Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a curable resin composition excellent in weather resistance, moisture resistance, water resistance, salt water resistance, and stain resistance, curable at a relatively low temperature, free from reduction in volume after curing and excellent is flexibility, by blending a specific alkenyl group-containing acrylic copolymer. SOLUTION: This composition contains (A) an organohydrogenopolysiloxane containing at least two hydrosilyl groups in the molecule, (B) an alkenyl bond- containing acrylic copolymer having 40-100 iodine value and 1,000-100,000 number average molecular weight and composed of (i) an alkenyl (meth)acrylate in which the number of carbon atoms of the main chain an alkenyl group is >=4, (ii) a cyclohexenyl alkyl (meth)acrylate, (iii) an alkenyl bond-containing acrylic copolymer containing either of a mono-, di-, tri- or tetraethylene glycol monoalkenyl ether or a monocycloxenyl alkyl either (meth)acrylate and (C) a hydroxilylating catalyst in the molar ratio of the hydrosilyl group in the component A to the alkenyl bond in the component B of 0.5-4.
