| titleOfInvention | A polymeric pigment dispersant having an acrylic backbone, polyester side chains, cyclic imide groups and quaternary ammonium groups |
| abstract | A polymeric pigment dispersant of a graft polymer having an acrylic polymer backbone and pending from the backbone, polyester side chains, cyclic imide groups and quaternary ammonium groups and the polymer having a calculated number average molecular weight of 8,000-50,000; wherein the graft copolymer is composed of: (a)10-50 %, by weight of the graft polymer, of an acrylic copolymer backbone having a number average molecular weight of 2,500-10,000 which, before reaction, contains 25-75 % by weight of polymerized oxirane containing monomers; (b) 20-85 %, by weight of the graft polymer, of a polyester copolymer, or mixture of different polyester copolymers, having a number average molecular weight of 500-10,000 which polyester copolymer is carboxylic acid functional and is attached to the backbone by a reaction of the carboxylic acid functional group with oxirane group of the backbone; (c) 1- 16 %, by weight of the graft polymer, of cyclic imide groups attached to the backbone by a reaction of the imide group with the oxirane group of the backbone and (d) 0.2-17 %, by weight of the graft polymer, of quaternary ammonium groups. |
