However, in the above method, it is difficult to adjust the coating amount and uneven coating is likely to occur. In addition, there is a problem in that when the material is adhered to another material after the application, the adhesiveness is lowered and the adhesion is difficult. In the above method, the coating process is complicated and it is difficult to use it for a material having low heat resistance. Further, there is a problem that the above-mentioned lubricating resin coating material penetrates into the coating material, and the heat resistance of the coating material is lowered. Also,
There is also a problem that the adhesiveness with other materials is significantly reduced after application. The above-mentioned method is good because the fluorine-based resin diffuses in an island shape on the surface of the coating material, so that both lubricity and adhesiveness can be balanced. However, there is a problem that the lubricity tends to vary.

That is, the polyethylene particles have a particle size of 5 μm.
When it exceeds m, the film is repelled and the appearance is deteriorated. On the other hand, if the melting point is less than 95 ° C, the strength is lowered and the polyethylene particles are easily detached from the film, so that the lubricity cannot be maintained. On the contrary, when the melting point exceeds 115 ° C., the adhesiveness with the imide group-containing polymer precursor is deteriorated, and the polyethylene particles are peeled off and the lubricity cannot be maintained. Furthermore, the molecular weight is 30
If it is less than 00, the polyethylene particles tend to aggregate and the coating becomes extremely non-uniform, and if the molecular weight exceeds 7,000, the adhesiveness with the imide group-containing polymer precursor decreases, and the polyethylene particles easily peel off to maintain the lubricity.
