ABSTRACT:
A hydrophilizing agent comprising: (a) a hydrophilic polymer which is a copolymer of N-vinylacetamide with a polymerizable monomer having a COOX group (wherein X means hydrogen, an alkali metal atom, or an ammonium salt); (b) a water-soluble urethane resin; and (c) inorganic silica. It imparts hydrophilicity and corrosion resistance to the surface of a metallic material.
