RESIN COMPOSITION FOR PRINTING INK AND METHOD OF ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To provide a resin composition for a non-toluene type printing ink useful for coating various plastic films, plastic sheets, or a synthetic resin molding, and good in high temperature stability. SOLUTION: This printing ink contains a graft copolymer prepared by reacting an oxidation treated chlorinated polyolefin having a weight average molecular weight of 3,000-50,000 and a chlorine content of 10-50 wt.% with an acrylic monomer having an ethylenically unsaturated bond, and a mixed solvent of a polar solvent and an alicyclic solvent, and a method of its preparation.
