2. Description of the Related Art Conventionally, as a recording method by a thermal transfer method, a sublimation dye is applied to a base film of paper or a plastic sheet to form a sublimation type thermal transfer film, and a paper or a plastic as a transfer material provided with a dye receiving layer. There is a technique for forming a full-color image on a sheet. The image formed in this way is very clear because the coloring material used is a dye, and because the transparency is excellent, the resulting image has excellent reproducibility of intermediate colors and gradation, It is possible to form high-quality full-color images comparable to printing and gravure printing. However, there is a problem that it cannot be said to be sufficient for image formation that requires a sharp density such as a barcode.
Further, the image-receiving sheet capable of forming an image by the above method is limited to a transfer material such as a dye-adhesive plastic sheet or a paper on which a dye-receiving layer is provided in advance.
There is a problem that an image cannot be directly formed on coated paper or the like, and it cannot be applied to ready-made recording paper such as postcards, letter paper, and report paper.

When an image is to be formed by sublimation transfer printing on a ready-made paper such as plain paper, a receptive layer transfer sheet is known for providing a dye receptive layer only on a necessary portion thereof. (For example, JP-A-62-26499
4 publication). However, when sublimation transfer printing is performed,
There is a problem that it cannot be said to be sufficient for image formation that requires sharpness and density such as barcodes. In addition, since the image of the dye transfer is formed on the surface, it has poor durability, is particularly weak in abrasion resistance, and is easily attacked by a low molecular weight organic substance such as a plasticizer in a plastic case.

In the present invention, a particularly preferable resin is a polyvinyl chloride / vinyl acetate copolymer having a degree of polymerization of 350 or less. When the degree of polymerization exceeds 350, the film strength of the receiving layer is too strong, so that accurate transfer cannot be performed when a fine patterned receiving layer is transferred, and the edge of the transfer receiving layer is poorly cut, which may result in poor transfer. . Particularly preferred degree of polymerization is 150 to
When the degree of polymerization is 350 and the degree of polymerization is less than 150, the film strength after transfer is insufficient, and when the dye is transferred, it adheres to the hot-melt ink or dye layer of the sublimation type thermal transfer film or the hot-melt type transfer film, and the receiving layer. May be taken. It is preferable to mix a release agent with the above-mentioned resin, and silicone oil, phosphoric acid ester-based surfactant, fluorine-based surfactant and the like can be mentioned. Silicone oil is preferable. Epoxy-modified, amino-modified, carboxyl-modified, alcohol-modified, fluorine-modified, epoxy-polyether-modified silicone oils are used. The amount of these releasing agents added is preferably 0.2 to 2.0 parts by weight with respect to 100 parts by weight of the resin for forming the receiving layer. If the addition amount range is not satisfied,
Problems such as fusion of the thermal transfer film and the receiving layer or reduction of printing sensitivity may occur. Further, if the addition amount exceeds the above range, the image of the printed matter may have poor adhesion to the transfer material.

EXAMPLES Next, the present invention will be described more specifically with reference to examples. (Example 1) A transparent resin layer coating solution having the following composition was applied on one side of a 50 μm white polyester film (Toray: Lumirror) by a 2 μm bar coat, and then a receiving layer coating solution having the following composition was applied on the top surface thereof. A 4 μm bar coat was applied and dried to form a transfer type image receiving paper used in the present invention. Printed on the other side of a 6 μm-thick polyester film (Toray: Lumirror) with a heat-resistant back layer, using a hot-melt ink containing carbon of the following composition and an ink containing sublimation dyes of red, yellow and indigo. A sublimation type thermal transfer film was prepared. -Transparent resin layer coating liquid Acrylic resin BR-55 (Mitsubishi Rayon) 20 parts MEK 40 parts Toluene 40 parts-Receptor layer coating liquid Vinyl chloride / vinyl acetate copolymer 1000A (electrochemical) 20 parts Modified silicone KF393 (Shin-Etsu) Chemical) 0.2 parts Modified Silicone X-22-343 (Shin-Etsu Chemical) 0.2 parts-Hot melt ink (ink for hot melt transfer film) Acrylic resin BR83 (Mitsubishi Rayon) 20 parts Carbon black 5 parts MEK 35 parts Toluene 40 parts- Ink containing sublimation dye (ink for sublimation type thermal transfer film) Dye (Example: Solvent Blue) 5.5 parts Polyvinyl butyral resin (Sekisui Chemical Co., Ltd.) 3.0 parts MEK 22.5 parts Toluene 70.0 parts The transfer type image receiving paper And the thermal transfer film, the receiving layer, the dye layer and the hot-melt ink layer facing each other. And then record from the back of the thermal transfer film using a printer equipped with a thermal head, and form a full-color image with a sublimation dye and an image with a line drawing with hot-melt ink on the receiving layer of the transfer type image receiving paper. The thermal transfer print of the invention was prepared. Next, plain paper as a material to be transferred is overlaid on the printed matter and heated with a thermal head from the back side of the transfer type image receiving paper, the printed matter is transferred together with the transparent resin layer and the receiving layer, and a full-color image by a sublimation dye and a hot-melt ink. An image having a line drawing according to the above was formed on plain paper.

INDUSTRIAL APPLICABILITY According to the present invention, a sublimation dye receiving layer is formed on a transfer type image receiving paper to form a thermal transfer sheet having a multicolor image by sublimation transfer, which has high image quality, and a high-concentration printed matter by hot-melt ink. We were able to. Further, since the image is provided between the transparent resin layer serving as the protective layer and the paper or film, the abrasion resistance and durability of the image are improved, and a smooth image can be obtained even on a rough paper surface with unevenness. It is possible to form an image that is not easily attacked by a low molecular weight organic material such as a plasticizer of a plastic case.
