PROBLEM TO BE SOLVED: To obtain a curable resin composition containing an alkenylsuccinic acid of a specific structure which has excellent thickening property and thickening stability. SOLUTION: This curable resin composition comprises (a) a curable polymer having 5,500 to 50,000 weight average molecular weight, (b) a polymerizable monomer and (c) an alkylsuccinic acid and/or alkenylsuccinic acid having 8 to 30 total carbons, where the content of (c-1) an alkylsuccinic acid and/or alkenylsuccinic acid having a structure expressed by general formula (1) (wherein R represents an alkyl group or an alkenyl group having 3 to 25 carbons) contained in the curable resin composition to (c) is in the range of 0.8 to 1.0 by weight ratio.
