PURPOSE:To provide the subject lubricant composed of a maleic acid/styrene copolymer (salt) and an amine-epoxide adduct of a specific hydrocarbon compound and useful for coating various metals to form a lubrication film exhibiting excellent lubricity, wettability with water and hydrophilic property and removable with a water-based detergent. CONSTITUTION:The objective lubricant is composed of (A) a copolymer (or its salt) containing (i) a maleic acid compound such as maleic acid, fumaric acid, their esters, salts, amides, imides, anhydrides, etc., and (ii) a styrene compound such as styrene, alkylstyrene, their polymerized compounds, derivatives, etc., as essential monomer components and (B) an amine-epoxide adduct of a compound having 10-30C hydrocarbon group. |
