Magnetic recording media |
| abstract |
(57) [PROBLEMS] To provide a magnetic recording medium excellent in durability and electromagnetic conversion characteristics, which is provided with a lower coating layer containing a binder having excellent dispersibility and durability. In a magnetic recording medium, a lower coating layer having a non-magnetic powder or a ferromagnetic powder dispersed in a binder and an upper magnetic layer having a ferromagnetic powder dispersed in a binder are provided on a non-magnetic support. The binder of the coating layer is composed of polyurethane resin which is a reaction product of diol and organic diisocyanate as a main raw material, and the short chain diol having a cyclic structure is contained in the polyurethane resin in an amount of 17 to 40% by weight. , Ether group 1.0-5.0m A magnetic recording medium containing 10 to 50% by weight of a long-chain diol containing mol / g in a polyurethane resin. |
