って問題となり、この解消が求められている。<Prior Art> It is known to melt-extrude thermoplastic polyesters, such as polyethylene terephthalate or its copolymers, polyethylene naphthalate or its copolymers, or blends of these with small proportions of other resins, to form films. be. The resulting two-wheel stretched and heat-set polyester film has superior heat resistance, gas barrier properties, electrical properties, and chemical resistance compared to films made of other resins, and is therefore used in a variety of applications. However, polyester films are easily charged, but this charging property poses a problem depending on the application, and there is a need to solve this problem.
ポリエステルフィルムに帯電防止性を賦与する方法とし
て、従来から、種々の提案がされている。Conventionally, various proposals have been made as methods for imparting antistatic properties to polyester films.
その一つに、帯電防止能或は導電性を有する物質をポリ

しい、更にはまた上記添加剤のブリードアウトによる表
面の粘着性増加などの問題を克服することも至難である
、またブリード性にもムラが生じ易い等の問題がある。One of these methods is to add and blend a substance with antistatic ability or conductivity to the polymer in order to improve the overall and surface electrical conduction. However, although this method is certainly superior to the method of applying an antistatic agent to the surface in terms of the durability of the effect, on the other hand, it does not stain under the various heat conditions that occur when it is talled as a film. Furthermore, it is technically extremely difficult to suppress the deterioration of physical properties caused by mixing additives and to prevent surface defects from occurring due to poor compatibility.Furthermore, surface tackiness increases due to bleed-out of the additives mentioned above. It is extremely difficult to overcome these problems, and there are also problems such as uneven bleeding easily occurring.
他方、フィルムに直接帯電防止剤を少量塗布する方法が

ている。On the other hand, there is a method of applying a small amount of antistatic agent directly to the film, and although this method has the advantage of being simple, it has recently been avoided because its effect is temporary and it easily comes off. Research and development of antistatic agents has focused exclusively on the reaction crosslinking of conductive polymers or a portion thereof on the film surface, and various improvements have been made.

ある。However, with this method, the antistatic properties of the obtained film generally change depending on the environment, such as temperature and humidity, and this change is large, and the surface resistivity value is reduced to 1.
There is a problem in that it is difficult to reduce the resistance to 0.05Ω/mouth or less.
