Field of the Invention The present invention relates to heat-sensitive transfer recording, and particularly to an image-receiving paper which is remarkably improved in image quality when applied to a fusion-type color thermal transfer printer having a line-type recording head having a resolution of 300 DPI or more. is there.

後で述べる理由により実用化されていなかった。The thermal transfer recording technology is roughly classified into a dye diffusion type and an ink melting type. Although the dye diffusion type is suitable for high-quality pictorial art, it has drawbacks such as long recording time and high running cost due to the use of a special image receiving paper. On the other hand, the ink fusion type is mainly used for documentary color applications such as characters and figures, but it has not been put to practical use for high image quality pictorial art applications for the reason described later.

されている。The basis of the ink-melting type thermal transfer technology is to superimpose a heat-melting ink sheet and an image-receiving paper and heat a thermal head to thermally convert an image signal to transfer the heat-melting ink to the image-receiving paper. Consists of. In color recording,
Cyan, magenta, yellow, and black inks are sequentially transferred, and the individual inks are superposed or transferred in the vicinity to form a color image. Furthermore, when performing full-color recording, halftone reproducibility is important for producing gradation, and as an example of this technical means,
For example, an area gradation method for controlling the size of transfer dots, a density gradation method for controlling the transfer amount of heat-meltable ink, and the like have been reported.

ある。However, the reason why the ink-melting type thermal transfer system has not been put to practical use for a high-quality full-color image is that an image-receiving paper having sufficient transferability has not been developed. When an image receiving paper with paper as a base material is used, the smoothness of the paper causes a problem that the ink adheres only to the convex parts of the paper and the concave parts become blank, resulting in uneven dot shapes and gradation. This is because the quality of the full-color image that it has is inferior.

No. -144699 specifies smoothness of 5000 seconds or longer, and smoothness is improved by super calendering. However, the super calender treatment is not preferable because the density of the paper is increased and the cushioning property, which is another means for increasing the contact area with the thermal head, is impaired. From this viewpoint, Japanese Patent Laid-Open No. 1-30
No. 1283 proposes to provide a layer having cushioning properties as an intermediate layer. However, in this method, since the cushioning property is expressed only by the coating layer, it is not sufficient as the cushioning property to make the dot shape of the full-color image uniform, and the cost increase due to multiple coating steps. Therefore, it is not preferable.

The purpose is to do.

An ink receiving layer is provided on cast-coated paper having a speed of 1,000 seconds or more, and a solvent-soluble resin and an average particle size are included in the ink receiving layer.
By using a pigment of 0 μ or less, a thermal transfer image-receiving paper having suitability for a full-color image was invented.

立させる必要がある。The background to the invention of the present application was to improve the reproducibility of the dot shape in the highlight portion. In order to increase the ink transfer rate to the image receiving paper, it is necessary to increase the contact area between the thermal head and the image receiving paper via the ink sheet. This measure has conventionally been dealt with by increasing the smoothness of the image receiving paper, but with the transition from monochrome images to color images and further to full-color images, it is no longer possible to deal only with increasing smoothness. . As a full-color image receiving paper, it is necessary to have both smoothness and cushioning properties.

ルムは最上位の平面性を有するが、高価である。As a base material for image receiving paper, high-quality paper, coated paper, art paper, synthetic paper, polyester film and the like have been conventionally used. Fine paper lacks smoothness on the image receiving surface, and coated paper and art paper have good smoothness but lack cushioning properties. Synthetic paper is good because it has both smoothness and cushioning properties, but it cannot be used as a base material for image-receiving paper because it lacks thermal dimensional stability. Moreover, polyester films have the highest level of planarity, but are expensive.

のである。The present invention achieves its object by using cast coated paper as a coating substrate. The cast coated paper has a smooth surface by copying the mirror surface of the cast drum surface in parallel with the drying of the coating layer.
Therefore, super calendar processing is unnecessary. Furthermore, by changing the density of the coated base paper for cast coat,
The density or cushioning property of the final image receiving paper can be freely controlled.

きたす場合が生ずる。Further, the density of the cast coated paper used in the present application is in the range of 0.8 to 1.0 g / cm 3 , and 1.0 g
If the density is higher than / cm 3 , the cushioning property will be insufficient. The smoothness must be 1000 seconds or more. Since the coating thickness of the ink receiving layer is very thin, the smoothness of the coating substrate directly affects the smoothness of the image receiving paper. The weight of cast coated paper is 5
It can be used in the range of 0 to 200 g / m 2 , preferably 80
Is about 120 g / m 2 . From the perspective of cushioning,
The larger the basis weight, the larger the amount of displacement at the time of compression, which is advantageous. However, if the paper thickness is too large, the paper passing property of the printer may be impaired.

る事はできない。An ink receiving layer is applied to the coated surface of the cast coated paper. The coating liquid in the present application is limited to the solvent-based coating liquid. In the water-based coating liquid, the cellulose fiber, which is a constituent unit of the paper, swells with water as the solvent, or the cast coat layer loses the mirror-finished state that was copied due to rewetting, and further dry wrinkles occur in the drying process, and the flatness deteriorates. To do. If super calendering is applied as a countermeasure against this, it is not possible to achieve both flatness and cushioning, which is the object of the present application.

果たしており、特にこの層を設ける必要はない。One of the features of the present application is that the solvent-based coating liquid is used and super calendering is not required. Generally, when a solvent-based coating liquid is applied to a paper substrate having a low density, the solvent penetrates into the paper, resulting in insufficient formation of a coating film. Therefore, a barrier layer is generally provided, but in the present application, the cast coat layer also functions as a barrier layer, and it is not particularly necessary to provide this layer.

As the solvent-soluble resin, known resins such as polyethylene, polypropylene, polyvinyl chloride, polyvinyl acetate, polystyrene, polyvinyl butyral, polyacrylic acid ester, polymethacrylic acid ester, polyester, etc., such as homopolymer or copolymer resin are used. it can. Furthermore, it is also possible to mix and use these resins. The resin that can be used in the present invention is selected as a resin having a relatively low softening point based on the adhesiveness to ink as an index. Specifically, it is selected and determined according to the type and compatibility of the ink layer binder.

る。Further, the ink receiving layer has an average particle size of 2.0 μm.
The following pigments are added. The purpose of the pigment addition in the present application is to prevent blocking. With a pigment having an average particle size of more than 2.0 μm, the pigment particle size is too large and the flatness is reduced, resulting in white spots in the image. By using a pigment having an average particle size of 2.0 μ or less, blocking can be prevented without lowering the smoothness. The pigment blending ratio does not aim at ink absorbency, so that the purpose can be achieved at 5.0% or less.
