This invention relates to substituted azophthalocyanine pigment precursors which produce uniform mixed colors when their solubilising groups are eliminated. These compounds are of formulam, n and p are each independently of one another 0 or 1,R1, R2, R3 and R4 are each independently of one another a group of formulaR5 is C1-C12alkyl, C1-C12alkoxy, cyano orR6, R7 and Rq are H, E5, C1-C12alkyl,R8 is H, halogen, C1-C12alkyl or C1-C12alkoxy,R10, R11, R12, R13 and R14 are each independently of one another H, C1-C12alkyl, C1-C12-alkoxy, trifluoromethyl, nitro, halogen orR15 is C1-C12alkyl, or C6-C10aryl which is unsubstituted or substituted by 1 to 3 substituents selected from the group consisting of C1-C12alkyl, C1-C12alkoxy, trifluoromethyl, nitro and halogen,M is two hydrogen atoms or a divalent metal, oxometal, halogenometal or hydroxymetal, where the divalent metal may be additionally coordinated at one or two identical or different neutral ligands, andE1, E2, E3, E4, E5, E6 and E7 are each independently of one another hydrogen or a group of formula where at least one group E1, E2, E3, E4, E5, E6 or E7 in a group R1, R2, R3 or R4 is not hydrogen, and L is any group suitable for solubilizing.
