PROBLEM TO BE SOLVED: To obtain the subject composition containing a hydrolysate of an alkylsilicate and a specific solvent, capable of being used singly as a hard coat and obtaining a coated membrane excellent in heat resistance, weather ability, antifoulancy, chemical resistance, etc., by blending with a resin, etc., and useful for a coating material, an adhesive, etc. SOLUTION: This curing composition contains (A) a hydrolysate of a alkylsilicate (A 1 ) (e.g. a fine particle like material containing methoxy or ethoxy group and having <50Å inertial radius) and (B) a solvent having a higher boiling point than that of alcohol generated by the hydrolysis of (A 1 ) (e.g. a solvent not having a group capable of making an ester interchange with alcohol of the component (A) such as methyl isobutyl ketone and xylene, propylene glycol monomethyl ether and diethylene glycol monoethyl ether).
