Abstract
The disclosure is of a copolymer reaction product of PA1 (A) 20 to 60 equivalent percent of a polymeric fatty acid; PA1 (B) 0 to 60 equivalent percent of a dicarboxylic acid; PA1 (C) 15 to 50 equivalent percent of a monocarboxylic acid; and PA1 (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 PA1 (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).
