Aqueous surface treating agent and an article using the same

The present invention is a 100% modulus to provide an aqueous polyurethane (A) and the article using the same aqueous surface treatment agent and is characterized by containing carbodiimide-based crosslinking agent (B) is 10 to 20 MPa. Aqueous surface treating agent of the present invention is free of organic solvent substantially synthetic leather, can grant surface excellent wear resistance of various articles such as polyvinyl chloride (PVC) leather, flexible such as a synthetic leather It does not impair the. Also, if by applying the matte to the surface of an article such as a synthetic leather and design of luxury may further an aqueous surface treating agent containing a filler (C).
