Abstract:
1. An aqueous surface-treating agent, which comprises a silicone oil aqueous emulsion, a polyurethane resin aqueous emulsion, and a silane compound represented by the following general formula: where R wherein the polyurethane resin aqueous emulsion is a mixture of (a) an aqueous emulsion containing a hydrazide and a carbonyl group-containing polyurethane resin, and (b) a silanol-modified polyurethane resin aqueous emulsion wherein the silanol-modified polyurethane resin has, in the polyurethane structure, silanol groups, which turn to siloxane bonds by condensation cross-linking reaction after surface treating, in a ratio by weight of solid matter sum total of (a):(b) is 5-95:95-10.
