ABSTRACT:
A phthalocyanine formulation which is stabilized against recrystallization and change of modification and which contains, as the stabilizer (a) a finely divided phthalocyanine as the pigment and (b) a salt or the corresponding homogeneous mixture of (.alpha.) a phthalocyanine derivative, which carries basic groups ##STR1## (R.sup.1 = H, alkyl of 1 to 20 carbon atoms, unsubstituted or substituted phenyl, --C.sub.2 H.sub.4 --NH).sub.z H or --(C.sub.3 H.sub.6 --NH).sub.z H, z = 1, 2 or 3, and R.sup.2 = H, alkyl of 1 to 6 carbon atoms or cycloalkyl of 6 to 8 carbon atoms) and (.beta.) an aliphatic sulfonic acid of 8 to 20 carbon atoms, a monoalkylbenzenesulfonic acid or dialkylbenzenesulfonic acid where alkyl is of 6 to 20 carbon atoms, or a monoalkylnaphthalenesulfonic acid or dialkylnaphthalenesulfonic acid where alkyl is of 6 to 20 carbon atoms, which acids may be substituted by hydroxyl, the molar ratio of .alpha.:.beta. being from 1:1 to 1:5, and, if desired, one or more organic fluids or solutions of resins in these fluids. The formulations are stable even in aromatic hydrocarbons and produce pure, deep colorations which have high gloss.
