Abstract

Pigment preparations obtainable by coating an organic pigment suspended in an aqueous medium with a resin having an acid number of .gtoreq.200 and with a nonionic surfactant, and isolating and optionally drying and mechanically comminuting the coated pigment, are useful for pigmenting water-thinnable printing inks and coatings.
