Among these, the thermal transfer method is often used because it is noiseless and easy to maintain. This thermal transfer consists of a solidified color ink sheet and image receiving paper, and the ink is thermally melted transferred or sublimated onto the image receiving paper using thermal energy controlled by electrical signals from a laser or a thermal head to form an image. This is a recording method.

た方式と考えられている。This thermal transfer method includes a heat melt transfer type and a sublimation transfer type. The heat-melting transfer type uses an ink sheet in which pigments or dyes are bonded with hot-melting wax, and the pigments or dyes are transferred to image-receiving paper along with the wax melted by the thermal energy of the thermal head.For this reason, it is necessary for M quality. The drawbacks are that it is difficult to obtain a good midtone, and because of the transferred wax, it is difficult to obtain a good hue. On the other hand, the sublimation transfer type using sublimation dyes is an application of conventional sublimation transfer printing technology, and uses a sheet in which -fi is bound with a binder to a disperse dye that is relatively easy to sublimate. The energy sublimates and transfers the dye to the receiving paper to form an image. At this time, the sublimation dye sublimates in response to the heat energy of the thermal heater, so it is easy to obtain intermediate tones and has the advantage of being able to control the gradation to a full color printer. It is considered to be the most common method.

Although it is possible to use various types of plastic films, it is not possible to obtain sufficient color density with plastic film alone, and the color fading over time is significant due to the poor fixability of sublimable dyes. That's why I don't like it. For this reason, a dyeing resin layer made of a thermoplastic resin that can be effectively dyed with sublimable dyes, such as saturated polyester resin, polyamide resin, and epoxy resin, is generally provided on a plastic film. However, when heating a print, the temperature of the thermal head is generally 30°C.
Since the temperature reaches 0'C, both the binder of the thermal transfer paper and the dyeing resin of the OHP film are softened by the heat, and both fuse, making it impossible to run or causing abnormal transfer of the ink layer. The problem was P). Therefore, in order to prevent this fusion, a part of the dyeing resin is cured with an appropriate hardening agent, or a resin with strong peeling properties and high heat resistance such as silicone resin or melamine resin is dyed. ? Countermeasures have been taken, such as providing on the resin.

充分に認知し難くなるおそれがあった。However, since the OHP film obtained in this way is almost colorless and transparent, it is difficult to optically distinguish it from the color of the lining.
There was a problem in that it was difficult to locate the beginning accurately, and positional deviation occurred when printing the three colors of cyan, magenta, and yellow sequentially. In addition, it is difficult to distinguish between the front and back sides of these OHP films, so there is a risk that they will be inserted into the printer with the front and back sides reversed. There was a risk that the thermal transfer paper and the OHP film would fuse together, making it impossible to run, causing printer failure, or that the thermal transfer paper would break and become unusable. Furthermore, if optically detectable detection markers are provided on OHP films, the light will be blocked and shadows will appear when images are taken with an overhead projector, and when viewed overlaid on printed matter, the printed matter may not be fully visible. There was a risk that it would be difficult to recognize.

The goal is to solve each of the key points of P film, and more specifically, there is no misalignment when printing the three colors of cyan, magenta, and yellow side-by-side, and there is no trouble due to fusion even if the film is set upside down. It is an object of the present invention to provide an OHP film in which light does not occur and in which light is not blocked when actually projected using an overhead projector.

This optical detection marker made of a removable adhesive sheet is one in which an optically detectable detection marker is printed using a printer and then can be easily peeled off and removed by hand. In fact, when taking pictures using an overhead projector, the light is blocked by the detection marker to prevent shadows from appearing. A detection marker made of such a releasable adhesive sheet has a pressure-sensitive adhesive (1) on either side of the detection marker sheet (2) as shown in Figures 1 and 2.
It can be obtained by applying it partially or completely.

識別が出来るような機能をもたせることも出来る。In this way, OHP films provided with optical detection markers made of removable adhesive sheets can be used to detect optical reading devices such as transmissive and reflective types, as well as their optical density, hue, polarization, etc. The position of the detection marker can be accurately read by detecting it as an OFF signal. By storing information regarding the start of the thermal head in this detection marker, a good image without positional deviation can be obtained when printing the three colors of cyan, magenta, and yellow sequentially. An OHP film equipped with such a detection marker has the above-mentioned functions and can visually and tactually distinguish between the front and the back depending on the presence or absence of the detection marker. It is also possible to provide a function that allows identification.

することを光学的に確実に排除出来る。The detection marker that can distinguish between the front and the back may have any shape as long as it can distinguish between the front and the back, and various shapes can be widely employed. The typical forms are as follows. For example, in a configuration in which detection markers are provided in a non-linearly symmetrical manner so that the position of the detection marker is different depending on the front and back sides, and in order to make it possible to identify the front and back sides of the detection marker sheet (2), a composition containing a coloring agent is used. Forms in which objects are coated on colored plastic films or paper, or two or more compositions consisting of different colorants are coated on both or one side of the film so that the front and back sides have different optical densities, hues, etc. In addition, examples include using two or more types of adhesive sheets with different optical densities and hues to provide multiple layers on one side of an OHP film, or providing separate layers on both sides of the OHP film. In this way, OHP film, which has different detection markers depending on the front and back sides, can be set with the front and back sides reversed by feeding the paper feed mechanism with the difference in information obtained from the optical reader installed at a specific position in the printer. This can be optically and reliably eliminated.

ように額取り部あるいは全面に設けることが望ましい。The examples shown in FIGS. 3 to 7 are examples of the present invention, and the present invention is not limited thereto. The detection marker (4) is made of dyed resin to which the sublimable dye is transferred. They may be provided anywhere other than on the layer, and two or more may be provided on the same surface or on both sides! 11 The detection marker (4) is placed on the framed portion of the surface where the dyed resin layer on which the image is formed is not subjected to the transfer of the sublimable dye.
Alternatively, it is sufficient to provide the detection marker (4) in at least one place on the back surface where the image is not formed. However, when providing the detection marker (4) on the back surface where the image is not formed, it may be provided in any location, but the part where the image is formed. It is desirable to provide the frame on the frame or the entire surface so that there are no steps.
