Abstract
The photoreactive adhesive composition of the present invention is cured in a short time and has a low percentage of water absorption and excellent adhesiveness after curing because it contains a monofunctional radically-polymerizable substance, a polyfunctional cationically-polymerizable substance, a noncrystalline polyester resin, a photoradical polymerization initiator, and a photocationic polymerization initiator.
