发明名称 Clear-coated stainless steel sheet with excellent pressure mark resistance and scratch resistance
摘要 A clear-coated stainless steel sheet with excellent anti-pressure printing property and excellent scratch resistance, including: a stainless steel sheet; and a clear-coated film coated on either one or both of two main surfaces of the stainless steel sheet, wherein the clear-coated film contains a thermosetting resin composition (A) and resin beads (B) at a content in a range of 0.5 parts by mass to 4.0 parts by mass relative to 100 parts by mass of a solid content of the thermosetting resin composition (A), the thermosetting resin composition (A) includes an acrylic resin (AI) and a cross-linked curing resin (A2) composed of a blocked isocyanate resin and an amino resin which cross-link and cure the acrylic resin (A1), the acrylic resin (A1) includes one or more cross-linking functional groups selected from a hydroxyl group, a carboxylic group, and an alkoxy silane group, the acrylic resin (A1) has a glass transition temperature of 30°C to 90°C, and has a number average molecular weight of 3000 to 50000, and an average particle diameter of the resin beads (B) is in a range of2.4 to 5.0 µm, and the average particle diameter of the resin beads (B) is in a range of 0.8 times to 1.0 time a film thickness of the clear-coated film.
