Definition and Applications of Organic Pigments
Organic pigments are a class of insoluble coloring agents composed primarily of organic compounds. They are typically incorporated into substrates in a highly dispersed state to achieve coloring. The key distinction between organic pigments and dyes lies in the fact that organic pigments are insoluble in both the application medium and the substrate being colored.
