Zusammenfassung:	Pigment Compositions based on Acetoacetarylide Derivatives A pigment composition, suitable for use in modern offset and letter press inks, comprising: A) a) a pigment derived from i) acetoscet-2,4-xylidide coupled on to tetrazotised 3,3'-dichlorobenzidine or from ii) the mixed coupling of two or more of acetoacetanilide, acetoacet-2-anisidide, acetoacet-2-toluidide, acetoacet-2-chloranilide, acetoacet-2,4-xylidide and acetoacet-2,5-dimethoxy-4-chloranilide on to tetrazotised 3,3'dichlorobenzidine; b) a dyestuff derived from coupling acetoacetanilide, acetoacet-2-toluidide, acetoscet-2-chloranilide or acetoacet-2,4-xylidide on to tetrazotised benzidine-2,2'-disulfonic acid; and optionally c) a resin or resinous material and B) a) a pigment derived from coupling one or more of acetoacetanilide, acetoacet-2-anisidide, acetoacet-2-toluldide, acetoacet-4-tolu-idide, acetoacet-2-chloranilide, acetoacet-2,4-xylidide and acetoacet-2,5-dimethoxy-4-chloranilide on to one or both of tetrazotised 3,3'-dichlorobenzidine and tetrazotised 3,3'dimethoxybenzidine; and b) an aliphatic amine, the ratio of components A) and B) in the pigment composition of the invention ranging from 35:65 to 95:5 % by weight.
