Abstract
Magnetic recording media are described which comprise a support having a magnetic recording layer thereon. The magnetic recording layer is made of a dispersion of magnetic particles in a binder and a specific type of fatty acid-modified, fluorinated organosilicone. The organosilicone is represented by the general formula ##STR1## in which R.sub.1 represents a monovalent saturated or unsaturated hydrocarbon having 7 to 21 carbon atoms, R.sub.2 represents a methyl or phenyl group, each R.sub.3 represents a OCOR.sub.1 in which R.sub.1 has the same meaning as defined above, Y represents --CF.sub.3 or --(CF.sub.2)--.sub.k W in which k is an integer of from 1 to 8, and W is hydrogen or fluorine, and l, m and n are independently an integer provided that 0.ltoreq.l<200, 1.ltoreq.m<100, 1.ltoreq.n<100, and l+m+n.ltoreq.300.
