PERFLUOROPOLYALKYL ETHER-BASED COMPOUND, LUBRICANT COMPRISING THE SAME, AND RECORDING MEDIUM USING THE LUBRICANT

摘要

PROBLEM TO BE SOLVED: To provide a lubricant for recording media which retain high lubricity under various service conditions, sustain high lubricant effect over a long time, and have excellent travelability, abrasion resistance, durability, etc. SOLUTION: This lubricant to be used for magnetic recording media is e.g. C18H37-CH(CH2COO.H3NC18H37)COO-Rf-OCOCH(CH2COO.H3NC18H37)-C18H 37 (Rf is a fluoropolyether group 2,000 in average molecular weight).
