It is preferable to set to 1:10. That is, when the amount of the fluorine compound particles exceeds the above-mentioned ratio, the specific gravity of the composite particles becomes large and the composite particles easily precipitate. On the contrary, if the amount of the fluorine compound particles is less than the above ratio, the specific gravity of the composite particles tends to be small, and the particles tend to float easily.

組成物を得た。Example 3 3 parts of fluorinated pitch was dispersed in 197 parts of cresol and filtered through a wire mesh of 200 mesh, and while this filtrate was stirred with a disper, 15 parts of polyethylene wax was added to this solvent naphtha No. 2 85. To the parts was added a hot solution that had been heated and dissolved. Thus, mixed particles having polyethylene particles attached to the surfaces of the fluorine compound particles were produced. Then, 37.5 parts of the above-mentioned mixed particle dispersion liquid was added to 100 parts of a mixed solution of trishydroxyethyl isocyanurate (THEIC) / imide modified polyester paint (part of imide modified polyester paint), and a coating composition having a resin content of 5% Got

A 0 mm electric wire was produced. The coating film of this electric wire had a substantially good appearance, and the coefficient of static friction was as low as 0.05. Moreover, the separation of the composite particles as the lubricating component in the paint was not observed even after standing for 1 week.
