Abstract

A method for preparing a resinous pigment composition is disclosed which method includes charging pigment, water and water-insoluble resin which is solid at room temperature into a mill containing a dispersing medium and milling the charge at a temperature below the softening point of the resin to reduce the pigment to a fine powder and to disperse it uniformly throughout the resin.
