New Seelab system is composed of a goniospectrophotometer, called GP150, and of a dedicated software, called GX Effect. Fast BRDF measurement of single components (solid, metallic, and pearlescent pigments) are performed to create the database. Then, flashing a sample to match, mixing BRDF modelization software operates, to identify formulas. On that basis, recent advances are shown.

Session VIII: Advancements in End-Use Applications (Plenary Session)

A joint session of the Pigment and Color Science Forum & TiO2 World Summit


Moderator:   Ken Walker | Senior Staff Scientist | Sherwin-Williams Company

  1. The Future of transportation mobility and its effect on coatings, color, and pigments

    Dr. Christopher Seubert | Research Engineer of Ford Research and Innovation Center

    Significant change is coming to the automotive industry due to the introduction of both autonomous vehicles (AVs) and potentially new vehicle ownership models.  Initially, AVs will be owned by companies that specialize in moving people and goods, in order to maximize the number of hours these expensive vehicles are in use. Shorter vehicle lifetimes may result from these duty cycles, which may impact coating performance requirements.  In addition, declining personal ownership may discount the value of color as more vehicles are branded for fleet use.  A decline in vehicle collisions will negatively affect the refinish coatings market.  New functionality in coatings to improve visibility to LIDAR and increase sensor robustness are opportunities for coatings and pigment suppliers.

  2. Advancements in Aerospace Coatings and Future Material Needs

    Karen Schultz | Materials Engineer of Boeing Research & Technology

    Exterior commercial airplane coating systems serve both decorative and protective functions, and therefore need to retain color and gloss, as well as corrosion and fluid resistance, when exposed to harsh operating environments. There are strong economic and environmental drivers to improve current exterior coating systems by extending their useful life from about 4 years to 10+ years. Enhanced functionality, such as reduced drag or increased dirt, bug, and ice resistance, is also desired. In order to reach the goal of superior aerospace coatings, there is a continued need for improved pigments, additives, and resin systems that will exceed current durability and performance expectations, as well as increase manufacturing and maintenance efficiency.
