Abstract
Abstract A pigment composition, suitable for use in modern offset and letter press inks, comprising: (A) (a) a pigment derived from (i) acetoacet-2,4-xylidide coupled on to tetrazotized 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 tetrazotized 3,3'-dichlorobenzidine; (b) a dyestuff derived from coupling acetoacetanilide, acetoacet-2-toluidide, acetoacet-2-chloranilide or acetoacet-2,4-xylidide on to tetrazotized 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-toluidide, acetoacet-4-toluidide, acetoacet-2-chloranilide, acetoacet-2,4-xylidide and acetoacet-2,5-dimethoxy-4-chloranilide on to one or both of tetrazotized 3,3'-dichlorobenzidine and tetrazotized 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.
