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).sub.2, where K is 1,5-naphthylene or 4,4'-diphenylenemethane and R is C.sub.12 -C.sub.18 -alkyl, C.sub.12 -C.sub.18 -alkenyl, C.sub.8 -C.sub.18 -alkoxypropyl or C.sub.2 -C.sub.8 -alkoxyethyleneoxypropyl, (e) a C.sub.6 -C.sub.18 -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.

Abstract: Stable, fluid formulations contain (a) finely divided iron cyano complexes, iron-III oxides or iron-III oxide hydrates, (b) one or more C.sub.6 -C.sub.18 -alkylbenzenesulfonic acid, (c) one or more compounds which are obtained by Mannich condensation from 2-hydroxynaphthalene, which may or may not contain 1 or 2 additional .beta.-hydroxyl groups, formaldehyde and primary or secondary aliphatic, cycloaliphatic or aromatic monoamines, diamines, triamines or polyamines or 5- or 6-membered heterocyclic compounds, and which contain from 1 to 6 .beta.-hydroxynaphthyl groups, and (d) one or more organic liquids, the ratio of (b):(c) being from 1:8 to 2:1 and the amount of (c) being from 10 to 20% by weight, based on (a).The formulations are fluid or pourable at pigment concentrations of from 20 to 55% by weight and give very deeply colored, very glossy finishes.

Abstract: A stable fluid formulation which comprises (a) finely divided .alpha.- or .beta.-copper phthalocyanines or finely divided indanthrone, one or more C.sub.6 -C.sub.18 -alkylbenzenesulfonic acids (b), a basic copper phthalocyanine (c) of the formula ##STR1## where CuPc is an n-valent copper phthalocyanine radical, R.sup.1 and R.sup.2 independently of one another are H or C.sub.1 -C.sub.8 -alkyl and n is 1, 2, 3 or 4, one or more compounds (d) which are obtained by Mannich condensation of 2-hydroxy-naphthalene, which may or may not contain 1 or 2 additional .beta.-hydroxyl groups, formaldehyde and primary or secondary aliphatic, cycloaliphatic or aromatic monoamines, diamines, triamines or polyamines or 5-membered or 6-membered heterocyclic compounds which contain an >NH-- group as a ring member and which contain from 1 to 6 .beta.-hydroxynaphthyl groups, and one or more organic liquids (e). The weight ratio (b):(c):(d) is from 1:1:1 to 2.5:1.25:1.
