。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electrostatic recording medium, and more particularly to an electrostatic recording medium that can provide clear recording without streaks, scumming, etc.

方式が主流である。(Prior art) Electrostatic recording has traditionally been used as a high-speed recording method in facsimiles, printers, etc., but in recent years, CAD, which uses computers to perform design and drawing, has become popular.
An electrostatic printer/electrostatic plotter is used for the output of the system. In the conventional record based on text, 2
About OO dots/inch was sufficient, but such CA
For outputting drawings such as the D system, high-resolution recording of approximately 400 dots/inch and minimal staining are required. Incidentally, many of the drawings output from the CAD system are wide, and in order to achieve uniform development, liquid development is the mainstream.

ため、従来の文章記録では見過ごされていた僅かな汚れ
の発生にだいしても改良を要求されているのが現状であ
る。In the liquid development method, the toner particles are finer than in the powder development method, so in the electrostatic recording method, in addition to the latent image for the recorded image, even a low potential charge generated by friction etc. tends to appear as dirt. However, in records such as drawings, there is a possibility that such stains may be mistaken for changes in the design, so improvements are required even if the slight stains that occur are overlooked in conventional written records. is the current situation.

に低画像濃度で記録されることをいう。Such stains include streaks and background stains on the white paper area, but streaks are the stains that occur when the electrostatic recording medium is rubbed by a slight convexity on a part of the edge of the recording electrode. This refers to a phenomenon in which only a portion is triboelectrically charged and appears as streak-like stains after development.These streaks often reach a length of several meters or more, and electrostatic recording materials for CAD are particularly required to be free of streaks. Background smearing is a phenomenon also called Capri, in which the entire surface of an electrostatic recording medium is charged to a low potential, and after it is developed with toner, even the blank areas where there is no recording are recorded with a low image density. say.
従来、地lηれに対しては静電記録体の裏面を導電処理
して汚れの原因である低電位の電荷を逃がすことにより
対処してきたが、かかる方法だけでは現在の高い要求レ
ベルを満たすことがとうてい出来ないのが現状である。Conventionally, grounding has been dealt with by conducting conductive treatment on the back side of the electrostatic recording medium to release the low-potential charges that cause stains, but this method alone cannot meet the current high requirements. The current situation is that this is simply not possible.

囲で調製される。(Function) The antistatic agents used in the present invention include polyoxyethylene ethers such as polyoxyethylene alkyl ether and polyoxyethylene alkylphenyl ether, which are nonionic antistatic agents, polyoxyethylene stearate, and polyoxyethylene stearate. These include polyoxyethylene derivatives such as fatty acid esters of polyoxyethylene such as ethylene stearate, various derivatives of polyoxypropylene, or copolymers of both, glycerides such as glycerol laurylate and glycerol stearate, and cationic antistatic agents. Examples include alkyltrimethylammonium chloride, polyoxyethylene alkylamine, alkylamine acetate, etc., anionic antistatic agents include sodium alkylbenzenesulfonate, sodium fatty acid, etc., and amphoteric antistatic agents include alkylbetaine, alkylglycine, etc. etc. are exemplified. Among the above antistatic agents, especially nonionic antistatic agents, when a dielectric layer is formed by coating a solvent-based paint, they are easily dissolved or uniformly dispersed in the dielectric layer paint, or are easily dispersed on the dielectric layer. It is more preferably used because it can be applied uniformly. Furthermore, if a hydrophobic group or a hydrophobic polymer chain is further introduced into the above-mentioned nonionic or ionic antistatic agent, it can be uniformly dispersed or dissolved in a solvent-based dielectric layer coating, or it can be applied uniformly on a dielectric layer. more preferable. If the content of the antistatic agent is too low, there will be no stain improvement effect, while if it is too high, the density of the recorded image will decrease, so the content should be 1.0×.
It is prepared in the range of 10-3 to 5.0 x 10-'g/m2, more preferably 5.0 x 10-'' to 2.0xlO-'g/m2.

る白抜けが発生する欠点がある。Polymer electrolytes, typified by conductive agents used to impart conductivity to the support of electrostatic recording materials, have 20 to 100 monomers containing anions or cations, and have hydrophilic properties. It is very strong and has a molecular weight of several thousand or more, so it cannot be uniformly dispersed in a solvent-based dielectric layer paint, and even if it is coated on a dielectric layer, it cannot be applied uniformly. For this reason, when a polymer electrolyte is used, there is a drawback that a portion is created where the charge for image recording is lost, resulting in so-called white spots in the recorded image.

方法等が例示される。In the present invention, the presence of an antistatic agent in or on the dielectric layer means to include the antistatic agent in the dielectric layer or to form a layer containing the antistatic agent on the dielectric layer. Although the method is not particularly limited,
A method in which an antistatic agent is dissolved or dispersed in a dielectric layer paint, which is usually a container type, using a stirrer or an attritor, and then applied to a conductive support using a bar coater, or a paint containing an antistatic agent is applied statically. Examples include a method of coating the dielectric layer of the electrical recording material using a bar coater or the like, or a method of spraying it.
