Comb pigment dispersants |
摘要 |
The polymeric pigment dispersants of this invention are polyester/acrylic comb polymers which are the reaction product of 20-85% of a carboxylic functional polyester copolymer, 10-50% of an oxirane substituted acrylic copolymer, and 2 to 20% of an imide compound. These materials disperse a wide variety of pigments and are useful in solvent borne coatings where they can provide improved efficiency of pigment use, lower paint viscosity, and reduced emission of volatile organic solvent.
