The poly (meth) acrylate used in the present invention includes dipentaerythritol dihydroxytetraacrylate, dipentaerythritol dihydroxytetramethacrylate, dipentaerythritol monohydroxypentaacrylate, diopentaerythritol monohydroxypentamethacrylate, There are six kinds of dipentaerythritol hexaacrylate and dipentaerythritol hexamethacrylate, which are used alone or as a mixture. The compounding amount is 5 to 70 relative to 100 parts by weight of diallyl phthalate resin or a mixed resin of unsaturated polyester resin and diallyl phthalate resin.
A range of parts by weight, preferably 10 to 50 parts by weight is suitable.
If the amount is less than 5 parts by weight, the effect of improving the surface properties, which is the object of the present invention, cannot be sufficiently obtained. If the amount is more than 70 parts by weight, the cured product becomes too hard and becomes brittle, and the resin becomes sticky during processing to improve workability. This will cause problems.
