Zusammenfassung:	PURPOSE:The titled composition, prepared by incorporating a photopolymerization initiator with a prepolymer obtained by reacting a specific polyester resin with a diisocyanate and then a specific monomer, and having the air-drying property and improved adhesiveness and flexibility. CONSTITUTION:(A) A low-molecular-weight polyester resin, preferably having a molecular weight of 500-2,000, and containing an addition reaction product of (i) a dicyclopentadiene containing a hydroxyl group, e.g. the compound of the formula, and/or allylic etherified monohydric alcohol, e.g. allyl alcohol, with (ii) a trifunctional carboxylic acid, e.g. trimellitic acid, and/or a tetrafunctional carboxylic acid, e.g. pyromellitic anhydride, as a component is reacted with (B) a diisocyanate compound, e.g. lysine diisocyanate, and then (C) an acrylic monomer containing active hydrogen, e.g. acrylamide, to afford a prepolymer, which is then incorporated with a photopolymerization initiator, e.g. benzoin.
