Zusammenfassung:	PURPOSE:To obtain a resin composition improved in weathering resistance, heat resistance, hydrolysis resistance and hot water resistance by mixing a specified acrylic urethane resin with a reactive diluent. CONSTITUTION:One g-equivalent of a urethane-moldified resin obtained by reacting a glycol component containing at least 50% glycol having a cyclohexane skeleton (e.g. cyclohexanedimethanol) with 1.1-2.0 g-equivalents of 2, 5-and/or 2, 6-diisocyanatomethylbicyclo[2.2.1]heptanes at 30-60 deg.C for 1-5 hr is reacted with 0.5-1.5 g-equivalents of an ethylenically unsaturated monomer having at least one hydroxyl group in the molecule (e.g. 2-hydroxyethyl methacrylate) at 50-70 deg.C to an NCO% of 0 to obtain an acrylic urethane resin having an ethylenically unsaturated group at each terminal. 100pts.wt. this resin is mixed with 5-200pts.wt. reactive diluent having at least one ethylenically unsaturated group in the molecule (e.g. methyl methacrylate).
