Further, when a metal ion-containing compound is blended in the image receiving layer, a sublimable dye that reacts with the metal ion-containing compound to form a chelate may be included in the sublimable dye-containing ink layer. Examples of such chelate-forming sublimable dyes are described in JP-A Nos. 59-78893, 59-109349, 4-094974, 4-0978894, and 4-089292.

As for any sublimation dye, the sublimation dye contained in the sublimation dye-containing ink layer may be any of a yellow dye, a magenta dye, and a cyan dye as long as the image to be formed is a single color. In addition, depending on the color tone of the image to be formed, any two or more of the three kinds of dyes or other sublimable dyes may be included. The amount of the sublimable dye used is usually 0.1 to ²⁰ g, preferably 0.2 to 5 g, per 1 m ^{2 of} the support. Further, the ink sheet support may have an undercoat layer for the purpose of improving adhesiveness with the binder and preventing the transfer and dyeing of the dye to the ink sheet support. Further, the back surface of the ink sheet support (opposite to the ink layer) is stuck for the purpose of preventing fusing and sticking of the head to the ink sheet support and wrinkling of the heat sublimation thermal transfer ink sheet. A prevention layer may be provided. The thickness of the overcoat layer, undercoat layer and anti-sticking layer is usually 0.1 to 1 μm.

[Hot Melting Image Forming Method]
<Hot-melting ink layer>
The ink sheet for hot melt transfer recording can be composed of a support and a hot melt-containing ink layer formed thereon. The heat-meltable ink layer is composed of a heat-meltable compound, a thermoplastic resin, a colorant, and the like. Further, like the sublimation type thermal transfer recording ink sheet, an anti-sticking layer may be provided for the purpose of preventing wrinkling of the hot melt type thermal transfer ink sheet. The thicknesses of the overcoat layer, the undercoat layer, and the anti-sticking layer are usually 0.1 to 1 μm.

  As the heat-meltable compound, those usually used for the heat-meltable ink layer of this kind of heat-melt type thermal transfer recording ink sheet can be arbitrarily used. Specifically, for example, polystyrene resin Low molecular weight thermoplastic resins such as acrylic resin, styrene-acrylic resin, polyester resin, polyurethane resin, etc., from page 4, upper left column, line 8 to upper right column, line 12 of JP-A-63-193886. In addition to these, rosin, hydrogenated rosin, polymerized rosin, rosin modified glycerin, rosin modified maleic resin, rosin modified polyester resin, rosin modified phenolic resin, ester gum, etc. Rosin derivatives, phenolic resins, terpene resins, ketone resins, cyclopentadiene resins and aromatic hydrocarbons , And the like fat. These heat-meltable compounds preferably have a molecular weight of usually 10,000 or less, particularly 5,000 or less, and a melting point or softening point in the range of 50 to 150 ° C. The said heat-meltable compound may be used individually by 1 type, and may be used in combination of 2 or more type. As the thermoplastic resin used as a component of the heat-meltable ink layer, various materials such as those usually used for the heat-meltable ink layer of this kind of heat-melt type thermal transfer recording ink sheet can be used. For example, the substances exemplified in JP-A 63-193886, page 4, upper right column, line 16 to page 5, upper left column, line 18 can be mentioned. As the colorant used as a component of the heat-meltable ink layer, those usually used for the heat-meltable ink layer of this kind of heat-melt type thermal transfer recording ink sheet can be used without limitation. Examples thereof include inorganic pigments, organic pigments and the like, and dyes such as organic dyes described in JP-A 63-193886, page 5, right upper column, lines 3 to 15.

  These various colorants may be used alone or in combination of two or more as required. In the heat-meltable ink layer, other additive components other than those described above can be appropriately added as necessary within the range not impairing the object of the present invention. For example, this hot-melt ink layer may contain a fluorinated surfactant. By containing the fluorosurfactant, the blocking phenomenon of the hot-melt ink layer can be prevented. It is also effective to add organic fine particles, inorganic fine particles, and incompatible resins in order to improve the sharpness of the transferred character information-containing image, that is, the character boundary portion. The film thickness of the hot-melt ink layer is usually 0.6 to 5.0 μm, and preferably 1.0 to 4.0 μm. This heat-meltable ink layer is formed by dispersing or dissolving the forming components in an organic solvent (organic solvent method), or by applying a thermoplastic resin in a softened or molten state by heating (hot-melt coating method). However, it is preferably coated using an emulsion or solution in which the forming component is dispersed or dissolved in water or an organic solvent. The total content of the layer forming components in the coating liquid used for coating the heat-meltable ink layer is usually set in the range of 5 to 50% by weight. The coating method can be performed using a normal method. Examples of the coating method include a method using a wire bar, a squeeze coating method, and a gravure coating method. In addition, the heat-meltable ink layer needs to be provided in at least one layer. For example, the two layers differ in the type and content of the colorant or the blending ratio of the thermoplastic resin and the heat-meltable compound. The above heat-meltable ink layer may be laminated.

[Formation of authentication identification image]
In order to form an authentication identification image, the heat diffusible dye-containing ink layer of the sublimation type thermal transfer recording ink sheet and the image receiving layer on the substrate are overlapped, and the heat diffusible dye containing ink layer and the image receiving layer are imagewise. Heat energy. Then, the heat diffusible dye in the heat diffusible dye-containing ink layer is vaporized or sublimated by an amount corresponding to the heat energy applied at the time of image formation, and transferred to the image receiving layer side. A gradation information-containing image is formed.

  A thermal head is generally used as a heat source for applying thermal energy, but other known devices such as laser light, infrared flash, and thermal pen can be used. When a thermal head is used as a heat source for applying thermal energy, the applied thermal energy can be changed continuously or in multiple stages by modulating the voltage or pulse width applied to the thermal head. When laser light is used as a heat source for applying thermal energy, the thermal energy to be applied can be changed by changing the amount of light and the irradiation area of the laser light.

  In this case, in order to easily absorb the laser light, a laser light absorbing material (for example, in the case of a semiconductor laser, carbon black, a near-infrared absorbing substance, etc.) is preferably present in the ink layer or in the vicinity of the ink layer. When using laser light, the sublimation type thermal transfer recording ink sheet and the image receiving layer on the substrate are preferably adhered sufficiently.

  If a dot generator incorporating an acousto-optic device is used, thermal energy can be given according to the size of the halftone dots. When an infrared flash lamp is used as a heat source for applying thermal energy, heating is preferably performed through a colored layer such as black as in the case of using laser light. Alternatively, heating may be performed through a pattern or halftone dot pattern that continuously represents the shade of the image, such as black, or a negative pattern corresponding to a colored layer such as black on one side and the negative of the above pattern. Heating may be performed in combination.

  The heat energy may be applied from the sublimation type thermal transfer recording ink sheet side, from the thermal transfer recording image receiving sheet side, or from both sides, but priority is given to effective use of thermal energy. Then, it is desirable to perform from the ink sheet side for sublimation type thermal transfer recording. With the thermal transfer recording described above, a single color image can be recorded on the image receiving layer of the thermal transfer recording image receiving sheet. However, according to the following method, a color photographic tone color image composed of a combination of the respective colors can be obtained. For example, by sequentially replacing yellow, magenta, cyan and, if necessary, black thermal transfer recording thermal sheet and performing thermal transfer according to each color, it is also possible to obtain a color image of a color photographic tone consisting of a mixture of the respective colors. .

  Then the following method is also effective. That is, instead of using the sublimation type thermal transfer recording ink sheet of each color as described above, a sublimation type thermal transfer recording ink sheet having areas previously formed separately for each color is used. Then, the yellow color separation image is first thermally transferred using the yellow area, and then the magenta color separation image is thermally transferred using the magenta area, and thereafter, yellow, magenta, cyan, and necessary are sequentially repeated. Thus, a method of performing thermal transfer in order with a black color separation image is adopted.

  Further, after the image is formed by the above method, the heat treatment may be performed by the method described above for the purpose of improving the image storage stability. For example, the entire surface of the image forming surface is heated using a portion of the ink sheet for sublimation type thermal transfer recording that is not provided with the heat diffusible dye-containing ink layer with a thermal head, or a new heating process such as a heat roll. May be performed. Further, when a near-infrared absorber is contained, the image forming surface may be exposed using an infrared flash lamp. In any case, any heating means may be used. However, since the purpose is to further diffuse the dye inside the image receiving layer, it is effective to heat the heating direction from the support side of the image receiving layer. Is preferably used.

In the present invention, the image-receiving layer of the thermal transfer recording image-receiving sheet and the hot-melt type thermal transfer recording sheet are overlapped to form 0.3 kg / cm ^{2 to} 0 according to the recording signal when an image is formed. It is preferable to form an image containing gradation information at a pressure of 0.01 and a head temperature of 50 to 500 ° C., preferably 100 to 500 ° C. and 100 to 400 ° C. More preferably, it is 0.25 kg / cm < ² > -0.01, More preferably, it is 0.25 kg / cm < ² > -0.02.

[Formation of attribute information image]
The hot-melt transfer method using the hot-melt heat-sensitive transfer recording ink sheet is not different from the normal heat-transfer transfer recording method, but the case where the most typical thermal head is used as a heat source will be described as an example. . First, the heat-meltable ink layer of the heat-melt type thermal transfer recording ink sheet and the image-receiving layer surface of the base material are brought into close contact with each other. Alternatively, the hot-melt ink layer corresponding to the transfer pattern is locally heated.

  The temperature of the heated portion of the heat-meltable ink layer rises, quickly softens, and is transferred to the image receiving surface of the substrate. The formation of the non-gradation information-containing image that does not require gradation such as characters, figures, symbols, or ruled lines may be performed prior to the formation of the gradation information-containing image. The non-gradation information-containing image may be formed after the tone information-containing image is formed. The character information-containing image can also be formed by using the sublimation type thermal transfer recording ink sheet.

In this invention, the image-receiving layer of the thermal transfer recording image-receiving sheet and the heat-melt type thermal transfer recording sheet are overlapped to form 0.3 kg / cm ² according to the recording signal when forming a character information image. It is preferable to form a gradation information-containing image at a pressure in the range of -0.01 and a head temperature of 50-500 ° C, preferably 100-500 ° C, 100-400 ° C. More preferably, it is 0.25 kg / cm < ² > -0.01, More preferably, it is 0.25 kg / cm < ² > -0.02.

[Inkjet]
In the case of adopting the ink jet method, for example, a resolution of about 400 dpi is sufficient for the bubble jet (registered trademark) method, and a multi-gradation can be achieved for the face image by the shear mode method.

Or inks described in JP-A-9-71743, JP-A-2000-297237, JP-A-2000-85236, JP-A-5-1254, and the like. Further, post-heating, post-exposure, and the like may be performed after character information, a face image, and the like are written by inkjet as post-processing, and the ink type and image forming method are not particularly limited.
