    Abstract: 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.

    Abstract: A process for the conversion of a raw copper phthalocyanine into a pigmentary form by treatment of a finely divided raw copper phthalocyanine, whose crystallisation is interrupted and which is strongly agglomerated, with an organic solvent, in which the primary particle size, produced by ball-milling a raw copper phthalocyanine, is under 0.1 mu m, in which a suspension consisting of the organic solvent and the milled raw copper phthalocyanine (called a solvent-pigmentary suspension in the following) having pigment concentrations of 15 to 55% by weight and solvent concentrations of 15 to 85% by weight which can contain water from 0 to 30% by weight, is subjected to shear gradients between 1000 and 20,000 s over the course of a period of 2 to 1000 s, the energy uptake during the shearing being 0.01 to 0.2 kwh/kg of pigment put through, and in which, to discontinue formation in a defined manner, water is then metered into the solvent-pigmentary suspension in 0.1- to 10-fold the amount of the solvent and homogeneously mixed with the suspension.
