Patent ID: 7981988

Claim:
An ultraviolet radiation-polymerizable composition comprising: (a) an acrylated monounsaturated fatty acid alkyl ester represented by the following general formula: wherein R is an alkyl group, R 1 is an alkylene group, R 2 is an alkyl group or H, A is represented by one of the following general formulae: wherein R′ is H or CH 3 , and —R 1 -A-R 2 has from about 14 to about 22 carbon atoms in the catenary chain; (b) a monoethylenically unsaturated (meth)acrylic acid ester of a non-tertiary alkyl alcohol in which the alkyl group has from 1 to 20 carbon atoms; and from about 0.01 to about 5 parts by weight of a photoinitiator per 100 parts by weight of said composition wherein said photoinitiator is absorbent to ultraviolet radiation in the wavelength range of from 380 to 450 nm.
