ABSTRACT:
Coating compositions contain pigment dispersants wherein the dispersant is the polymerization product of (i) an alkyl methacrylate having from 3 to 8 carbon atoms in the alkyl group, (ii) a hardening monomer selected from the group consisting of a styrene, methyl methacrylate, ethyl methacrylate and mixtures thereof, (iii) an ethylenically unsaturated carboxylic acid selected from the group consisting of acrylic acid, methacrylic acid, itaconic acid, crotonic acid, maleic acid, fumaric acid and mixtures thereof or a monomer having a double bond alpha-beta to a carbonyl group and which provides carboxyl functionality when reacted with water, alcohol, amine or anhydride, (iv) a monomer having a double bond alpha-beta to a carbonyl group and at least one hydroxyl group or a monomer which provides such groups when further reacted with an acid or an epoxide, and (v) a compound providing an amine or amine salt functional moiety. The dispersants are useful for dispersing pigments in coating compositions containing a wide variety of film-forming resins.
