PURPOSE:To provide a lubricant oil especially having lubricity and high milling cleanness in thin steel plate rolling processes and used for processing processes, spinning processes, etc., by containing the esterification product of an aminopolyalcohol having one or more tert. nitrogen atoms with a fatty acid and a dibasic acid. CONSTITUTION:The objective lubricant oil contains the esterification product of (A) a bi-- tetravalent aminopolyalcohol of formula I-V (R1 is 1-20C alkyl, alkenyl, cyclohexyl or phenyl; R2 is 2-6C alkyl or cyclohexyl; X is H or CH3; n is 1-3) and having one or more tert. nitrogen atoms with (B) (i) a 6-30C fatty acid and (ii) a 2-36C dibasic acid (e.g. thioglycolic acid or phthalic acid). |
