Title:
LUBRICANT COMPOSITION AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO2010109851
Kind Code:
A1
Abstract:
Disclosed is a novel lubricant composition which is useful as a material for a lubrication layer in a magnetic recording medium. The lubricant composition contains at least one compound represented by formula (1). In the formula, X represents a cyclic group which may be substituted; Y represents a single bond or a linkage group having a valency of 2 or more; at least one of X and Y represents at least one polar group such as a hydroxy group; Z represents a linkage group having a valency of 2 or more and composed of a carbon atom (C), a fluorine atom (F) and one or two arbitrary atoms (wherein a hydrogen atom is not taken into account); n represents a real number of 1 to 10; m represents a real number of 0 to 1; and s and t independently represent a real number of 1 or greater.
