Abstract
It is an object of the present invention to provide a practical lubricant composition excellent in wear resistance, extreme pressure properties and low friction properties for mechanical friction sliding members. The lubricant composition contains, as a major ingredient, a compound of formula (1), preferably a compound of triazine structure:(R—X—)m—D  (1) wherein D is a heterocyclic residue of a 5- to 7-membered cyclic structure positioned at the center of the molecule, or a compound residue of cyclic structure with m radiating side chains; X is a single bond, a group represented by NR1 (wherein R1 is an alkyl group having a carbon number of 1 to 30 or a hydrogen atom), an oxygen atom, a sulfur atom, a carbonyl group, a sulfonyl group, or a combination thereof forming a divalent coupling group; R is an alkyl, alkenyl, alkynyl, aryl or heterocyclic group; and m is an integer from 3 to 11.
