Abstract: PROBLEM TO BE SOLVED: To obtain a coated product not generating while powder (ausbluehens) and not changing its strength and visual appearance with water by coating a molded product with a radiation-curable prepared product containing a polymer having ethylenic unsaturated double bonds and subsequently curing the coated product by the irradiation of UV light or electron beams. SOLUTION: The content of ethylenic unsaturated double bonds is usually 0.01-1.0 mole/100 g of polymer. The ethylenic unsaturated double bond is preferably a group of the formula: P-Z-X-CR =CHR [X is a single bond, CH2 or CO; Z is a single bond, O or NH; P is a 2-10C organic group or a single bond; R is H or methyl group; R is H, methyl group, phenyl group when X is CO or CO2 Y (Y is H or a 1-4C alkyl group)]. Silicones, polyurethanes, polyesters, polyethers, epoxy resins, melamine resins and methacrylate ester copolymers which have ethylenic unsaturated groups, respectively, are important as the polymer.
