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

摘要

PROBLEM TO BE SOLVED: To obtain a lubricant for recording media retaining excellent lubricity under various application conditions, maintaining lubricant effect for a long time and having excellent tracking ability, abrasion resistance, durability and the like. SOLUTION: For example, a CF3COOH(CH3)2NC2H4OOC-Rf-COOC2H4N(CH 3)2HOOCCF3 (Rf expresses a fluoropolyether group having 2,000 average molecular weight) is used as the lubricant for magnetic recording media.
