Demand is increasing year by year. Additionally, demand for color facsimiles is increasing. Recording methods for such color printers and color facsimiles include an electrophotographic method, an inkjet method, a thermal transfer method, and the like. Among these, the thermal transfer method is widely used because it is noiseless and the apparatus is easy to maintain. This thermal transfer method consists of a combination of a color ink sheet containing a dye and an image receiving paper. Images are formed by thermally melting and transferring ink from a color ink sheet to a thermal transfer image receiving paper using thermal energy controlled by electrical signals from a laser or thermal head, or
Or by sublimation transfer.

Apply it in a shape,
It has been disclosed that multicolor recording is performed by selectively heating ink spots of desired colors during recording. The first method disclosed herein is a transfer type (or printing), in which a recording sheet is brought into close contact with a heat-sensitive ink paper coated with hot-melt solid ink of two or more colors in dots as described above. Ink spots of a desired color on ink paper are selectively heated and melted to perform transfer recording onto recording paper. The second method is a direct coloring type, in which heat-sensitive colorable solid ink of two or more colors is applied in advance to the recording paper in dots as described above, and the ink dots of the desired color are selectively heated and colored. This is to record the information.

い。However, even if such a method is used, there are some problems. For example, in the first method, thermal ink paper is required in addition to recording paper, and the structure of the device is also complicated, making it difficult to incorporate it into a small device such as a magnetic camera and perform image formation. Furthermore, since the second method uses a heat-sensitive color-forming solid ink, the storage stability of the print is not sufficient.

Then, either a concealing layer is provided on top of this so that only the necessary dye parts appear during recording, or an array of dyes is provided on a white sheet medium so that only the necessary dye parts remain during recording.

保存安定性に優れる。Further, a regular and dense arrangement in the plane direction means, for example, a coloring material layer consisting of a dot-shaped dye arrangement with a diameter of 1 mm or less as shown in FIG. 2, or a striped pattern with a line width of 1 mm or less as shown in FIG. Examples include a coloring material layer made of a pigment in the form of a pigment, a coloring material layer made of a honeycomb-shaped pigment as shown in FIG. If the diameter of the dots or the line width of the stripes exceeds 1 mm, the resulting image will become rough. As shown in Figures 2 and 3, in the case of dotted dye arrays, it is necessary to control both the sheet running direction and the discharge or laser beam scanning line direction for positioning, but in the case of striped dye arrays, only the sheet running direction is required. This is preferable because it is easy to control during printing. The white layer can be coated by gravure coating or melt extrusion of a mixture of fine white powder such as titanium white or talc and a binder resin (for example, polyester resin, butyral resin, epoxy resin, phenoxy resin, acrylic resin, etc.) However, it is not limited to these. In addition, the thickness of the white layer is preferably as thin as possible as long as the color of the underlying layer is hidden.
Generally, 1 to 5 μm is preferable. In order to perform recording using such recording paper, as shown in FIG. 1(b), only the white layer above the necessary dye area is removed to form the colored area 4, and the other areas are left as the white area 5. Multi-color recording is performed by leaving the image. As a method for removing the white layer, laser beam irradiation, removal by discharge, infrared rays, ultraviolet rays, or other suitable heat rays or light rays may be used. The color density of each dye in a color image obtained using such a recording medium is constant, the resulting color image is close to a multicolor image, and the image has excellent storage stability.

By providing the black layer above or below the white layer or below the dye layer and controlling the thickness of the layer to be removed, it becomes easier to reproduce a black color with high density. That is, as shown in FIG. 5(a), a black layer 6 is provided above the color material layer 2 and the white layer 3, and if white is required, only the black layer 6 is removed to provide a white portion 5, and various If color is required, multicolor recording may be performed by removing up to the white layer 3 to provide a coloring section 4. Further, as shown in FIG. 5(b), a black layer 6 is provided between the white layer 3 and the color material layer 2 of the recording medium, and if black is required, only the white layer 3 is removed, and if various colors are required, the black layer 6 is removed. For example, multicolor recording may be performed by removing up to the black layer 6. Furthermore, as shown in FIG. 5(c), a black layer 6 is provided below the coloring material layer 2, and if black is required, up to the coloring material layer 2 is removed, and if various colors are required, only the white layer 3 is removed. Multicolor recording may be performed by doing so. The thickness of the coloring material layer in these cases is 0
．． The thickness is preferably about 1 to 0.5 μm. In particular, it is preferable that the layer to be removed has the minimum thickness that can hide the black color or each color of the underlying layer.

In such a recording medium, as shown in FIG. 6(b), only the resin layer 7 on the necessary dye part is heated by applying the required energy in the same manner as described above to form a transparent part 8, and the other parts are left with a cloudy part 9. shall be.
