Abstract

PURPOSE: To obtain an azo pigment with excellent storage stability, luster and fluidity, by incorporating an acetoacetanilide-base monoazo pigment in a benzidinebase disazo pigment during coupling or after separately synthesized.
CONSTITUTION: 1W20mol of acetoacetanilide-base monoazo pigment of formula II (wherein R4, R5 and R6 are each H, alkyl, alkoxy, nitro or a halogen atom) is incorporated in a benzidine-base disazo pigment of formulaI(wherein X1 and X2 are each H, Cl, methyl or methoxy; R1, R2 and R3 are each H, alkyl, alkoxy or a halogen atom; X1 and X2 are not simultaneously H together) during coupling or after separately synthesized. A benzidine deriv. as the base component for the benzidine-base disazo pigment of formulaIis 3,3'-dichlorobenzidine, 3,3'- dimethoxybenzidine, etc. The acetoacetanilide deriv. as a coupler component is acetoaceto-O-chloroanilide, acetoaceto-O-toluidide, etc.
