Description of the Related Art In recent years, magnetic prepaid cards used for telephone cards, vehicle cards, shopping cards, etc. are often forged or altered and used, which is a big social problem. Therefore, as a substitute for the magnetic type prepaid card, a card using an IC having an excellent security function has come into the spotlight. The amount of IC modules used for such purposes has been increasing in recent years. Carriers made of paper or plastic are used to carry IC chips, especially those without lead wires. That is, the IC chip is inserted into the carrier and sealed with a cover tape so as not to pop out, and then transported or stored. In this carrier tape method, there is a possibility that static electricity of tens of thousands of volts may be generated when the adhesive cover film is peeled off. Particularly when the carrier is a plastic film, there is a problem that static electricity due to tape peeling adversely affects the IC chip.

A polyester film having excellent electric properties, particularly a film made of polyethylene terephthalate or polyethylene naphthalate, has been used or studied, but such a polyester film has a drawback that it is easily charged.
When the film is charged, dust and dirt are attached to the surface of the film, which causes quality problems. Further, when an organic solvent is used in the film processing step, there is a danger of ignition due to discharge from the charged film.

As the antistatic agent to be contained in the antistatic coating film, a low molecular type and a high molecular type are known, but each has its advantages and disadvantages. Therefore, the antistatic agent is properly used depending on its characteristics. For example, as a low molecular type antistatic agent, a surfactant type anionic antistatic agent such as a long-chain alkyl compound having a sulfonate group (JP-A-4-28728) is known, Further, as a high molecular type antistatic agent, a polymer having an ionized nitrogen element in its main chain (Japanese Patent Application Laid-Open No. 3-25
5139, JP-A-4-288127, JP-A-6-320390), sulfonate-modified polystyrene (JP-A-5-320394), and the like are known.

However, there is a problem that the antistatic property (antistatic property) decreases with time. On the other hand, in the antistatic coating film using a polymer type antistatic agent, it is necessary to add a large amount of antistatic agent in order to obtain good antistatic property. Is not economical because it is necessary to form In addition, when a waste film that has not become a product (for example, a film end portion cut and removed in the manufacturing process) is collected and used as a recycled material for film production, it is included in the recycled material during melt film formation. There arises a problem that the coating film components are thermally deteriorated, the obtained film is markedly colored and lacks in practicality (recovery is poor). Further, defects such as difficulty in peeling the films from each other (blocking) and easy shaving of the coating film occur, and their solution is desired.
