Production of composition excellent in solvent resistance for processing paper

Abstract

Abstract PURPOSE:To improve coating operability and drying properties and simultaneously solvent resistance as a paper coating composition by copolymerizing polyvinyl alcohol with a monomer having unsaturated and silane groups and acrylic or methacrylic monomer in a specific proportion. CONSTITUTION:(B) A monomer (e.g., vinyltrimethoxysilane) having an unsaturated and silane groups in an amount of 1-20 pts.wt. and (C) 19-280 pts.wt. (meth) acrylic monomer are copolymerized in (A) an aqueous solution of 100 pts.wt. (in the composition) polyvinyl alcohol or a derivative thereof to provide a composition consisting of an aqueous resin solution in which the monomers are partially graft copolymerized with the polyvinyl alcohol or derivative thereof. The above-mentioned composition is used as a binder, etc., in heat-sensitive recording paper to afford films excellent in water, heat resistance, etc.
