An ultraviolet curable resin composition, which comprises a cationic photopolymerization initiator (B) and a urethane prepolymer (A) having a structure represented by the general formula (); (wherein Rand Reach independently represent an alkylene group, R, Rand Reach independently represent an alkyl group or hydrogen atom, Rand Reach independently represent an alkylene group having 2 to 4 carbon atoms, a represents 0 or 1, and b and c each independently represent an integer of 0 to 10).

Ultraviolet-curable resin composition containing a polyfunctional oxetanyl group

The present invention relates to a composition which is curable by radiation such as an ultraviolet ray or an electron beam. Specifically, the present invention relates to a curable composition which is useful for coatings and inks. The present invention provides a radiation curable composition that is highly cationically polymerizable and highly adhesive to substrates. A radiation curable composition of the present invention includes, as essential ingredients, a cationically polymerizable compound (a) represented by the following general formula 1 (wherein, R represents an alkyl group of 1 to 10 carbon atoms, Rrepresents a hydrogen atom or a methyl group, n represents a number from 1 to 4, and m represents a number from 0 to 10); a cationic photoinitiator (b); and water (c).
