PROBLEM TO BE SOLVED: To obtain a hydrophilic surface treating composition and a hydrophilic surface treating membrane capable of imparting excellent hydrophilicity and its durability, corrosion resistance and antimicrobial activity to the surface of a material to be coated, especially the metal surface of a fin material for heat exchange or the like consisting of aluminum or its alloy, or the surface of various kinds of plastic products, glass products or the like for the purposes of antifog treatments, antistatic treatments or the like. SOLUTION: This hydrophilic surface treating composition contains a carboxyl group-containing water-soluble polymer molecule and chitosan as essential components. Herein, the carboxyl group-containing water-soluble polymer is contained at a ratio of 10-90 wt.% in terms of solid component, and at the same time, the chitosan is contained at a ratio of 1-30 wt.%. Further, the hydrophilic surface treating membrane is formed by using said hydrophilic surface treating composition. |
