PURPOSE:An energetic ray-curable polymerizable resin composition having excellent adhesion to metal surfaces, prepared by combining a (meth)acryloyl group-containing polyester(urethane) resin with a hydroxyl group-containing polymerizable diluent. CONSTITUTION:At least 20wt% (meth)acryloyl group-containing polyester(urethane) resin prepared by using, as the starting material, a polyester-polyol containing 9-70wt% dimer acid residue is mixed with at most 80wt% polymerizable diluent (e.g., phenoxyethyl acrylate, ethyldiethylene glycol). The purpose polymerizable resin composition is prepared by using, s the diluent, one containing at least 10wt% hydroxyl group-containing monofunctional or polyfunctional reactive diluent (e.g., hydroxyethyl acrylate, trimethylolpropane diacrylate). |
