PURPOSE: The titled novel composition that is composed of one solution containing acrylic monomers, organic peroxide and other components and of the other solution containing acrylic monomers, curing accelerator and others, further containing a modified nitrile rubber bearing groups containing double bonds, thus giving coating films with high adhesion strength and adhesivity to oil surface.
CONSTITUTION: For example, (A) one solution containing (i) acrylic monomers, (ii) a modified nitrile rubber into which polymerizable or copolymerizable double bonds are introduced through ionic bonds (iii) organic peroxides, (iv) if necessary, stabilizers and (B) the other solution containing (i) acrylic monomers, (ii) curing accelerators, (iii) if necessary, a gel stabilizer such as a mixture of at least one selected from alkali metal, zinc and nickel organic acid salts and aliphatic amine organic acid salts are used to give the objective composition.
EFFECT: The resultant composition are excellent in heat resistance and its storage stability is improved by using a gel stabilizer in particular.
