To provide a novel resin compsn. for a cured coating film which compsn. satisfies the requirements concerning heat resistance, chemical resistance, adhesive properties, applicability, clarity, scratch resistance, etc., and has a greatly improved resistance to an IPA vapor and to provide a color filter protection film and a color filter both produced from the same.
This compsn. comprises 100 pts.wt. copolymer resin obtd. by copolymerizing 60-90wt.% glycidyl methacrylate and/or glycidyl acrylate, 10-40wt.% 7-20C alicyclic methacrylic and/or acrylic ester having a tert-carbon atom in the alicycle, and 0-30wt.% other copolymerizable unsatd. monomer, 20-200 pts.wt. copolymer resin obtd. by copolymerizing an N-substd. maleimide, acrylic and/or methacrylic acid, and if necessary another unsatd. monomer, 5-50 pts.wt. at least one compd. selected from among polycarboxylic anhydrides and polycarboxylic acids, and 30-100 pts.wt. functional silane coupling agent. A color filter protection film and a color filter are produced from the compsn.
