  • Pigment dispersing additive for coating compositions
    Patent number: 5585427
    Abstract: A copolymer with an acid value less than one contains alternating units of a vinyl monomer and a diester of a dicarboxylic acid wherein at least one of the esterifying groups contains a polyether group. The copolymer is particularly useful in preparing pigment dispersions for coating compositions. Such compositions exhibit properties including reduced pigment settling and improved metallic flake orientation, flow and leveling.
