    摘要： Provided is a mixed powder for powder metallurgy that contains a readily available compound as a lubricant, does not need to contain a stain-causing metal soap, has excellent ejection properties, and can exhibit excellent fluidity without deteriorating the ejection properties even in the case of further containing carbon black. The mixed powder for powder metallurgy contains (a) an iron-based powder and (b) a lubricant, where the lubricant (b) contains a specific aliphatic amine.

    摘要： In a magnetic recording medium, dimethylamino alkylester alkylcarboxylate is held in a magnetic layer. This dimethylamino alkylester alkylcarboxylate has an excellent lubrication function under severe conditions such as a high-temperature and high-humidity condition or a low-temperature and low-humidity condition, and considerably reduces the friction coefficient of an object to be treated. The lubrication performance of dimethylamino alkylester alkylcarboxylate is sufficiently maintained even after dimethylamino alkylester alkylcarboxylate is held under the high-temperature and high-humidity condition, and is very stable. Therefore, when such dimethylamino alkylester alkylcarboxylate is held in, e.g., the magnetic layer of a magnetic recording medium, a magnetic recording medium which is excellent in abrasion resistance, durability, and travelling performance can be obtained.
