    摘要： A black steel sheet having a sufficiently small coating thickness to allow the welding of the steel sheet, and yet exhibiting an excellently black surface, but also having high corrosion resistance, adhesive strength and formability. It is a steel sheet having a surface plated with zinc or zinc alloy, and carrying a chromate film formed on its plated surface, and a black film formed on the chromate film from a composition comprising specific proportions of a water-soluble or water-dispersible thermosetting resin and a water-soluble black dye, and having a sufficiently small thickness. The composition may further contain a solid lubricant, or a granular rust-inhibitive pigment, or both.

The black film contains 100 parts by weight of a thermosetting resin which is soluble in an organic solvent, 1 to 200 parts by weight of a black dye which is also soluble in an organic solvent, and 1 to 100 parts by weight of organic resin particles. It may further contain 1 to 100 parts by weight of fine inorganic particles, or a solid lubricant, or both. The black film has a thickness of 0.3 to 5.0 microns which is sufficiently small to permit the welding of the sheet, and yet has an excellently black surface. The organic resin particles, etc., which are used as a matting agent, give the film a surface of low gloss which resists visible staining by fingerprints.
