Novel formulations which contain (a) one or more azo pigments based on coupling products of aromatic monoamines or 4,4'-diaminodiphenyls with acetoacetarylides, 1-arylpyrazolones, 3-hydroxy-2-naphthoic acid derivatives or beta -naphthol and (b) one or more dyes of the formula Q-(X)n where F is an n-valent radical of a monoazo dye, of a disazo dye or of a quinophthalone, n is 1, 2, 3 or 4 and X is a group of the formula <IMAGE> where R1 and R2 are each hydrogen or C1-C4-alkyl, R3 is C1-C4-alkyl or hydroxy-C2-C4-alkyl and A(-) is one equivalent of an anion. The pigments present in the formulations exhibit improved tinctorial, rheological and printing properties when the formulations are used in printing inks. |
