发明名称 MAGNETIC RECORDING MEDIUM
摘要 <p>A magnetic recording medium comprises a support the magnetic layer and a magnetic layer, coated on said support, comprising magnetic powder, a binder, (I) an ester compound having the formula: <IMAGE> (I) in which R1 and R2 are each a saturated alkyl group having 1 to 25 carbon atoms, branched or straight, the total carbon number of R1 and R2 being from 22 to 34, and R3 is a saturated or unsaturated alkyl group having 7 to 29 carbon atoms, branched or straight, and (II) an ester compound having the formula: <IMAGE> (II) in which R4 is an aliphatic hydrocarbon group having 1 to 29 carbon atoms, straight or branched, and R5 is an aliphatic hydrocarbon group having 1 to 23 carbon atoms, straight or branched, or a straight aliphatic hydrocarbon group having 24 to 36 carbon atoms, the total carbon number of R4 and R5 being 15 to 65. Alternatively, the ester (II) compound can be replaced by an aliphatic acid having from 8 to 30 carbon atoms. The magnetic layer comprising compounds (I) and (II) may also include an aliphatic acid having from 10-30 carbon atoms.</p>
