Abstract A thermosetting resin composition formed of a polyaminobismaleimide resin, which is composed of a bismaleimide compound and a diamine compound, and a solid lubricant. The composition has low coefficient of friction and excellent wear resistance, and can be utilized for self-lubricating parts. The thermosetting resin composition of the instant invention comprises 100 parts by weight of a polyaminobismaleimide resin composed of a bismaleimide compound represented by the following general formula (I): Image (I) wherein R1 means a divalent group of Image or Image , and X denotes a direct bond or a group selected from divalent hydrocarbon group having 1-10 carbon atoms, hexafluorinated isopropylidene group, carbonyl group, thio group, sulfinyl group, sulfonyl group and oxo group, and a diamine compound represented by the following general formula (II): Image (II) wherein R2 means a divalent group of Image or Image , and X denotes a direct bond or a group selected from divalent hydrocarbon group having 1 10 carbon atoms, hexafluorinated isopropylidene group, carbonyl group, thio group, sulfinyl group, sulfonyl group and oxo group; and 5-200 parts by weight of a solid lubricant.
