Readily dispersible formulations comprising (a) finely divided copper phthalocyanine and (b) an iron hexacyanoferrate-III pigment are obtained by thoroughly milling a mixture of (a) and (b). The performance characteristics and tinctorial properties of the formulations comprising (a) and (b) can be improved by incorporating (c) a Mannich condensate obtained from 2-hydroxynaphthalene which may or may not possess 1 or 2 further beta -OH groups, formaldehyde and a primary or secondary amine, (d) a compound of the formula K(-NH-CONH-R)2, where K is 1,5-naphthylene or 4,4'-diphenylenemethane and R is C12-C18-alkyl, C12-C18-alkenyl, C8-C18-alkoxypropyl or C2-C8-alkoxyethyleneoxypropyl, (e) a C6-C18-alkylbenzenesulfonic acid and (f) a mixture of (e) with a basic copper phthalocyanine and/or a salt obtained by reacting (e) with the basic copper phthalocyanine. The finishes and printing inks produced using the formulations have tinctorial properties and performance characteristics which are superior to those of finishes and inks obtained by mixing individually milled or dispersed components. |
