Provided is a production method for a curable resin with little viscosity after volatilization of a solvent, low volume shrinkage during curing, and excellent surface hardness, abrasion resistance, wear resistance, flexibility, heat resistance, mechanical strength, adhesion to substrates, adhesive strength, initial adhesiveness, chemical resistance, water resistance, and weather resistance. An acryl acrylate resin having a (meth)acryloyl group on the side chain thereof is produced by introducing a (meth)acryloyl group to the side chain of an acrylic resin (P) having a weight-average molecular weight (Mw) of 150,000 min. The acryl acrylate resin with a (meth)acryloyl group on the side chain thereof is produced by first producing, by suspension polymerization, the acrylic resin having a weight-average molecular weight (Mw) of 150,000 min., and then introducing a (meth)acryloyl group to the side chain of the acrylic resin (P). |
