CA 2188548

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.

Les dispersants de pigments polymères selon cette invention sont des polymères polyester/acryliques à structure en peigne qui sont le produit de la réaction entre 20 à 85 % d'un copolymère polyester à fonctionnalité carboxylique, 10 à 50 % d'un copolymère acrylique substitué par oxirane, et 2 à 20 % d'un composé imide. Ces matériaux dispersent une grande variété de pigments et peuvent être utilisés dans des revêtements à base de solvant auxquels ils confèrent une efficacité d'utilisation de pigment améliorée, une viscosité de peinture inférieure et des émissions réduites de solvants organiques volatils.
