    摘要: PROBLEM TO BE SOLVED: To provide a lubricant, particularly a lubricant for magnetic recording medium in which excellent lubricating ability is kept under various use conditions and lubricating effect is retained even in long-time use.
    SOLUTION: The lubricant is obtained by mixing at least one compound selected from compounds represented by general formula (a) (wherein R
    1 , R
    2 , R
    3 and R
    4 are each hydrogen, an aliphatic alkyl group or an aliphatic alkenyl group and at least either one of R
    1 and R
    2 is hydrogen and at least either one of R
    3 and R
    4 is hydrogen; m is an integer of 1-6 and n is an integer of 1-5 and p and q are each an integer of 0-30 and r is an integer of 1-12) with at least one compound selected from compounds represented by general formula (b) (wherein R
    5 and R
    6 are each an aliphatic alkyl group or an aliphatic alkenyl group; x is an integer of 1-6 and y is an integer of 1-5 and s and t are each an integer of 0-30 and u is an integer of 1-12) and general formula (c) (wherein R
    7 is a fluoroalkyl group, a fluoroalkenyl group, a fluoroether group or a fluoropolyether and R
    8 is an aliphatic alkyl group or an aliphatic alkenyl group and a is an integer of 1-12) and preferably further mixing the mixture with a compound represented by general formula (d) (wherein R
    9 and R
    10 are each hydrogen, an aliphatic alkyl group or an aliphatic alkenyl group; b is an integer of 1-12; v is an integer of 1-12; w is an integer of 1-6; z is an integer of 1-5; h and k are each an integer of 0-30). The lubricant is used to form a lubricant layer of a magnetic recording medium.
