Magnetic recording medium |
| abstract |
A magnetic recording medium having a magnetic layer on one surface of a nonmagnetic support and a back coat layer on the other surface, wherein the back coat layer contains two kinds of carbon black having different average particle sizes and a binder containing two kinds of copolymer. One of the copolymers is copolymer A comprising vinyl chloride, alkylcarboxylic acid/vinyl ester and vinyl alcohol and having an average degree of polymerisation of 300 to 600, and the other is copolymer B further containing an amino group and having an average degree of polymerisation of 200 to 800. The present invention accomplishes a magnetic recording medium having a back coat layer having an excellent surface property, high electromagnetic conversion characteristics, high travel stability and high travel durability. |
