MAGNETIC RECORDING MEDIUM |
| abstract |
A magnetic recording medium has a magnetic layer comprising a vinyl chloride copolymer acting as a binder and a magnetic powder formed on a non-magnetic medium. The vinyl chloride copolymer contains a hydroxyl group and a quaternary ammonium salt, wherein the above hydroxyl group is formed from a monoallyl- or monomethallyl-ether of a polyhydroxy compound or from a monoallyl- or monomethallyl -thioether of a polyhydroxy compound. |
