Abstract
An aqueous lubrication treatment liquid for a cold plastic working of a metallic material comprises 50 to 400 g/l of a solid lubricant, for example, MoS.sub.2, 1 to 40 g/l of a surfactant, 10 ppm to 5000 ppm, in terms of colloidal titanium compound, water, and optionally, 5 to 150 g/l of a binder and 4 to 160 g/l of a metallic soap. This liquid exhibits a strong bonding to the metallic material and an excellent lubricating property, and prevents rusting of the metallic material.
