    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.

    Abstract: 1. A continuous process for the preparation of a poorly flowing flushed color from an aqueous pigment suspension (press cake) and a water-immiscible organic liquid which may or may not contain a binder, with the aid of an intensive mixer, wherein the aqueous pigment suspension (press cake) and the water-immiscible organic liquid (binder) or the mixture of the aqueous pigment suspension (press cake) and water-immiscible organic liquid (binder) are or is continuously fed to an intensive mixing and shearing zone, from 3 to 10% by volume of the mixture present in the said zone being subjected to a shear gradient of from 500 to 7500 S**-1 at any time and the residence time under the action of this shear gradient being from 0.5 to 60 seconds, and the remaining 97-90% by volume of the mixture are subjected to shear gradients which are lower by a factor of 10 or more, and the water phase is separated off from the water/flushed color mixture leaving the intensive mixing and shearing zone.

    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.
