<P>PROBLEM TO BE SOLVED: To obtain a curable resin composition so improved that problems related to moldability, such as separation of a resin component from a filler and formation of voids and warpage in molding, are prevented from occurring, while good physical characteristics of strength specific to an unsaturated resin which is formed by giving (meth)acryloyl groups to an epoxy resin are maintained, properties of the composition in case of being charged into a molding tool are excellent, flowability is excellent when a cured material therefrom is molded, an excellent external appearance is given to a molded product obtained therefrom, and further the molded product, including an electric/electronic part of various kinds, having excellent resistance to water absorption and resistance to hot water is obtainable therefrom, to provide a molding material, and to provide a fuel cell separator. <P>SOLUTION: The curable resin composition contains (A) an unsaturated resin which is obtained by reacting the epoxy resin with (meth)acrylic acid anhydride, is solid at ordinary temperature, has a double bond equivalent of 200-500, an ester value of 100-300, and a hydroxy value of ≤130, and has the (meth)acryloyl groups, (B) an ethylenic unsaturated monomer, and (C) a radical polymerization initiator. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
