Abstract
Abstract A composition substantially comprising diallylphthalate prepolymer and acrylonitrile or a mixture of acrylonitrile and an alkylacrylate is cured by means of an electron beam as well as other ionizing radiations to form a cross-linked resin having excellent properties. A vinyl phosphate incorporated in the composition makes the cured coating anticorrosive and adhesive to metal surface. The composition is useful as a coating or adhesion agent, or for the manufacture of decorative plywood, colored coiled steel sheet, etc., and for preparing an anticorrosive paint.
