PURPOSE:To provide a curable resin composition containing a specific epoxy vinyl ester resin, a polymerizable vinyl monomer and an organic solvent at specific ratios, having excellent heat aging characteristics, corrosion resistance, mechanical properties, adhesivity, etc., and useful as a molding material, etc. CONSTITUTION:The objective composition can be produced by compounding (A) 95-30pts.wt. of an epoxy vinyl ester resin produced by reacting (i) a bisphenol novolac epoxy resin produced by the reaction of epichlorohydrin or beta-methylepichlorohydrin to a condensation product of a bisphenol and an aldehyde with (ii) preferably 0.8-1.0 equivalent [based on epoxy group of the component (i)] of an unsaturated monobasic acid (e.g. acrylic acid) at 80-120 deg.C and (B) 5-70pts.wt. of a polymerizable vinyl monomer (e.g. styrene) and/or an organic solvent (e.g. methanol). |
