PROBLEM TO BE SOLVED: To obtain a composition suitable for patching which is free from peel off at boundary face when patching defective parts broken out or found after a resin is completely cured, by containing a specific unsaturated resin and a copolymerizable monomer. SOLUTION: The objective resin composition is obtained by containing (A) an unsaturated polyester resin obtained by carrying out a reaction of a dibasic acid component comprising 50 to 100mol% of anα,β-ethylenic unsaturated dibasic acid and 50 to 0mol% of a saturated dibasic acid and a polyvalent alcohol component comprising 10 to 50mol% of 1,6-hexane diol and 90 to 50mol% of other polyvalent alcohol, and (B) a copolymerizable monomer such as styrene, divinylbenzene, methylmethacrylate, etc., in the ratio of (A)/(B) of 85/15 to 45/55, preferably, 80/20 to 50/50, most preferably 70/30 to 60/40. |
