| titleOfInvention | Magnetic recording medium |
| abstract | The present invention provides a magnetic recording medium having high dispersibility of ferromagnetic powder, excellent electromagnetic conversion characteristics, running properties, storage stability at high temperatures, and still durability. A material having a magnetic layer in which at least one ferromagnetic powder and a binder are dispersed directly on a support or on which a binder of the magnetic layer contains a polyester polyol, a chain extender, and an organic diisocyanate is provided on a support. A polyurethane obtained by reacting, the ferromagnetic powder is a ferromagnetic powder containing cobalt-containing iron as a main component and yttrium, and the polyurethane contains an aliphatic dibasic acid in a polyester polyol, and a diol component Is composed of an aliphatic diol component having an alkyl branched side chain and no cyclic structure, the chain extender is composed of an aliphatic diol having an alkyl branched side chain, and the lower layer binder is cyclic with a polyol having an ether group in the polyurethane. A magnetic recording medium comprising a chain extender comprising a diol having a structure and an organic diisocyanate. [Selection figure] None |
