Abstract
Novel graft copolymers of shellac and a polyalkyleneglycol monomethacrylate are prepared. These graft copolymers are useful in preparing water-based flexographic, i.e. packaging laminating inks, comprised of a pigment; the graft copolymer; a binder resin; an alkanol; an alkali, ammonia or an amine; and water.
