The object of the present invention is to provide a heat-sensitive transfer image-receiving paper capable of obtaining recorded images with good color reproducibility.

明を行う。Conventional technology Conventionally, this kind of thermal transfer receiver paper and thermal melt transfer ink sheet),! :When reproducing a color image by subtractive color mixing by thermally melting transfer recording by sequentially overlapping yellow, magenta, and cyan inks, overlapping recording is required because the ink absorbency of thermal transfer receiving paper is low. It has been difficult to perform this process well, and it has been difficult to obtain recorded images with good color reproducibility. The conventional technology will be explained below with reference to the drawings.

ｂが溶融し、感熱転写受像紙３上に転写記録される。FIG. 4 shows the recording principle of this type of thermal transfer recording method. 1 is a thermal head in which heating elements R are arranged in a line in a direction perpendicular to the drawing. 2 is a heat-melting transfer ink sheet, in which a heat-melting ink 2b is applied onto a sheet film 2a. As shown in the figure, a heat-melting transfer ink sheet 2 and a heat-sensitive transfer image-receiving paper 3 are superimposed between the thermal head 1 and the platen 4, and are run in the direction of the arrow in the figure. At this time, the heat-sensitive transfer image receiving paper 3, the heat-melt transfer ink sheet 2, and the heat-melt transfer ink sheet 2
The platen 4 is pressed toward the thermal head 1 so that the heat generating element R of the thermal head 1 and the heat generating element R of the thermal head 1 are brought into sufficient contact with each other. When a voltage is sequentially applied to the heating elements H of the thermal head 1 according to the recording signal, the predetermined heating elements generate heat, and the heat-melting ink 2 on the heat-melting transfer ink sheet 2 is heated.
b is melted and transferred and recorded on the thermal transfer image receiving paper 3.

まい、記録画像の色再現性が悪くなってしまうという問
題点があった。この事についてもう少し詳しく説明する
。Problems to be Solved by the Invention The surface of conventional thermal transfer image-receiving paper is generally very smooth in order to improve image uniformity.
Therefore, thermal transfer image-receiving paper has almost no ink absorbency. Therefore, as shown in FIG. 5, the melt-transferred ink is layered on the surface to form recording dots 21. Therefore, if you try to record by overlapping two-color ink,
There has been a problem in that the adhesion between the heat-sensitive transfer image-receiving paper and the heat-melting transfer ink sheet deteriorates, making it difficult to perform recording after the two-color area, resulting in poor color reproducibility of the recorded image. Let me explain this in a little more detail.

、記録画像の色再現性の低下を招いていた。FIG. 6 is an enlarged view of the vicinity of the heating element of the thermal head during overlay recording.
is a thermal head, R is a heating element, 2 is a two-color heat-melting transfer ink sheet, 2a is a sheet film, 2b is a heat-melting ink, 3 is a conventional thermal transfer image-receiving paper, and M is melted by heating with a heating element. 21 indicates the recording dots of the first color, and 4 indicates the platen. As shown in FIG. 6, since the recording dots 21 of the negative color are layered and raised on the thermal transfer image-receiving paper 3, the adhesion between the heat-melting transfer ink sheet 2 and the thermal transfer image-receiving paper 3 is poor. , the cavity S
is created. When two-color recording is performed in this state and the heat-melt transfer ink sheet 2 is peeled off, the melted heat-melt ink M is completely transferred onto the image-receiving paper 3, as shown in FIG. First, defects occur in the recorded dots. As described above, since conventional thermal transfer image-receiving paper has almost no ink absorbency, the melt-transferred ink is not absorbed into the thermal transfer image-receiving paper 3, but instead accumulates and bulges on the surface. When performing heat-melt transfer recording by overlapping each color ink multiple times, the adhesion between the heat-melt transfer ink sheet and the thermal transfer image-receiving paper deteriorates during recording after two-color printing, making it difficult to achieve good overlay recording. This has resulted in a decrease in the color reproducibility of recorded images.

ことができるわけである。Function The thermal transfer image-receiving paper according to the present invention has a plastic deformation layer formed between the base film and the ink-receiving layer, and when performing thermal melt transfer recording by overlapping each color ink multiple times,
The plastic deformation layer plastically deforms and absorbs the swelling of the ink that has already been transferred and recorded, so the adhesion between the heat-sensitive transfer receiver paper and the heat-melting transfer ink sheet is good, and good overlay recording can be performed. This means that recorded images with good reproducibility can be obtained.
