Document Type and Number:
Japanese Patent JP2002503282
Kind Code:
A
Abstract:
A radiation curable composition comprising a urethane oligomer with a polyester backbone which composition, when cured, has improved hydrolytic stability. The composition comprises a urethane oligomer, having a polyester backbone with a number average molecular weight of less than about 1000, wherein the polyester backbone is at least in part based on a diol component wherein at least one carbon at the beta -position with respect to a hydroxyl group bears two carbon-containing substituents having a total of at least three carbon atoms. Alternatively, when the composition comprises a urethane oligomer with a number average molecular weight of less than about 2000, having a polyester polyol backbone with a number average molecular weight of less than about 1000, the polyester backbone is at least in part based on a diol component wherein at least one carbon at the beta -position with respect to a hydroxyl group bears at least one carbon-containing substituent.
