Abstract
A pigment dispersing resin which essentially consists of a modified polymer obtained by introducing at least one of acidic groups and basic groups into a polymeric polyol of star-shaped structure prepared by reacting a polyol having at least four hydroxyl groups per molecule with an epoxide, the resin being compatible with pigments and vehicle resins, and a pigment dispersed paste which comprises the pigment dispersing resin and a pigment, the pigment dispersed paste being low in viscosity over a long period of time.
