    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.
