    摘要： Triaminotriphenylmethane pigments are prepared by a) first reacting an iron, boron or aluminum trihalide complex compound of a 4,4',4"-trihalotriphenylmethane halide with a salt of an aromatic aminosulfonic acid in a molar ratio of 0.6:1 to 1.4:1 at a temperature between 130.degree. and 180.degree. C., under hydrogen halide partial pressure of at least 1 bar and in the presence of a polar, water-insoluble organic solvent, subsequently b) reacting the reaction suspension obtained according to a) with at least 5 molar equivalents of an aromatic amine subsequently c) either bringing the amine melt obtained according to b), in the absence of a water-soluble solvent, to a pH of between 1 and 6 by addition of a mineral acid or first bringing it to a pH of at least 9 with an alkali metal hydroxide solution in the presence of a viscosity-lowering additive, carrying out a phase separation, adding a water-insoluble organic solvent to the organic phase and then bringing this to a pH of between 1 and 6 by addition of a mineral acid. The pigments obtained can be processed into high-quality printing inks.

    摘要： The invention relates to a pigment composition based on P.Y. 191 of the formula (1) containing 0.05 to 30 mol %, based on the sum of P.Y. 191 and a further yellow colorant, of at least one further yellow colorant of the formula (2) and/or of C.I. Pigment Yellow 100 in which R1, R2, R3 and R4 are each independently hydrogen, halogen, —CH3, —NO2, or NH—R6 where R6 is C1-C4-alkyl; R5 is methyl or carboxyl, and where the compound of the formula (2) is not C.I. Pigment Yellow 191.
