Abstract

Pigments, unlike dyes, are insoluble in their application medium. Although similar in chemical composition, pigments differ from dyes in that they are applied in the solid state and thus their physical characteristics such as crystal lattice arrangement, unit cell geometry and particle characteristics, including size, shape, specific surface area, and surface structure, are of critical importance in determining their application properties. The increasing demands being placed on coloring materials means that the technical requirements for pigments are now extremely varied. The applications of pigments include decorative and industrial paint systems, plastics, and printing inks for substrates such as textiles. To develop pigments for use in new vehicle systems, two broad strategies may be used. The first is the development of new pigment types and the second is the optimization of existing products by modification of their physical characteristics, such as particle size and surface characteristics.
