<p><P>PROBLEM TO BE SOLVED: To provide a metal surface treatment agent having excellent storage stability, low temperature short time drying properties, fingerprint resistance, corrosion resistance and adhesiveness to a top coat. <P>SOLUTION: (1) The metal surface treatment agent contains a water dispersion of a carbonyl group-containing urethane urea resin (A), a curing agent (B) containing two or more functional groups, in one molecule, which can react with the carbonyl group in the resin (A), silica particles (C), and at least one metal compound (D) selected from Ti, Zr and V. (2) In the metal surface treatment agent, the functional group of the curing agent (B) has a hydrazide group and/or a semicarbazide group. (3) The metal compound (D) is at least one selected from titanium hydrofluorate, zirconium hydrofluorate, zirconium ammonium carbonate, a metavanadate and sulfuric acid. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
