PURPOSE:To obtain the titled composition composed of an epoxy resin having plural epoxy groups in the molecule, a highly crosslinked polysulfide polymer, and an amine, curable rapidly at a low temperature, and giving a resin having excellent toughness, flexibility, chemical resistance, etc. CONSTITUTION:The objective composition can be prepared by compounding (A) an epoxy resin having >=2 epoxy groups in one molecule (e.g. bisphenol-type epoxy resin) with (B) preferably 20-150PHR of a highly crosslinked polysulfide polymer [preferably the compound of formula (X is 1.5-2.5; R and R' are alkyl containing 0-2 alkyl groups; m and p are 0 or 1; n is 1-20) having an average molecular weight of 500-2,000 and containing 20-60mol% crosslinking agent] and (C) preferably 2-20PHR of an amine [e.g. 2,4,6-tris(dimethylaminomethyl) phenol]. USE:Paint for automobile, ship, etc.
