ABSTRACT:
A coated article comprising a stainless steel base having an etched surface and having on the etched surface a coated layer. The coating layer may comprise a fluororesin and can be provided: after sensitizing the stainless steel base through heating, treating with an acid, subjecting to etching, and subjecting to a solution treatment; after immersing in an aqueous acid solution or an aqueous ferric chloride solution to cause the base to be dissolved to such an extent that the gloss of the surface disappears; after uniformly abrading the surface of the base through buffing or blasting to the weight corresponding to a thickness of 1.0 .mu.m or more of the base, immersing in an aqueous acid solution or an aqueous ferric chloride solution to cause the base to be dissolved to such an extent that the gloss of the surface disappears, and subjecting to etching; or after subjecting to electrolytic etching at 15.degree. C. or less.
