PROBLEM TO BE SOLVED: To obtain a lubricating material capable of operating coating, dipping and spraying, etc., by using a usual organic solvent, and useful for magnetic tapes and mild to the environment by containing a specific alkylene oxide derivative. SOLUTION: This lubricating material contains (A) 1 mole of an alkylene oxide derivative having an alkylene oxide group and an ester group or an ammonium group in a molecule and expressed by formula I-IV [R1 is H or a 1-26C monovalent hydrocarbon; R2 is a 1-6C divalent hydrocarbon; R3 is a 1-26C monovalent hydrocarbon or hydrogen fluoride group; (m) is 1-12] and preferably (B) 0.01-100 mole of an aliphatic amine of the formula R5 N(R6 )R7 (R5 is a 1-26C monovalent hydrocarbon; R6 and R7 are each H or a 1-26C monovalent hydrocarbon). |
