Zusammenfassung: | PROBLEM TO BE SOLVED: To obtain a lubricating steel panel excellent in toughness and processability and capable of withstanding draw squeezing processing. SOLUTION: In the lubricating steel panel for a draw squeezed can, a film, which comprises a paint containing a hydroxyl group-containing polyester resin (A) with a number average mol.wt. of 8,000-50,000, an amino resin and/or a resole type phenol resin (B) and wax (C) with a softening point of 30 deg.C or higher, is formed on both surfaces of a metal panel in a dry coating amount of 10-85 mg/100 cm , and the coefficient of dynamic friction at 60 deg.C of the film is 0.03-0.20 and the pencil hardness at 60 deg.C thereof is not less than H. |
