Energy curable compositions which can be cured in the presence of air by exposure to actinic radiation contain (A) at least one unsaturated oligomer selected from the group consisting of (I), the reaction product of at least one unsaturated active hydrogen- containing compound, at least one polyetherester, said polyetherester having in its main chain the residue of at least one poly(alkylene oxide) polyol; and (II) the reaction product of (i) at least one olefinically unsaturated compound containing a single reactive carboxy or hydroxyl group and (ii) at least one compound selected from the group consisting of poly(alkylene oxide)polyols, hydroxyl-terminated polyetheresters and carboxyl-terminated polyetheresters, said polyetheresters having as a characteristic feature the residue of at least one poly(alkylene oxide) polyol in the main chain of said polyetherester; (B) an ethylenically unsaturated monomer; and (C) a photosensitizer. |
