LUBRICANT FOR MAGNETIC RECORDING MEDIUM, AND METHOD FOR PRODUCING MAGNETIC RECORDING MEDIUM

Provided is a lubricant for a magnetic recording medium, the lubricant being able to form a lubricating layer having excellent adhesion to a protective layer. The lubricant for a magnetic recording medium contains a fluorinated ether compound in which a group having an ethylenic carbon-carbon double bond is disposed at one or both terminals of a perfluoroalkyl polyether chain. It is preferable forthe group having an ethylenic carbon-carbon double bond to be disposed at one terminal of the perfluoroalkyl polyether chain and for a hydroxyl group to be disposed at the other terminal. It is preferable for the lubricant to contain a compound which has one or a plurality of one or more types of functional group selected from among hydroxyl groups, amino groups, amido groups and carboxyl groupsat one or both terminals of a perfluoroalkyl polyether chain. 本发明提供能够形成与保护层的密合性优异的润滑层的磁记录介质用润滑剂。所述磁记录介质用润滑剂包含含氟醚化合物，上述含氟醚化合物在全氟烷基聚醚链的一个或两个末端配置有具有烯属碳-碳双键的基团。优选在上述全氟烷基聚醚链的一个末端配置有上述具有烯属碳-碳双键的基团，在另一个末端配置有羟基。优选包含在全氟烷基聚醚链的一个或两个末端具有1
