PROBLEM TO BE SOLVED: To provide a one-component type aqueous putty composition for repair having long pot life, making specific equipment unnecessary, being simply useable, excellent in safety and suitably used when each car owner repairs own car. SOLUTION: The one-component type aqueous putty composition for repair comprises 100 pts.wt. (as a solid content) carbonyl-hydrazide-based one-component normal temperature crosslinking type emulsion as a main agent and 250-700 pts.wt. filler and has 75-90 wt.% solid content in putty. A crosslinking type emulsion composed of (meth)acrylic resin having a keto group with hydrazine or a crosslinking type emulsion comprising a composition of a diacetoneacrylamide with polyamine (containing hydrazine hydrate) is preferably used as the one-component normal temperature crosslinking type emulsion. The filler comprises preferably 100-400 pts.wt. barium sulfate. COPYRIGHT: (C)2005,JPO&NCIPI
