PROBLEM TO BE SOLVED: To provide a lubricant steel sheet having excellent formability by singly coating with only a water base coating agent for a lubricant film without performing chromate treatment. SOLUTION: The lubricant steel sheet is composed of a steel sheet and a lubricant film formed at least on one side of the steel sheet. The steel sheet is a stainless steel sheet, a stainless steel-aluminum plated steel sheet or an aluminum plated steel sheet. The lubricant film is formed by coating a water base coating agent, so as to be dried. The water base coating agent comprises a resin, polyolefin wax and fluorozirconate, and also has a pH of 4.5 to 8. The resin includes a polyester resin, and the content of the polyester resin in the solid component in the water base coating agent is≥70 mass%. COPYRIGHT: (C)2008,JPO&INPIT |
