Crosslinking resins such as thermosetting resins are generally inexpensive and have good dimensional stability, melting resistance and chemical resistance, but when they are cured, they become brittle and cannot provide flexibility. In that respect, a thermosetting resin composition comprising a polyester resin and a curing agent thereof appropriately contains an aromatic component and an aliphatic component, and has flexibility even after curing, so that a film can be formed. is there. Further, this film also has a characteristic of a cross-linkable resin that is excellent in dimensional stability, melting resistance and chemical resistance. However, since it contains a large amount of aliphatic components, the flame resistance is essentially insufficient, and it is necessary to impart flame resistance.

That is, the thermosetting resin composition is pulverized into a powder, and the powder is evenly dispersed on the substrate. Then, the thermosetting resin composition melts and flows on the substrate and is substantially cured. This is a method in which the thermosetting resin composition is melted and crosslinked to form a film by heat treatment at a temperature at which reaction is possible or higher, and the base material and the film are separated to obtain a thermosetting film. In practice, the thermosetting resin composition is preferably pulverized to have a particle size of 50 μm or less, more preferably 30 μm.
It is better to be m or less. If it is larger than this, the film surface becomes rough and smoothness may be impaired. For pulverization, it is preferable to pulverize a thermosetting resin composition that has been sufficiently cooled and solidified with a ball mill because a uniform powder can be obtained.

Next, the application of the thermosetting resin composition onto the substrate may be carried out by uniformly applying the pulverized powder of the thermosetting resin composition onto the substrate such as metal or resin. However, more preferably, a method of charging static electricity to the powder of the crushed thermosetting resin composition, spraying this on a metal plate, and adsorbing the powder to the surface of the plate by the action of static electricity is simple and Can be done uniformly. Moreover, since the adsorption is performed by static electricity, the powder of the thermosetting resin composition can be adsorbed to an arbitrary shape having an arbitrary thickness, and thus a thermosetting film having an arbitrary shape can be produced. . Further, the thickness of the film can be easily controlled by adjusting the amount of the thermosetting resin composition dispersed on the substrate. The surface of the metal plate is preferably treated with a fluorine-based or silicon-based release agent in order to improve the separability of the film.

The present invention is a polyester thermosetting film which is inexpensive and excellent in flexibility, dimensional stability, fusion resistance, chemical resistance, etc., but has a problem of poor flame resistance. A polyester resin, which is a hydroxyl group, and an organic phosphorus compound having two or more hydroxyl groups as functional groups, are cured by using a curing agent that reacts with the hydroxyl group, and thus consist of three components: a polyester resin, an organic phosphorus compound, and a curing agent. Flame resistance is imparted by creating a three-dimensional crosslinked structure and introducing phosphorus atoms into the film. Since this organic phosphorus compound has an aliphatic skeleton, it does not impair the flexibility of the film even if it is introduced into the crosslinked structure, and it decomposes during flame contact to form a non-volatile phosphoric acid. By forming a protective film, and promoting the carbonization of the organic substance by the dehydrating action of the generated phosphoric acid to form a carbonized film, and blocking the supply of oxygen, flame resistance is exhibited.
