PURPOSE: To provide a highly reliable ink-jet recording method by which the corrosion of metal in contact with liq. is minimized, the breakage of a metallic wire due to electric corrosion and dissolution is prevented especially when the metal is used in an electrode, and the life of the head of an ink-jet recorder is prolonged.

CONSTITUTION: A liq. such as a recording soln. is brought into contact with the surface of a metal in a recorder. In this case, a liq. contg. a dye for aluminum and a film forming soln. such as an org. carbonyl compd. and a nitrogen- contg. org. compd. and kept at pH7-10 is used to protect the metal surface with an insulating protective film to be formed. Recording is conducted by the ink-jet recorder using such an ink.
