どから文字、図面などが複写される。"Prior Art" In recent years, OHPs have come to be widely used for conferences, lectures, and educational purposes. For OHP use, transparent film originals of approximately A4 size are used, and characters, drawings, etc. from books, literature, documents, etc. are usually copied using an electronic copying machine or written on with an oil-based pen.

ーが脱落しやすい。When using an electronic copying machine, if untreated plastic film is used, the surface resistance of the film is too high, resulting in poor transfer of latent images from the media, resulting in poor reproduction of characters and drawings, or due to electrostatic charge. double feeding in the copier,
The problem arises that the film gets jammed. Furthermore, the adhesion of the toner to the film after development is insufficient and the toner is likely to fall off.
このため、フィルムの表面処理を行う方法が提案されて

For example, an organic solvent-soluble resin containing a matting agent is coated on a plastic film, and an antistatic agent is added to the surface of the coated layer. A method of adjusting the resistance value to 109 to IQISΩ has been used (Japanese Patent Publication No. 51-34734).

等のトラブルが発生する恐れのあることがわかった。However, there is still room for improvement in this film, for example, the surface slippage and blocking resistance of the coating layer are insufficient, and depending on the copying machine used, there is a risk of problems such as electrical transmission and film clogging. It turns out that there is.

As a result, they discovered that a film with excellent running properties in electronic copying machines could be obtained and completed the present invention.

・耐溶剤性にも優れるものである。That is, hydrophilic monomers and/or oligomers (prepolymers) undergo polymerization and crosslinking reactions when irradiated with ionizing radiation, forming a coating layer with a hydrophilic network structure having an appropriate crosslink density, and increasing water absorption capacity. It is presumed that it will have . Since the aqueous ink is quickly absorbed and retained within the hydrophilic network structure thus formed, it is considered that the aqueous ink has excellent recording properties (writing properties, fixing properties, drying properties). At this time, the presence of a hydrophilic solvent moderately suppresses the increase in crosslinking density, and furthermore, part or all of the hydrophilic solvent is instantly evaporated by irradiation with ionizing radiation, and at this time, the hydrophilic solvent is It is thought that recording performance is further improved because uniform micropores are formed in the film. In addition, since this coating film has a crosslinked structure, it also has excellent water resistance and solvent resistance.

It is 30 parts by weight. If it is less than 1 part by weight, the desired effect will hardly be obtained, and if it exceeds 100 parts by weight, the recording performance, transparency, water resistance, etc. of the aqueous ink will be deteriorated.

や紫外線が好ましく用いられる。In the method of the present invention, the coating layer of the coating composition formed as described above is cured by irradiation with ionizing radiation.
Examples of ionizing radiation include electron beams, ultraviolet rays, alpha rays, and beta rays.
Examples include rays, gamma rays, and X-rays. Since alpha rays, alpha rays, gamma rays, and X-rays are associated with the problem of danger to the human body, electron beams and ultraviolet rays are preferably used because they are easy to handle and are widely used industrially.

フィルムを劣化させる恐れがあるため好ましくない。When using an electron beam, the amount of electron beam irradiated is 0.1~
It is desirable to adjust within a range of about 2Q Mrad* O
If it is less than -I Mrad, sufficient irradiation effect cannot be obtained;
Irradiation exceeding 0 Mrad is not preferred because it may deteriorate some types of plastic films.

利点がある。Examples of electron beam irradiation methods include scanning method,
Curtain beam method, broad beam method, etc. are adopted, and the acceleration voltage when irradiating the electron beam is 100 to 300 kV.
The degree is appropriate. Incidentally, the electron beam irradiation method has the advantages of higher productivity than ultraviolet irradiation, no problem of odor or coloring caused by addition of a sensitizer, and moreover, it is easier to form a uniform crosslinked structure.
