PROBLEM TO BE SOLVED: To provide a grease composition for use in resin lubrication which improves the lubrication state of resins against resins, or resins against different materials such as metals. SOLUTION: This grease composition for use in resin lubrication is produced by incorporating a saturated or unsaturated fatty acid, and/or a fatty acid metal salt into a grease base material containing a base oil and a thickener excluding a fatty acid metal salt thickener. Carbon atoms of the saturated or unsaturated fatty acid are preferably 8-22. The fatty acid metal salt is a metal salt of a linear saturated fatty acid having 8-14 carbon atoms, or a metal salt of an unsaturated fatty acid, the number of an unsaturated group of which is 1-4, having 16-22 carbon atoms, and the metal has preferably 1-4 valence. The saturated or unsaturated fatty acid, and/or the fatty acid metal salt are used singly or in combination. COPYRIGHT: (C)2010,JPO&INPIT |
