The durability of a wire rope is improved. The wire rope includes a rope body having at least one strand each formed with a plurality of element wires twisted with each other; a lubricant interposed between the plurality of element wires of the at least one strand; and a resin layer coating the outer periphery of the rope body along with the lubricant, the lubricant containing a sulfur-containing organic molybdenum compound.

An antifriction coating formulation composition is disclosed. The antifriction coating formulation composition contains (a) a resin and (b) a metal sulfide containing molybdenum and cobalt, and optionally (c) a solid lubricant other than the metal sulfide and (d) a solvent. A coated film formed from the antifriction coating formulation composition provides better wear resistance as well as good coefficient of friction.
