PURPOSE:The titled composition, prepared by incorporating a photopolymerization initiator with a prepolymer obtained by reacting a specific polyester resin with a diisocyanate compound and then a specific monomer, and having the air drying property and improved adhesiveness and flexibility. CONSTITUTION:(A) A low-molecular-weight polyester, preferably having a molecular weight of 300-1,000, and containing (i) an allylic ehterified dihydric alcohol, e.g. trimethylolpropane monoallyl ether, or the component (i) and (ii) (methyl)tetrahydrophthalic 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 give a prepolymer, which is incorporated with a photopolymerization initiator, e.g. benzoin.
