Abstract
The present invention addresses the problem of providing: a metal surface treatment agent which can form a film having excellent corrosion resistance and excellent hydrophilicity on or over a surface of a metal material; a method of producing a metal material having a film by using the metal surface treatment agent; and a metal material having a film, which is obtained by the method. A chemical agent, which contains prescribed amounts of a water-soluble or water-dispersible resin (A) and a compound (B) having a nitrile group and an amino group, is capable of forming a film having excellent corrosion resistance and excellent hydrophilicity on or over a surface of a metal material and, therefore, can solve the above-described problem.
