<P>PROBLEM TO BE SOLVED: To provide an ultraviolet curing liquid composition which can be cured even in a portion which ultraviolet rays do not reach, in the case of curing using ultraviolet rays; and to provide a cured resin using the same. <P>SOLUTION: The liquid composition includes a liquid polymer having an acid anhydride group, and a photogeneration-type latent amine curing agent in which an amine protective group escapes by ultraviolet rays to generate a polyamine compound. The photogeneration-type latent amine curing agent is preferably the one having two or more structures represented by -NH-COO-R<SP POS="POST">1</SP>in one molecule. R<SP POS="POST">1</SP>is an o-nitrobenzyl group, a substituted o-nitrobenzyl group, a ketoimino group, an α-benzoylbenzyl group, a substituted α-benzoylbenzyl group, a dimethoxybenzyl group, or a substituted dimethoxybenzyl group. <P>COPYRIGHT: (C)2012,JPO&INPIT |
