Abstract
The present invention provides a process for producing a durable, external surfactant free, cationic, water based jet ink polymer which when formulated into an ink, coating or film that results in a excellent adhesion to metal or plastic substrates. The hybridized copolymer comprises a hydrophobic functional polymeric backbone comprising a functional vinylchloride-containing polymer portion having an average molecular weight of from 15,000 to 200,000 g/mole and at least one polymer portion selected from the group consisting of a functional polyolefin and a functional polysiloxane. The hybridized copolymer also comprises a plurality of copolymeric side chains attached to the backbone, comprising a polymerizable amine-containing unsaturated monomer, and a polymerizable unsaturated monomer.
