    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 (R1 = H, alkyl of 1 to 20 carbon atoms, unsubstituted or substituted phenyl, -C2H4-NH)zH or -(C3H6-NH)zH, z = 1, 2 or 3, and R2 = 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.
