PROBLEM TO BE SOLVED: To obtain a radiation-curable resin compsn. which has a high hardness, is excellent in adhesion to a substrate, resistances to light and heat. etc., and is suitable for a protective coating by incorporating an acrylic ester of a bisphenol A diglycidyl ether polymer, dipentaerythritol monohydroxypentaacrylate, a radiation polymn. initiator, and inorg. particles into the same. SOLUTION: This compsn. contains, based on 100 pts.wt. sum of ingredients A and B, 10-50 pts.wt. acrylic ester of a bisphenol A diglycidyl ether polymer (A) of the formula (wherein is a p-phenylene group; and k is 1-10), 50-90 pts.wt. dipentaerythritol monohydroxypentaacrylate (B), 0.1-10 pts.wt. radiation polymn. initiator (C) which is decomposed by a radiation to generate free radicals and to initiate the polymn., and 0.1-10 pts. wt. inorg. particles (D) having an average particle size of 0.1-10 μm.
