PURPOSE: To obtain a lubricant compsn. improved in storage properties and capacity stability by compounding a copper complex of N-acylated thiourea with a lubricant or a pressure medium. n CONSTITUTION: A libricant compsn. consists of a lubricant or a pressure medium (a) and at least one compd. (b) represented by formula. In the formula, X is 1 or 2 and, when X is 1, n is 2 and R is R 1 and, when X is 2, (n) is 1 and R is R 4 , R 1 is a 1-25C alkyl group or a 5-12C cycloalkyl group subsid. by a 1-8C alkyl group and R 2 and R 3 are a 1-18C alkyl group or a phenyl group and combined together with connected N to form a 5-7-membered heterocycle capable of containing N or O, R 4 is a 1-12C alkylene group which may be interrupted by at least one -O- group or a 2-12C alkenylene group which may be interrupted by at least one -Ogroup. n COPYRIGHT: (C)1992,JPO |
