Abstract
Abstract This invention relates to a cross-linkable, cationic radiation curable composition comprising (a) a non-volatile vinyl ether, epoxide, acrylate or an oligomer thereof (b) a cationic photoinitiator and (c) a divinyl ether polyacetal oligomer having the formula <IMAGE> wherein n has a value of from 1 to 50; X is uniformly sulfur or oxygen; R is C2 to C4 alkeneoxy alkylene, poly(alkyleneoxy) alkylene, or a branched, linear or cyclic C2 to C20 alkylene and R' is phenylene, diphenylene methane, diphenylene propane, xylylene, tolylene, or a branched, linear or cyclic C2 to C20 alkylene optionally substituted with an ether, ester, carbonate, carbamate, C2 to C4 alkyleneoxy alkylene or poly(C2 to C4 alkyleneoxy) alkylene radical. The invention also relates to the composition cured on a substrate.
