のである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electrostatic recording film, and in particular to an electrostatic recording film that directly converts an electrical signal into an electrostatic latent image and then develops it with toner to create a visible image. Regarding recording film. More specifically, the present invention relates to an electrostatic recording film used in electrostatic recording printers and plotters for CAD (interactive design) and the like.
絶縁性フィルム、導電層、誘電層をこの順に積層せしめ

すい欠点がめった。The electrostatic recording method, which is generally used in electrostatic plotters for CAD, applies a recording voltage to a multi-pin electrode head (hereinafter abbreviated as pin electrode), and creates micro-gaps between the pin electrode and the dielectric layer of the electrostatic recording film. An electrostatic latent image is formed on the surface of the dielectric layer by causing an air discharge in the gap (hereinafter abbreviated as gap),
This electrostatic latent image is then developed with liquid toner and fixed as a visible image. In order to obtain a stable image 1q, it is necessary to control the gap within an appropriate range from the Paschen curve, and for this purpose, for example, by adding particles and making the pin electrode contact a dielectric layer with appropriate irregularities. The most commonly used method is to properly control the gap. On the other hand, toner images on such electrostatic recording films are fixed without using heat or pressure, and simply by leaving them as they are, so conventional electrostatic recording films have sufficient fixing properties compared to electrostatic recording paper. Therefore, the toner image often peels off from the dielectric layer when it is touched or rubbed by hand.

定着性の良いものが得られにくく、実用化の大きな妨げ
になっていた。Electrostatic recording film has features such as recording stability, transparency, dimensional stability, strength, dust resistance, and storage stability compared to conventional electrostatic recording paper, so its development is desired. It has been difficult to obtain a method that stably provides high-quality images with high-speed recording and has good fixing properties, which has been a major hindrance to its practical application.

い。It is known that the dielectric layer of electrostatic recording paper requires an acrylic copolymer mixture to have a TO (glass transition temperature) within a specific range from the viewpoint of the balance between curl resistance and blocking resistance. (Tokuko Showa 57-1)
No. 9419 does not describe the relationship with fixing properties, nor does it describe the case of an electrostatic recording film.

とを見出し、本発明に到達したものである。The present inventors have conducted extensive studies on improving the fixing properties of toner images formed with liquid toner on electrostatic recording films, and have found that it has not been possible to satisfy both fixing properties and blocking properties with a single polymeric binder. Although it is difficult, there is an area where fixing and blocking properties can be balanced by combining polymer binders with different specific Tg, and this area does not necessarily match the case of paper-based electrostatic recording paper. However, they discovered that this is a region unique to electrostatic recording films, and arrived at the present invention.
