Patent ID: 7547477

Claim:
A coated metal formed article, comprising: a metal formed article, a zinc-containing porous coating layer laminated on a surface of the metal formed article, a phenol-modified silicon compound layer laminated on the zinc-containing porous coating layer, and a fluorine resin-containing layer laminated on the phenol-modified silicon compound layer, wherein the fluorine resin-containing layer contains a fluorine resin and at least one organic resin selected from a polyester resin, a polyacryl resin, a polyolefin resin, a polyurethane resin, and a polycarbonate resin, wherein an amount of the fluorine resin added is in a range of 1 to 200 parts by weight with respect to 100 parts by weight of the organic resin, and wherein when a thickness of the phenol-modified silicon compound layer is t 2 (μm) and a thickness of the fluorine resin-containing layer is t 1 (μm), a ratio of t 1 to t 2 is in a range of 0.05 to 50 so that dimensional accuracy and mechanical properties are increased.
