Abstract
Abstract The disclosure is of a copolymer reaction product of (A) 20 to 60 equivalent percent of a polymeric fatty acid; (B) 0 to 60 equivalent percent of a dicarboxylic acid; (C) 15 to 50 equivalent percent of a monocarboxylic acid; and (D) 5 to 25 equivalent percent of a synthetic polymeric resin having a crystalline chain structure, said resin having active carboxyl and/or hydroxyl groups capable of reaction with acid/amine groups; with (E) 50 to 80 equivalent percent of an organic polyamine. The copolymer is useful in flexographic ink compositions and such are advantageously water reducible (thinnable).
