<P>PROBLEM TO BE SOLVED: To provide a resin for an aqueous ink for printing on films, which is intended for obtaining the aqueous ink for printing on films having improved characteristics such as scratch resistance, water resistance, shelf stability and adhesion to a substrate film compared to conventional ones, and a resin composition for the aqueous ink for printing on films. <P>SOLUTION: The resin for the aqueous ink for printing on films comprises a copolymer obtained by polymerizing a monomer mixture comprising 5-40 wt.% (acrylonitrile and/or methacrylonitrile), 95-40 wt.% ethyl acrylate and 0-20 wt.% monomer copolymerizable with these in the presence of a surfactant mixture comprising a nonionic surfactant and an anionic surfactant or in the presence of >10 pts.wt. but ≤30 pts.wt. alcoholic hydroxyl group-containing water-soluble polymer compound against 100 pts.wt. monomer mixture. <P>COPYRIGHT: (C)2008,JPO&INPIT |
