Phthalocyanine formulations having high gloss, which are stabilized against recrystallization and against change of modification

A finely divided solid to pasty phthalocyanine formulation which is stable against recrystallization and change of modification, which gives colorations having good gloss, and which consists essentially of

• a. a finely divided phthalocyanine dispersed in insoluble form as the pigment and (b) from 10 to 40 percent by weight, based on (a), of a salt or the corresponding homogeneous mixture, also dispersed in insoluble form, of
• (.alpha.) one or more phthalocyanine derivatives of the formula ##STR39## where Pc is an n-valent radical of the metal-free phthalocyanine, of a copper phthalocyanine or of a mixture of these, X is --CH.sub.2 --, ##STR40## --CH.sub.2 --CH.sub.2 --COO--C.sub.2 H.sub.4 -- or --CH.sub.2 --CH.sub.2 --COO--C.sub.3 H.sub.6 --, R.sup.1 is hydrogen, alkyl of 1 to 20 carbon atoms, phenyl, phenyl which is substituted by methyl, methoxy, ethoxy or chlorine, --(C.sub.2 H.sub.4 --NH).sub.z H or --(C.sub.3 H.sub.6 --NH).sub.z H, R.sup.2 is hydrogen, alkyl of 1 to 6 carbon atoms or cycloalkyl of 6 to 8 carbon atoms, alk is linear or branched saturated alkylene of 2 to 6 carbon atoms, R is hydrogen or alkyl of 1 to 4 carbon atoms, and R and R.sup.2 may be linked to one another, n is a number from 2 to 5, z is an integer from 1 to 3 and the group ##STR41## may also be a heterocyclic ring selected from the group consisting of morpholinyl, thiomorpholinyl, piperazinyl, N-methylpiperazinyl, N-ethylpiperazinyl, piperidinyl, pyrrolidinyl and ##STR42## and (.beta.) a saturated or unsaturated aliphatic sulfonic acid of 8 to 20 carbon atoms, a benzenesulfonic or naphthalenesulfonic acid, substituted by one or two alkyl groups each of 6 to 20 carbon atoms, and in which the benzene or naphthalene nucleus can be substituted by a hydroxyl group, or mixtures thereof, the molar ratio of (.alpha.) :
• (.beta.) being from 1:1 to 1:5, and the said salt or corresponding mixture acting as a stabilizer in the formulation.
