Abstract
To provide a lubricant for recording medium, which is advantageous not only in that it maintains excellent lubricity under various conditions for use and excellent lubricating effect over a long time, but also in that it can impart excellent transport properties and excellent abrasion resistance as well as excellent durability. For example, when C18H37—CH(CH2COOC10H6OH)COORf (wherein Rf represents a saturated or unsaturated partially-fluorinated-alkyl group) is used as a lubricant for magnetic recording medium, there can be obtained a magnetic recording medium having excellent transport properties and excellent abrasion resistance as well as excellent durability.
