Abstract

The invention relates to readily dispersible strong pigment formulations containing arylpararosanilinesulfonic acid pigments of the formula ##STR1## and a polyester resin which has been water-solubilized by neutralizing the carboxyl groups with nitrogen bases. The pigment formulations are distinguished by being very readily dispersible in the various printing ink binders and by having a high tinctorial strength.
