| Abstract | A magnetic recording medium having a magnetic layer on one surface of a substrate and a back layer on the other surface, which is characterized by that the back layer is that formed by dispering a filler such as carbon black, graphite, SiO2, TiO2, Al2O3,Cr2O3, SiC, CeO2, CaCO3, zinc oxide, geothite, afe2O3, talc, kaolin, CaSO4, boron nitride, Teflon powder, graphite fluo ride, molybdenum disulfide, zirconia etc. In a binder containing a radiation sensitive curable resin such as acryl-modified vinyl chloride vinyl acetate vinyl alcohol copolymer, acryl-modified polyurethane elasto mer, acryl-modified polyester resin, etc. and curing it prior to rolling. The obtained back layer is very tough and can reduce the number of dropouts. |
