用困難である。[Prior Art] Various thermal transfer methods are conventionally known, and among them, a sublimable dye is used as a recording agent, and this is supported on a base film such as paper or plastic film to form a thermal transfer film, and a dye-receiving method is used. Various methods have been proposed for forming a full-color image on a layered transfer material such as paper or plastic film. In this case, the thermal head of the printer is used as a heating means, and a large number of three or four color dots are transferred to the transfer material by extremely short heating, and the multicolor dots create a full-color image of the original. It is intended to reproduce. Transfer materials on which images can be formed by the above method are limited to dye-dyeable plastic sheets or paper on which a dye-receiving layer has been previously provided.
There is a problem in that an image cannot be directly formed on general plain paper. Of course, it is possible to form images on ordinary plain paper if a receptive layer is formed on its surface, but this is generally expensive, and is useful for applications such as postcards, memos, stationery, and reports. It is difficult to apply this method to general ready-made transfer materials such as paper.

熱転写フイルムも提案されている。[0003] As a method to solve such problems, when an image is to be formed on a ready-made transfer material such as plain paper, a dye-receiving layer can be easily formed only in the necessary areas. Layer transfer films are known. Furthermore, in order to improve the durability of the dye image formed as described above, a protective layer transfer film made of a transparent resin has been proposed on the dye image surface. As a way to further simplify the operation,
Each dye layer of yellow, cyan, magenta, and black if necessary is formed in sequence on the surface of a long base film,
Furthermore, a transferable dye-receiving layer and/or a transferable protective layer are provided on the same base film surface, and the receiving layer is first transferred to a transfer material, and then the dyes of each color are transferred to the receiving layer to form a full-color image. Composite thermal transfer films have also been proposed in which a protective layer is transferred onto the image surface.

成される画像形成方法を提供することである。[Problems to be Solved by the Invention] In the above method, when the dye-receiving layer is transferred in a pattern using a thermal head, if the material to be transferred is paper that lacks surface smoothness such as plain paper or postcards, A problem arises in the adhesion between the transfer layer and the transfer receiving layer, resulting in a problem that a uniform receiving layer is not transferred. This problem can be solved by increasing the thermal energy applied to the transfer film, but if the transfer of the receptive layer is continued in such a high thermal energy state, the surface of the transferred receptive layer will deteriorate as a result of heat accumulation inside the printer. Problems such as matting (unevenness) or fusion of the receiving layer transfer sheet and the thermal head may occur, such as hindering the running performance of the transfer film or tearing the transfer film. Furthermore, if a release layer is formed between the receptor layer of the transfer film and the base film, this release layer will melt, resulting in poor peeling of the receptor layer and insufficient transfer of the receptor layer. This problem arises. If the thermal energy applied is set low from the beginning in consideration of heat accumulation in the printer as described above, transfer defects will occur in the initial state of transfer.
There are problems in that a receiving layer is transferred that has many omissions and chips and has irregular edges. The above-mentioned problems also occur when a protective layer is transferred from a protective layer thermal transfer sheet to the image surface formed on the receiving layer. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an image forming method in which a dye-receiving layer and/or a protective layer are uniformly transferred, and an excellent sublimation dye image is formed as a result. be.

あってもよいのは当然である。Preferred Embodiments The image forming method of the present invention will be explained in more detail with reference to preferred embodiments shown in the drawings. To explain some preferred examples of the present invention, as schematically shown in FIGS. 1a to 1e, when a dye receiving layer is transferred from a dye receiving layer transfer film to a desired area of a transfer material using a thermal head, (1) A method in which the thermal energy supplied from the thermal head is at a sufficient level at the start of transfer, and the thermal energy supplied to the thermal head is gradually reduced in response to heat accumulation within the printer (Figure 1a). (2) Similar to 1 above, some time (
(i.e. the time it takes for the printer to warm up) by supplying sufficient thermal energy from the thermal head and then reducing the supplied thermal energy level (Figure 1b). (3) When transferring the receptor layer, the material to be transferred and the receptor layer transfer sheet are conveyed at a speed corresponding to the rotational speed of the platen, but in this case, the conveyance speed of the material to be transferred and the transfer film is gradually reduced. Up it. At this time, the thermal energy supplied from the thermal head is constant (FIG. 1c). (4) Same as (3) above, but the supply heat energy is kept constant, and at the start of transfer, the conveyance speed of the transfer material and transfer film is set to 0 or low, so that the printer warms up. After that, the conveyance speed is set to a predetermined speed. In this case, since heat accumulation within the printer is taken into account, the thermal energy supplied from the thermal head may be at a somewhat lower level (FIG. 1d). (5) At the start of receptor layer transfer, the contact pressure (linear pressure) of the thermal head against the transfer film is kept high for a while (until the printer accumulates heat), and after the printer accumulates heat, the linear pressure is kept low. (Fig. 1e). FIG. 2 is a diagram illustrating the state of supply of thermal energy in the prior art, and various problems described in the above-mentioned "Problems to be Solved by the Invention" section occur. The above is a case of transferring a receptor layer, but the same applies to transferring a protective layer. Further, in the present invention, the amount of thermal energy applied to the dye-receiving layer (or protective layer) transfer film by the thermal head is initially high and is applied thereafter as long as it substantially decreases over time. Naturally, there may be quantitative fluctuations in thermal energy.

A highly transparent and durable protective layer 52 made of acrylic resin, vinyl chloride-vinyl acetate copolymer, etc. is formed, and if necessary, a protective layer 52 of vinyl chloride-vinyl acetate copolymer, acrylic resin, polyamide, etc. is formed thereon. An adhesive layer 53 made of adhesive is formed, and a heat-resistant slipping layer 54 is formed on the opposite side as required. As shown in FIG. 6, this is superimposed on the surface of the image 63 formed on the transfer material 61, and by the method of the present invention, the protective layer 64 can be transferred only to the required area of the image from the back side using a thermal head. The durability of the image can be further improved by transferring such a protective layer slightly larger than the image surface as shown in FIG. Such a protective layer transfer film itself is described in detail in the applicant's prior application specification. Further, instead of the above-mentioned protective layer, a protective laminate sheet such as a polyester film or a vinyl chloride resin film may be attached to the image surface via a hot roll or hot press, if necessary, via an adhesive layer. In this case, the above-mentioned protective layer and laminate sheet may have an ultraviolet blocking effect. Furthermore, in the present invention, as schematically shown in FIG.
Images are transferred as described above using a composite transfer film in which at least two layers among the dye-receiving layer 72, the dye layers Y, M, and C of each color, and the protective layer 73 are sequentially provided on the surface of the base film 71.
