PURPOSE:To obtain the titled composition having excellent impact strength, creep resistance, flexural strength, cast-moldability, fabrication quality, etc., by using a diamine obtained by adding amino groups to both terminals of polyalkylene glycol as a main curing agent, and adding the curing agent to a liquid epoxy resin. CONSTITUTION:The objective composition can be produced by mixing (A) a liquid epoxy resin (e.g. bisphenol-type epoxy resin such as bisphenol A diglycidyl ether, etc., and having a Gardner color of <=2, preferably <=1) with (B) a main curing agent consisting of a diamine obtained by adding amino groups to both terminals of a polyalkylene glycol (preferably polypropylene glycol diamine having a Gardner color of <=0.6).
