Provided is a lubricant composition having small shear rate dependence of its apparent viscosity. The lubricant composition includes a perfluoropolyether as a base oil, and fluorine resin particles as a thickener. The lubricant composition further includes a fluorine-containing polymer having a tetrafluoroethylene structure under a state in which the polymer is dissolved in the perfluoropolyether.

A slide member is provided with a base material, a plated slide layer and an intermediate plated layer. The plated slide layer contains a solid lubricant. The intermediate plated layer is disposed between the base material and the plated slide layer, the intermediate plated layer increasing cohesion of the base material and the plated slide layer. The plated slide layer has a content of the solid lubricant in a range from 30 to 70 vol %, inclusive.

A fluorine-containing ether compound represented by a formula (1) shown below.
R.sup.4—CH.sub.2—R.sup.3—CH.sub.2—R.sup.2—CH.sub.2—R.sup.1—CH.sub.2—R.sup.2—CH.sub.2—R.sup.3—CH.sub.2—R.sup.5  (1) In formula (1), R.sup.1 and R.sup.3 represent the same or different perfluoropolyether chains, R.sup.2 represents a linking group containing at least one polar group, one or both of R.sup.4 and R.sup.5 represent a terminal group containing two or more polar groups, and R.sup.4 and R.sup.5 are different.

Fluoropolyether compounds that can be used as a lubricant, such as for magnetic recording media. The compounds have a terminal group that includes a phenol or benzene. The fluoropolyether compounds reduce the head to media distance while keeping comparable reliability in a hard disk drive compared to current industrial widely used fluoropolyether based lubricants.

An object of an aspect of the present invention is to provide: a lubricant excellent in adsorbability on the surface of a magnetic disk and in contamination resistance; and a magnetic disk which uses the lubricant and which is excellent in durability. The lubricant in accordance with an aspect of the present invention contains a fluoropolyether compound having, at a terminal thereof, a hydroxyalkenyl group or a hydroxyalkynyl group.

A laminate including a target, a coating film of a lubricant containing a paraffin wax and carbon fluoride formed on the target. The carbon fluoride is graphite fluoride having a proportion of 0.1 to 2.0% by mass relative to the paraffin wax. Further, an amount of the carbon fluoride in a vicinity of a target on which the coating film is formed is larger than an amount of the carbon fluoride on a surface opposite the target. Also disclosed is a method of coating a target as well as snow or ice sliding equipment.

The present invention relates to a composition suitable to be used as working fluid, said composition being in the form of a solution and comprising at least one (per)fluoropolyether polymer [polymer (P)] and at least one amorphous polymer [polymer (F)].

The invention provides a fullerene compound; a lubricant that is for a magnetic recording medium and that contains the fullerene compound; and a magnetic recording medium. The fullerene compound is an ionic liquid that is represented by general formula (1) and is formed from a Bronsted acid (H.sub.n1X) and a Bronsted base ([R.sub.2R.sub.3)N—].sub.m1—R.sub.1); wherein one of the Brønsted acid and the Broønsted base contains a group having a fullerene; and the other contains a perfluoroalkyl chain.
