覆方法に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention improves the clarity of colors during projection of a transparent copying film produced by an electrophotographic copying machine, etc., and improves storage stability. The present invention relates to an image covering method for the purpose of

現在、電子写真複写法や静電印刷法などで透明フィルム

どによりスクリーン上に投影することは広く行われてい
る。(Prior art) Currently, a transparent copying film is produced by forming two images of characters using toner on a transparent film using an electrophotographic copying method or an electrostatic printing method, and this is projected onto a screen using an overhead projector or the like. It is widely practiced.
そして従来はトナーとしては黒色系のものが使用される
にすぎなかったが、近年黒色系以外のを彩色（カラー）
で文字３画像を形成することが広く行われるようになっ
てきた。In the past, only black toners were used, but in recent years, toners other than black have been colored.
It has become widely used to form three character images.

、所望のカラー色にならず黒灰色化することがしばしば
認められ大きな問題となっている。If the toner is black, there will be no particular problem when it is projected onto a screen, but when a translucent copying film on which two images of characters are formed using color toner is projected onto a screen using an overhead projector. However, it is often observed that the desired color is not achieved and the color becomes blackish gray, which is a big problem.
このようにトナーのカラー色が投影時黒灰色化する原因
としては、トナーそのものの透明性不足。The reason why the toner color turns black and gray when projected is the lack of transparency of the toner itself.
トナー表面に凹凸があるために光が散乱ないし乱反射し
てトナ一部における光の透過量が減少して。The unevenness of the toner surface causes light to be scattered or reflected diffusely, reducing the amount of light transmitted through a portion of the toner.
スクリーン上まで到達せずに鮮明なカラー色が得られず
黒灰色化するものと考えられる。It is thought that the color does not reach the top of the screen and clear colors cannot be obtained, resulting in a black-gray color.

ルの間を通してトナー画像部を加熱、加圧する方法が提
案されている。Several methods have been proposed to solve the above problems. For example, there is a method to improve the binder, dye, pigment, etc. contained in the toner in order to improve the transparency of the toner itself.
A method has been proposed in which the toner image area is heated and pressurized through the space between the toner images.
しかしロールで直接加熱、加圧する方法では加熱温度が
少しでも高すぎるとトナ一部がロールにとられるという

のままロールで加熱、加圧することによる問題点を解決
する方法として。However, in the method of directly heating and pressurizing the toner with a roll, a problem arises in that if the heating temperature is even slightly too high, a portion of the toner will be taken up by the roll. Therefore, as a method to solve the problems caused by heating and pressurizing this transparent copying film as it is with a roll.

ィルムを剥離する方法が提案されている。JP-A No. 61-36762 proposes a method in which a thin film (cover film) is superimposed on the surface of the toner image area of a transparent copying film, heated and pressurized, and then the cover film is peeled off. .

問題点がある。(Problem to be Solved by the Invention) However, in the method of using this cover film, when the cover film is peeled off after the films are overlapped and heated and pressurized, a portion of the toner may be removed from the surface of the cover film. In some cases, even if the surface of some toners is smooth, when they are stacked and stored, the surface of some toners may be scratched, or in extreme cases, some toners may fall off. There is a problem that long-term storage stability is poor.
本発明はこのようなトナー画像部表面を平滑化しようと

る。The present invention provides a method for solving the problems that occur when attempting to smooth the surface of a toner image area and improving the storage stability of a translucent copying film.

樹脂が冷却後。(Means for Solving the Problem) That is, the present invention, after forming a toner image on a transparent film, applies a cover sheet composed of a film and/or a mold release agent layer/thermoplastic transparent resin layer to the transparent film. The thermoplastic transparent resin layer surface of the cover sheet is superimposed on the toner image surface, heated and pressed with a roller or temporarily, and after the thermoplastic transparent resin has cooled.

ムの厚さも熱伝導率を良くするためにはできる限り薄く
するのが望ましいが、一方力バー用シートを加工する際
および使用時には強度、剛性も必要であるので薄くなり
すぎるのも好ましくない。A film and/or paper is used for the cover sheet 1 shown in FIG. Although it is desirable to make the sheet as thin as possible in order to improve thermal conductivity, it is also undesirable to make it too thin since strength and rigidity are also required when processing and using the force bar sheet.

２通常は数μ以下の厚さで使用される。３に使用される
熱可塑性透明樹脂としては加熱、加圧された際、溶融し
、透光性複写フィルムに融着固化する樹脂で。Therefore, as a film, a polyethylene terephthalate film having a thickness of about 9 μm to 50 μm, which is relatively inexpensive and has excellent strength and rigidity, is useful. In addition, as the mold release agent used in 2, various types can be used, but 1 silicone-based, fluorine-based, and cellulose-based mold release agents are usually used, and the thickness should be made as thin as possible. It is desirable that the thickness of the film be less than 2 microns. The thermoplastic transparent resin used in No. 3 is a resin that melts when heated and pressurized and is fused and solidified to the translucent copying film.

厚さとしては通常は２０μ以下、望ましくは１０μ以下
の状態で使用される。The softening point or melting point of the thermoplastic transparent resin needs to be higher than the softening point of the toner binder, but if it is too high, the binder in some toner parts may deteriorate, the translucent copying film may wrinkle due to heat, Since waving may occur, it is usually 60 to 200″ for thermoplastic transparent resin.
C1 preferably has a softening point or melting point of 80 to 160°C. The thickness of the thermoplastic transparent resin layer is usually 20 μm or less, preferably 10 μm or less.

After cooling, the polyethylene terephthalate film of the cover sheet was peeled off to obtain a translucent copying film in which the toner image was covered with an ethylene-vinyl acetate copolymer layer.
