Abstract

NEW MATERIAL:A compound shown by formula I (n is 1, 2 or 3; R1 and R2 are H or hydrocarbon group; Rf is >=3C perfluoroalkyl). EXAMPLE:Nonadecafluorocarboxylic acid stearylamine salt. USE:A lubricant for magnetic recording medium, showing excellent lubricating properties under various use conditions. PREPARATION:A perfluoroalkylcarboxylic acid and an organic amine which are corresponding to a compound shown by the formula are reacted and recrystallized with a mixed solvent of Freon and petroleum ether to readily give the compound shown by the formula. When the compound shown by the formula is used as a lubricant for a magnetic recording medium having at least a magnetic layer on a non-magnetic substrate, the magnetic recording medium maintaining excellent lubricating properties under various use conditions, keeping lubricating effects for a long period having excellent running properties, wear resistance and durability is obtained.
