Abstract
An anaerobically curing adhesive sealing composition comprising (A) a mono(meth)acrylate monomer represented by formula (I) ##STR1## wherein R.sub.1 represents a hydrogen atom or a methyl group; and R.sub.2 represents ##STR2## and (B) a (meth)acrylate prepolymer having a urethane structure in the main chain thereof and having an average molecular weight of 10,000 or more and further containing (C) a (meth)acrylate prepolymer having a urethane structure in the main chain thereof and an average molecular weight of at most 5,000. The sealing composition exhibits, upon curing, excellent elasticity and properties to follow an adherend while retaining excellent resistance to oil and heat as possessed by acrylate type reactive sealing compositions.
