The above-mentioned plated steel sheet is manufactured by subjecting a cold-rolled steel sheet to a zinc dip-plating treatment in a zinc dip-plating bath having an aluminum content of from 0.05 to 0.30 wt. %, in which the temperature region causing an initial reaction for forming an iron-aluminum layer is limited within a range of from 500.degree. to 600.degree. C., an alloying treatment in which an alloying treatment temperature is limited within a range of from 480.degree. to 600.degree. C., and a temper-rolling treatment. It is possible to further impart an excellent image clarity after painting to the above-mentioned plated steel sheet by replacing the above-mentioned condition (2) with a condition that a bearing length ratio tp (2 .mu.m) in a profile curve is within a range of from 30 to 90%.

摘要： A steel sheet plated with zinc or a zinc alloy carries a chromate film formed on each side thereof and having a coating weight of 1 to 200 mg/m.sup.2 in terms of metallic chromium, and a black film formed at least on the chromate film on one side thereof. 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.
