PURPOSE:A curable composition with excellent adhesion and water resistance, and good peeling strength against a metal, comprising a composition prepd. by dispersing a specified polymer in an epoxy compd. and a curing agent for the epoxy compd. CONSTITUTION:An epoxy compd. (a) of epoxy eq. 150-800 having on the average at least one 1,2-epoxy group in one molecule is mixed with 10-100wt%, based on the component (a), monomer mixt. (b) consisting of an adduct of a hydroxyacrylate with a isocyanate prepolymer and an ethylenically unsaturated monomer sush as butadiene and the resulting mixt. is subjected to reaction, in an inert gas atmosphere at 100-130 deg.C for 2-5hr to obtain a composition (A) consisting of the epoxy compd. in which a polymer is dispersed. Then a curing agent for the epoxy compd. such as ethylenediamine is added to the component A. |
