PURPOSE: To provide a lubricating resin treated steel panel improved in multistage press moldability at a high speed and processed part corrosion resistance.
CONSTITUTION: A lubricating resin treated steel panel having resin films on both surfaces thereof and excellent in press moldability and processed part corrosion resistance is constituted so that chromate films are provided to both surfaces of a galvanized or zinc or aluminum alloy plated steel panel in an adhesion amount of 5--200mg/m2 per a single surface as metal chromium and resin films formed from a resin compsn. are provided on both surfaces of the steel plate in an adhesion amount of 0.3-3.0g/m2 per a single surface on a dry wt. basis. The resin compsn. is obtained by adding 10-80 pts.wt. of silica and 1-20 pts.wt. of a polyolefin wax mixture containing polyolefin wax having a large particle size and polyolefin wax having a small particle size in a wt. ratio of (5:95)-(95:5)to 100 pts.wt. of a resin having a hydroxyl group and/or a carboxyl group.
