The Commonly Used Pigment Yellow 13 In The Printing Inks

Pigment Yellow 13 is a widely used yellow organic pigment and an azo compound, derived from 3,3'-dichlorobenzidine. It is also classified as a diarylide pigment and closely related to Pigment Yellow 12, wherein the two xylyl groups are replaced by phenyl. P.Y.13 and its chemically modified derivatives, due to their higher solvent fastness compared to P.Y.12, are used in much greater volume in packaging gravure inks.
