摘要:
Water-soluble or water-dispersible addition copolymer of ethylenically unsaturated monomers, wherein the ethylenically unsaturated monomers comprise N-vinyl-2-pyrrolidinone and ethylenically unsaturated polyether, is useful as a component of inkjet printable coatings. The copolymer serves to reduce later migration of inks printed on the coatings.
