Abstract
PURPOSE: To eliminate the corrosion of a head and also to improve orientation by making a magnetic coating alkaline by using specific 4-th class ammonium chloride, soap and a binder as a magnetic coating.
CONSTITUTION: As a charging inhibitor, a mixture of 4th-class ammonium chloride expressed I (R is any hydrocarbon radical of alkyl, aryl, etc., containing not less than one amide group; R1 to R3 are any hydrocarbon groups; X is anion of Cl, Br, I, SO4, PO4, etc.), soap expressed II (R is alkyl constituting fatty acid of C4W18; M is amine of less than C11 with only a C chaine in hydrophobic group), magnetic powder, nitrile butadiene rubber N, and vinyl chloride-vinyl acetate copolymer is kneaded. This magnetic coating using copolymer A plasticized rubber N as a binder is applied onto a base made of a high molecule material, thereby obtaining a magnetic recording medium.
