[PROBLEMS] To reduce the amount of industrial waste (environmental conservation), and when the forced drying is not performed after the lubrication process (room temperature drying, standing at room temperature), or a metal that is difficult to completely dry such as the inner surface of a steel pipe Providing lubricating film agents that can impart excellent lubricity to products even in a water-containing state, and technologies related thereto. A water-containing lubricating film agent for use in metal plastic working performed in a water content state having a water content of 3 to 50 mass%, comprising at least one lipophilic lubricating component (A) and / or at least one type The solid lubricant (B) having a cleavage property is dispersed in water, and at least one water-soluble lubricant component (C) selected from the group consisting of fatty acid components having 12 to 20 carbon atoms is (C ) / [(A) + (B)] = 0.05 to 0.5, the water-containing lubricating film agent that is dissolved on the water phase side. [Selection figure] None |
