Abstract: The present invention addresses the problem of providing: a metal plate coating material with which it is possible to form a coating film that has extremely high storage stability, that does not exhibit yellowing, and that is not prone to staining with rain streaks; and a method for producing a coated metal plate using the metal plate coating material. The metal plate coating material for solving the problem contains: at least one of a mixture of a fluorine-containing resin and a (meth)acrylic resin and a copolymer of a fluorine-containing monomer and a (meth)acrylic group-containing monomer; a silicone resin; and a zinc carboxylate salt catalyst.

Abstract: A ferritic stainless steel sheet is a ferritic stainless steel sheet which is temper rolled after bright annealing and has a passivation film. The area ratio of minute defects having an area of 10 ?m2 or more on the surface of the steel sheet is 0.2% or more and 1.5% or less. In addition, the thickness of the passivation film is 1 nm or more and 10 nm or less, the average concentration of Si in the passivation film is 10 at % or more and 20 at % or less, and the average concentration ratio of Si, Al, Cr and Fe in the passivation film component is (Si+Al+Cr)/Fe>1.0.

Abstract: In an austenitic stainless steel sheet, the arithmetic average roughness Ra is 0.2 ?m or more and 1.2 ?m or less. In addition, the dull pattern transfer rate on the steel sheet surface is 15% or more and 70% or less. Furthermore, micropits with a depth of 0.5 ?m or more and an open area of 10 ?m2 or more which are formed on the steel sheet surface have an existing density of 10.0 or less per 0.01 mm2 and an open area ratio of 1.0% or less. In addition, a film formed on the steel sheet surface is constituted from an oxide containing SiO2 as a main constituent, which oxide contains at least Si, N, Al, Mn, Cr, Fe, Nb, Ti and O as film-forming elements other than C, wherein the Si content is 10 at % or more, and the N content is 10 at % or less.

Abstract: A stainless steel plate is manufactured by performing temper rolling using a dull roller after the finish cold rolling and bright annealing. The stainless steel plate has an arithmetic mean roughness Ra of 0.2 to 1.2 ?m in a direction perpendicular to the rolling direction of the steel plate surface. Furthermore, the stainless steel plate has a transfer ratio of 15 to 70% which is an area ratio of a portion onto which a dull pattern is transferred relative to the steel plate surface. In addition, the micro-pits being formed in the steel plate surface, having a depth of 0.5 ?m or more, and having an opening area of 10 ?m2 or more, have an existing density in the steel plate surface of 10.0 or less per 0.01 mm2, and an opening area ratio in the steel plate surface of 1.0% or less.
