Abstract

A dispersing resin for conventional solventborne pigment preparations having a low to very low proportion of volatile organic substances is provided. Further provided are solventborne coating materials containing the dispersing resin. Uses include paints, varnishes, adhesives, inks or printing inks, and compositions for coloring of plastics. The pigment preparations produced with these resins are free of yellowing, stable to weathering, of low viscosity and intensely colored.
