用に供し難い。However, general polyester films have the disadvantage that although they have a high degree of electrical insulation, they tend to generate and accumulate static electricity, causing problems due to static electricity. For example, during film forming processes such as culmming, printing, adhesion, bag making and packaging, and other secondary processing processes, there may be problems with low work efficiency such as wrapping around rolls, injury to the human body, and difficulty in handling. The occurrence of dirt and contamination on the film surface result in a low product value. As methods for preventing such electrostatic damage, there are two methods: - A method of kneading an antistatic agent into a resin to form a film, and a method of applying an antistatic agent to the surface of the film. In contrast, this so-called kneading-type band core prevention treatment method achieves the antistatic effect by seeping the antistatic agent from inside the film to the surface, whereas the polyester resin has a high secondary transition. Due to the temperature, the antistatic agent does not ooze out onto the film surface at temperatures around room temperature after film formation. Due to the high reactivity of the polymer, it has been difficult to incorporate antistatic effects into the film to avoid deterioration of the polymer during film formation, coloring, and deterioration of physical properties. In particular, in the case of a biaxially stretched polyester film, the antistatic 11. Completely anti-static due to the dissipation and dissipation of the agent
In many cases, the antistatic agent no longer exhibits any antistatic effect (furthermore, many antistatic agents, depending on the formulation of the polyester film,
This extremely reduces the transparency of the film, making it difficult to put it to practical use.

に供し難い状態を惹起する。Furthermore, as a method for applying an antistatic effect to the film surface, for example, Japanese Patent Publication No. 50-6867 discloses an antistatic finishing method in which an antistatic agent is applied as an aqueous solution; The coated layer of polyester film that has been coated will turn white and its transparency will decrease due to a sudden change in temperature and humidity, for example, from an atmosphere of 50% relative humidity at 23°C to an atmosphere of 80% relative humidity at 60°C. , causing a situation that is difficult to put into practical use.

Sulfuric acid and sulfonic acid derivatives such as Na salts of higher alcohol succinic acid esters having an alkyl group of ilo to 20, sulfuric acid ester salts of alkyl phenylene oxide adducts, alkyl sulfonates, and alkylaryl sulfonic acids are preferred. . In addition, as a lower ether glycol,
Ethylene glycol ethyl ether Ethylene glycol butyl ether and ethylene glycol butyl ether are preferable when mixed with water in a given ratio.When made into a coating solution, higher ether glycols cause layer separation from water and cause problems such as uneven coating during coating. This is not desirable as it can easily occur.

It is essential to account for @% or more. Preferably 60

If it is less than %, the surface tension of the coating solution increases, the wettability to the film decreases, and coating spots are likely to occur.
Furthermore, for unknown reasons, when a sudden change in temperature and humidity occurs, the transparency of the film decreases, making it difficult to put it to practical use.

層の密着性が良好である効果が付与される。The polyester film used in the present invention is a melt-extruded unstretched film, a uniaxially stretched film,
Alternatively, either biaxially stretched film may be used, but since the film is wide and the film travels at a high speed, it is difficult to apply it uniformly. In addition, since the former two are subjected to stretching heat treatment after coating, the effect of good adhesion between the antistatic layer and the base layer is imparted.

If the IR is less than 0.005 g/j, the antistatic effect will be weakened. Furthermore, if the coating density exceeds 0.5 g/j, the film will have low transparency and poor blocking properties.

All four have good properties in terms of anti-static properties.
Scraps. However, if the antistatic agent is outside the scope of the present invention, the antistatic effect cannot be obtained in one minute. (
Comparative Examples 1 to 3) It can be seen that the addition of lower ether gellicol, which is outside the scope of the present invention, results in a decrease in transparency when subjected to rapid changes in temperature and humidity. (Comparative Examples 4 to 5) Margins (Effects of the Invention) The polyester film of the present invention exhibits good antistatic properties at low humidity, and does not change haze even with sudden changes in temperature and humidity.
It is clear that this antistatic film is extremely useful for packaging, industrial use, and other uses.
