1. A photocurable hygroscopic composition comprising:
- (a) a moisture-reactive organic metal compound,(b) a (meth)acrylate,(c) a carboxyl group-containing polymerizable monomer, and(d) a photopolymerization initiator,wherein the proportion of the moisture-reactive organic metal compound (a) is from 5 to 70 wt % based on the entire composition, and the proportion of the carboxyl group-containing polymerizable monomer (c) is from 0.1 to 50 mol % based on the moisture-reactive organic metal compound (a),wherein said moisture-reactive organic metal compound (a) is a metal alkoxide represented by the following formula;
M(OR)n wherein M is Al, B, Ti or Zr, R is an alkyl group, an alkenyl group, an aryl group, a cycloalkyl group, a heterocyclic group or an acyl group, and n is the valence of M.
