PURPOSE:A metal-rolling oil having excellent rolling properties, employing a compound prepared by the reaction between an alkylene oxide-added polyamine and an aliphatic carboxylic or polycarboxylic acid of at least 12C. CONSTITUTION:The metal-rolling oil is obtained employing at least one compound selected from the compounds prepared by the reaction between an alkylene oxide- added polyamine and at least one member selected from the group consisting of (a) an aliphatic carboxylic or polycarboxylic acid of at least 12C, (b) a polycarboxylic acid partial ester having in the molecule, at least one alkyl group of at least 11C and at least one remaining carboxyl group originated in the polycarboxylic acid and (c) a polycarboxylic (at least 4C) partial amide having in the molecule, at least one alkyl group of at least 11C and at least one remaining carboxylic group originated in the polycarboxylic acid. |
