The image-receiving layer according to the present invention is a heat-sensitive transfer recording image-receiving layer in which a heat diffusible dye receiving layer is laminated, and forms a gradation information-containing image by a sublimation type thermal transfer system.
Since the character information-containing image is formed by the sublimation type thermal transfer system or the fusion type thermal transfer system, the dyeability of the sublimable dye, or the dyeability of the sublimable dye, and the adhesiveness of the hot-melt ink must be good. In order to impart such special properties to the image-receiving layer, it is necessary to appropriately adjust the types of binders and various additives and their compounding amounts, as described later.

Various binders such as polycarbonate resin, acrylic resin, polystyrene resin, polyvinyl acetal resin, polyvinyl butyral resin can be used.

However, if there is a practical requirement for the image formed by the present invention (for example, the issued ID card is required to have a predetermined heat resistance), such requirement items should be satisfied. It is necessary to consider the type or combination of binders. Taking heat resistance of an image as an example, if heat resistance of 60 ° C. or higher is required, Tg should be taken into consideration in consideration of bleeding of a sublimable dye.
It is preferable to use a binder having a temperature of 60 ° C. or higher.

When forming the image receiving layer, it may be preferable to contain, for example, a metal ion-containing compound, if necessary. Especially when the heat transfer compound reacts with the metal ion-containing compound to form a chelate.

The secondary processability of the image receiving layer refers to the writing property with a magic ink, the laminating property which becomes a problem when protecting the formed image, and the like. In addition, fine particles such as silica are also effective as the release agent. When the secondary workability is not a problem, it is effective to use a curable silicone compound as a measure for preventing fusion.

To form the information carrier layer formed by format printing, "lithographic printing technology" published by Japan Printing Technology Association,
It can be formed using the general inks described in "New printing technology overview", "Offset printing technology", "Plate making / printing quick guide", etc.
It is formed by ink such as carbon in oil-soluble ink, solvent type ink, etc.

The format printing is performed by resin letterpress printing, planographic printing, silk printing, flexographic printing on the substrate, the image receiving layer used in the sublimation type heat-sensitive recording system, the outermost layer of the image recording material, and the image recording material layer having scale-like powder. And the like.

A) <Flake-like powder> The scaly powder (hereinafter referred to as scaly pigment) is a thin film coating that gives mica with reflectivity (high iris reflection) and is transparent in the visible region and has a refractive index of 2.0 or more. It is coated with a certain metal oxide or metal sulfide, for example, Sb2S
3, Fe2O3, PbO, ZnSe, CdS, Bi2O
3, TiO2, PbCl2, CeO2, Ta2O5, Z
nS, ZnO, CdO, Nd2O3, Sb2O3, Si
It is formed by coating a single layer of O and InO3 or coating two layers.

When the mica and the metal oxide film are combined, the difference in the refractive index between them is larger than 0.4, so that a large amount of incident white light is reflected, and at the same time, the sub-side at the interface between the mica and the metal oxide film. Since it causes refraction, it becomes highly iris reflective,
It works to promote the discoloration effect more effectively.

At this time, by controlling the film thickness of the metal oxide film that coats the mica, the film thickness that can be made into a scaly pigment having a high rainbow reflectivity of any color tone is 10 to 10000 angstrom, preferably 200. A film thickness in the range of up to 5000 angstroms is desirable because it provides high iris reflection in the visible range. Specifically, JP-A-6-145553

"Iriodin" is a stable inorganic scale pigment in which the surface of natural mica is coated with a metal oxide having a high refractive index such as titanium oxide and iron oxide, and is a titanium oxide layer having a high refractive index and a low refractive index. The light reflected at the boundary between the mica and the surrounding medium is what gives the pearl luster. In this "Iriodin", a specific color of the iris color can be emphasized by changing the film thickness of the coated titanium oxide. Such a scale pigment contains a vehicle and an additive in a mixture with a colorant. Add it to ink and use it.
