    Abstract: A pigment formulation which comprises (a) a finely divided organic pigment and (b) one or more urea derivatives of the formula K-(NH-CO-NH-R)2, where R is C12-C18-alkyl, C12-C18-alkenyl, C8-C18-alkoxypropyl or -(CH2)3-O-(C2H4O)n-R1, R1 is C2-C8-alkyl or phenyl, n is 1, 2, 3 or 4 and K is 1,5-naphthylene or 4,4'-diphenylenemethane, with or without (c) up to 5% by weight, based on (a and b), of agents conventionally present in pigment formulations. In binder solutions, the pigment formulations give printing inks and paints possessing excellent tinctorial properties. Some of the compounds (b) prevent the conversion of alpha -copper phthalocyanine to the beta -modification.

    Abstract: Phthalocyanine formulations which comprise a mixture of (a) phthalocyanine and (b) from 2 to 20% by weight, based on (a) of one or more urea derivatives of the formula K-(-NHCO-NH-R)2 (I), where K is 1,5-naphthylene or 4,4'-diphenylenemethane, R is alkyl of 12 to 18 carbon atoms, alkenyl of 12 to 18 carbon atoms, 3-(alkoxy of 8 to 18 carbon atoms)-propyl, 2-(alkylamino of 8 to 18 carbon atoms)-ethyl or (CH2)3-O-(CH2-CH2O)n-R1, R1 is alkyl of 2 to 8 carbon atoms or phenyl and n is 1, 2, 3 or 4, and which are obtained by milling (a) with (b) in the absence of a grinding medium. When used in printing inks, such as offset printing inks, the formulations give deeply colored prints in very pure hues, with very low graininess of the ink.
