More Information
Summary:A lubricant composition comprising (A) a compound of the formula: R1-COO-R2 wherein R1 is a higher aliphatic hydrocarbon residue and R2 is an aliphatic hydrocarbon residue which may contain fluorine atom(s) and/or oxygen atom(s), and (B) a compound of the formula: wherein R3 is a higher aliphatic hydrocarbon residue; R4 and R5 are independently a hydrogen atom or an aliphatic hydrocarbon residue which may contain fluorine atom(s) and/or oxygen atom(s), gives a lubricant layer in a magnetic recording medium having good running durability, still life and weather resistance.
