<p><P>PROBLEM TO BE SOLVED: To provide a resin composition which can form highly flat cured films, is suitably be used for forming optical device-protecting films having high transparency, surface hardness and various kinds of excellent resistance such as heat and pressure resistance, acid resistance, alkali resistance, spattering resistance, and etching resistance, and has excellent storage stability, to provide a method for forming a protecting film from the composition, and to provide a protecting film formed from the composition. <P>SOLUTION: This composition comprises a copolymer comprising (a1) polymerization units originated from a polymerizable unsaturated compound having an oxiranyl group or oxetanyl group, (a2) polymerization units originated from a polymerizable unsaturated compound having a specific structure and represented by 1-diethylpropyl methacrylate, and (a3) polymerization units different from the polymerization units (a1) and (a2). The protecting film is formed from the composition. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
