STAINLESS STEEL SHEET COVERED WITH ALKALI-SOLUBLE PROTECTIVE COAT

摘要

A stainless steel sheet having a protective coat for protecting the surface of the sheet in press working on the surface, wherein the protective coat is composed of a lower coating made from an epoxy-modified acrylic resin prepared by modifying an acrylic resin having an acid value of 40 to 300 and a glass transition temperature of 0 to 20 DEG C with 3 to 20 % by mass of an epoxy oligomer having a molecular weight of 500 to 2000 and an upper coating made from an acrylic resin having an acid value of 40 to 300 and a glass transition temperature of 40 to 80 DEG C, these coatings being formed on the surface of the sheet successively in a total thickness of 1 to 20 mu .
