MAGNETAUFZEICHNUNGSMEDIUM MIT EINER EIN SPEZIFISCHES GLEITMITTEL ENTHALTENDEN RUECKUEBERZUGSSCHICHT

摘要

A magnetic recording medium comprising a back coat layer formed on a non-magnetic support on one side which is opposite to a side where a magnetic recording layer is formed. The back coat layer is made of a dispersion of a fluorine-modified organosiloxane in a binder resin. The organosiloxane is of the following formula (A) in which R1 represents a saturated or unsaturated monohydrocarbon group having from 7 to 21 carbon atoms, R2 represents a saturated monohydrocarbon group having from 1 to 4 carbon atoms, k is an integer of from 1 to 12, l is an integer of from 2 to 6, m is an integer of 1 or 2, n is an integer of 1 or 2 provided that m+n
