Pigment formulation, a process for its preparation, and its use

摘要

The invention relates to readily dispersible strong pigment formulations containing arylpararosanilinesulfonic acid pigments of the formula <IMAGE> 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.
