pigmentbased

Pigmentbased is an adjective used to describe materials whose color derives from dispersed solid pigments rather than soluble dyes. The term applies across coatings, inks, plastics, cosmetics, and related products in which color depends on pigment particles embedded in a binder or matrix.

In pigmentbased systems, color arises from light scattering and absorption by finely divided particles. Pigments are typically inorganic or organic compounds that are insoluble in the medium; they are dispersed as powders and held in place by a binder. The performance of a pigmentbased formulation depends on particle size, dispersion quality, pigment loading, and binder compatibility, as well as additives such as dispersants and wetting agents. Common white, black, and color pigments include titanium dioxide, carbon black, and iron oxides, with other pigments providing a wide range of hues.

Compared with dye-based systems, pigmentbased formulations offer advantages in lightfastness, opacity, and heat resistance, but may require more complex processing to achieve uniform dispersion and color strength. Dyes tend to be brighter and more transparent but can be more sensitive to light, solvents, and environmental conditions.

Applications span architectural and automotive paints, printing inks, plastic coloration, and cosmetic powders or eyeshadows. In each field, pigment selection balances color, opacity, brightness, stability, and toxicity considerations. Historical pigment sets range from ancient mineral pigments to modern synthetic inorganic and organic pigments, reflecting advances in chemistry and materials science.
