All color phenomena that we can observe in coatings have their origin in the interaction between the coating material and visible light. This interaction produces absorption and scattering, which in practice determine the optical behavior of materials.

This completely revised second edition of Industrial Color Testing: Fundamentals and Techniques offers a thorough treatment of the field, focusing on the practical and theoretical aspects of testing pigments, dyes, and pigmented and dyed coatings. It provides broad descriptions of the underlying principles, which will be of especial benefit to newcomers to the field; moreover, its in-depth treatment makes it an ideal reference for experts, answering questions arising in the production, processing, and application of coloring materials in binders.

From the Preface: “...It is often not enough to be familiar with the procedure used in a test; more must be known about the quantity being measured and the way in which it varies as a function of other parameters — in brief, about its physicochemical habit, which is embedded in the well-known fields of chemistry and physics. This is especially important when test methods are to be rationalized; rationalization requires computers, and all computer use is based on applied mathematics. Effective rationalization is possible only when the mathematical and physical background of the quantitites being measured is kept fully in view. The lack of suitable worked-out examples to illustrate test methods often creates difficulties in practice as well. This book should help close the gap by providing at least one practical example for each of the test methods described...”

Target Audience: All technical personnel involved with coatings, pigments and dyes, whether as manufacturers, converters, or consumers, including engineers in industry, research scientists, educators and students.
