PROBLEM TO BE SOLVED: To provide an inexpensively and safely produceable resin film for improving resistance, having the resistances such as outdoor weather resistance and chemical resistance equal to that obtained by using a conventional photocurable resin coating material. SOLUTION: The resin film for improving the resistance is obtained by coating a visible light-curable silica-polysiloxane coating composition containing 0.1-15 pts.wt. photopolymerization initiator having an excitation wavelength longer than 380 nm wavelength in the visible light range as a photopolymerization initiator based on 100 pts.wt. silica-silicone oligomer having an acryloyl group and a silanol group at both terminals of the molecule, and containing 20-80 pts.wt. silica fine particles bonded to the silanol group by a condensation reaction.
