PROBLEM TO BE SOLVED: To provide a one-pack cold-setting composition capable of improving adhesion to a base material. SOLUTION: This one-pack cold-setting composition contains a component (A) comprising an aqueous resin emulsion which contains a copolymer obtained by conducting emulsion polymerization of an unsaturated monomer mixture containing a carbonyl group-containing unsaturated monomer and other unsaturated monomers, a component (B) comprising a polyfunctional hydrazide compound having three or more hydrazide groups in its molecule, and a component (C) comprising a quaternary ammonium salt. The copolymer which composes the aqueous resin emulsion of the component (A) preferably has a glass transition temperature of -30°C to 20°C. The carbonyl group-containing unsaturated monomer of the component (A) is preferably contained in an amount of 5-30 mass% in the unsaturated monomer mixture. Further, the carbonyl group-containing unsaturated monomer preferably comprises an acetoacetyl group-containing unsaturated monomer. COPYRIGHT: (C)2007,JPO&INPIT
