In a process to facilitate the cold deformation of metals, a lubricant film is applied by first applying and drying an aqueous solution or dispersion of a water-soluble thermoplastic resin containing melamine, cyanuric acid or isocyanuric acid adduct on the metal surfaces and then drying with metal soap and / or treated with a lubricating oil.n n n The aqueous solution or dispersion preferably contains resin to adduct in a weight ratio of 1: 0.3 to 1: 2.n n n The layer weight of the dried resin film should be 0.3 to 30 g / m 2 . |
