Magnetic recording media comprising organosilicones in a magnetic layer thereof

摘要

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 organosilicone. The organosilicone is represented by the general formula +TR in which R represents a monovalent saturated or unsaturated hydrocarbon having 7 to 21 carbon atoms, R1, R2 and R3 independently represent a methyl or RCOO group, R4 is a saturated hydrocarbon group having 1 to 20 carbon atoms, and k, l, m and n are independently an integer provided that 1
