Benzidine yellow pigments are a class of classic azo-based organic yellow pigments. They get their name because their early synthesis process is related to benzidine derivatives. Widely used in fields such as inks, plastics, and coatings, they are among the most important yellow pigments in industrial coloring.
According to differences in hue and performance, common types include:
P.Y.12 (Benzidine Yellow G): It is a greenish yellow with bright color and strong tinting strength, and is one of the most widely used types.
P.Y.13 (Benzidine Yellow GR): It is a bluish yellow, with better heat resistance and solvent resistance, suitable for high-demand scenarios.
Other derivative types: Such as P.Y.14 (reddish yellow), P.Y.17, etc., which have slightly different hues and performances to meet different needs.
