上記可逆性発消色シートに関する。Detailed Description of the Invention [Industrial Application Field] The present invention relates to a sheet having a colorant layer that reversibly develops and fades color, and more particularly relates to a sheet for use in overhead projectors.
1. The present invention relates to the above-mentioned reversible color-developing and discoloring sheet using a transparent base material used for photosensitive resin masks and the like.

を考慮すると望ましい方法ではない。For the purpose of reusing such film sheets, it is possible to remove the oil-based ink forming the image using an appropriate solvent, but such a method is preferable considering the labor involved. isn't it.
［発明が解決しようとする課題］
上記のようなフィルムシートの再使用を可能にする一つ
の方法として、可逆的に発消色可能な画像を形成し用い

また、常温で発色するものは常温下では常に発色した状
態にあるため再使用は不可能であった。[Problems to be Solved by the Invention] One possible method to enable the reuse of film sheets as described above is to form and use images that can be reversibly colored and erased. For example, colorants that are conventionally known for forming a color cannot be used for OHP because those that develop color at high temperatures disappear at room temperature.
In addition, materials that develop color at room temperature cannot be reused because they remain colored at room temperature.
従って、本発明の目的は、ＯＨＰ、感光性樹脂のマスク

より達成されることを見出した。"Means for Solving the Problems" In view of the above problems, the present inventors have conducted intensive research and found that the above object of the present invention is to develop color on a transparent film base material by heating for a short time and for a long time. It has been found that this can be achieved by providing a reversible coloring/discoloring sheet provided with a colorant layer that discolors when heated.
以下に本発明を更に詳細に説明する。The present invention will be explained in more detail below.

り、可逆性着色剤層として優れたものである。The reversible colorant layer in the present invention is thermal energy (old)
For example, a colored image (including characters) is formed by heating at a high temperature, preferably 300° C. or higher, for a short time (several milliseconds to several hundred milliseconds, preferably 1 to 10 milliseconds). This image is created using another thermal energy (h2), i.e. a low temperature (humidity near or above the melting point of the developer/decolorizer, e.g. 100-200
0°C) for a long time, preferably 1 second or more, and when the thermal energy (hl) is applied again to the colorant layer from which the image has been erased, an image is formed again. Formation and erasure of this image can be repeated. This colorant layer maintains an image forming state or an image erasing state unless thermal energy is applied to it. The background after erasing the formed image is comparable to the condition of the background before image formation, and is excellent as a reversible colorant layer.
