Abstract

PURPOSE:To form a lubricating film having good wear resistance and adhesiveness to a base material by constituting said film of a silane compd. contg. a fluorine-contg. org. group having a hydroxy group. CONSTITUTION:The fluorine-contg. org. group of the lubricating agent for a magnetic recording medium consisting of the silane compd. contg. the fluorine- contg. org. group contains the hydroxyl group. Such silane compd. is exemplified by compds. such as [HCF2CF2CH2OCH2CH(OH)CH2]2NCH2C-H2Si(OC3H7)3, [(CF3)2CFOCH2CH(OH)CH2 ]2NCH2CH2-N[ OCH2CH(OH)-CH2OCF(CF3)2 ](CH2)3 Si(-OCH3)3, C3F7OCF(CF3)CF2OCF(CF3)COOCH2CH(OH)-CH2O(CH2)2-Si(OCH3)3. The lubricating agent for the magnetic recording medium consisting of such silane compd. is crosslinked by bringing the hydroxyl group contained therein and a crosslinking agent into reaction, by which the wear resistance is improved.
