摘要：
A composition for metal surface treatment capable of forming films and imparting excellent corrosion resistance in relation to metallic materials, in particular, metal formations having complex shapes through a single dipping step. A composition for metal surface treatment contains 5 to 30% by weight of a nonionic and/or cationic water-based resin, 100 to 1,000 ppm of trivalent Bi ions and an aminopolycarboxylic acid at 0.5 to 10 times in molar concentration based on the Bi ions.
