Diarylide yellow pigment compositions comprising the reaction product of tetrazotized 3,3'-dichlorobenzidine coupled into an acetoacetarylide, and, a ketimine formed by the reaction of a primary amine and an acetoacetarylide. The ketimine-containing diarylide yellow pigment compositions have improved color strength, improved transparency and contain essentially no free primary amine. Printing inks manufactured with the diarylide yellow pigment compositions of this invention have increased color strength, increased transparency, decreased degradation of publication gravure ink vehicles and decreased acidic fountain solution emulsification in offset ink printing processes.
