Filed: 1987-09-30
Abstract: PURPOSE:To obtain an adhesive composition curable within a short time at low temperature and excellent in adhesiveness, by mixing a compound having a polymerizable ethylenically unsaturated bond with a photopolymerization initiator, a peroxy ester and a bivalent cobalt compound. CONSTITUTION:This adhesive composition comprises a compound (A) having a polymerizable ethylenically unsaturated bond, a photopolymerization initiator (B), a peroxy ester (C) and a bivalent cobalt compound (D). It is desirable for obtaining good adhesive strength that said compound (A) contains an unsaturated polyester and/or a polyurethane poly(meth)acrylate. Because an unsaturated polyester and a polyurethane poly(meth)acrylate are usually liquid having high viscosity at room temperature and are very poor in workability as an adhesive, it is necessary to use them together with a low viscosity (meth)acrylate. In order to improve the adhesion to various materials, it is desirable to use them together with other (meth)acrylates.
