得ることはできるが、保存安定性に問題があった。Structure of conventional example and its problems Conventionally, this recording method has used a transfer body containing a highly stable dye for transfer printing of polyester fibers, but such a transfer body has a low sublimation property. The coloring power was poor, and it was difficult to obtain sufficient color density using the thermal energy of a normal thermal head. Furthermore, although ionic dyes containing highly sublimable color formers can provide sufficient color density, they have problems in storage stability.

。The substrate used in the present invention is not particularly limited, but polymer films are particularly useful. Examples: ester polymers such as polyethylene terephthalate, polyethylene naphthalate, and polycarbonate, amide polymers such as nylon, cellulose derivatives such as acetyl cellulose and cellophane, polyvinylidene heptanide, and ethylene 47-677. Propylene copolymers, fluorine polymers such as Teflon, ether polymers such as polyoxymethylene and polyacetal, olefin polymers such as polystyrene, polyethylene, polypropylene, and methylpentene polymers, polyimide, polyamideimide, polyetherimide, etc. imide-based polymers, etc. can be used. In particular, polyester-based polymers are useful because they are thin, have a certain degree of heat resistance, and are inexpensive. In addition, imide-based, amide-based, and other polymers whose substrates are more heat resistant than polyester polymers are useful because they have excellent heat resistance when the transfer body is used repeatedly or at high speeds.

す基準面Ｐがら突出するように構成される。As shown in FIG. 1, the heat-sensitive recording transfer body 1 is composed of a base 2, a slippery heat-resistant layer 3 provided on one surface thereof, and a coloring material layer provided on the other surface of the base. This coloring material layer is composed of a sublimable dye layer 4 containing a binder as necessary and non-sublimable particles 6, and a part of the non-sublimable particles 6 is arranged so that it protrudes from the reference plane P formed by the sublimable dye. It is composed of

The effect is significant when any point in the range 4δ surrounded by the 0 μm circle is occupied by other non-sublimable particles. Among these, particularly when other non-sublimable particles are present somewhere in the area surrounded by a circle with a radius of 2o/Im, it has a remarkable effect.

It has an especially excellent effect when m. That is, the appropriate particle size of the particles 5 is 0.1 to 100 μm, especially 1 to 10 μm.

損なわれない。In the present invention, the non-sublimable particles 6 do not necessarily need to be exposed beyond the sublimable dye layer, and as shown by the broken line in FIG. 3, the non-sublimable particles 6 are covered with the sublimable dye layer 4'. It is okay to be In this case, the reference plane 2 will be as shown in the figure. Even in this case, the effect of the non-sublimable particles described later is not impaired at all.

場合でもかわらない。Further, non-sublimable particles as shown in FIG. 4 are distinguished by broken lines in the figure and are regarded as two particles. The same applies to those having three or more protrusions. The effect of non-sublimable particles is not limited only when they are present on the substrate, but also when they partially penetrate into the substrate.

る。また、染料転写体をくり返し使用に耐えさせる。The binder has the following effects. That is,
Since a sufficient amount of sublimable dye is retained and the distance between the reference plane 2 and the image receptor 7 is made close, a sufficient recording density is imparted to the image. It also makes the dye transfer body durable for repeated use.

is smaller than 0.1 μm, the effect of the non-sublimable particles is not sufficient. Unfortunately, when h exceeds 100 μm, sublimation of the sublimable dye is hindered, and an image with sufficient recording density cannot be obtained. Here, h is the maximum height of the non-sublimable particles 5 measured from the reference plane l.

非昇華性粒子は少ない密度でスペーサの機能を果たす。In order to obtain good halftone image quality, the density of h on the transfer body depends on the size of the pixel, the smoothness and homogeneity of the substrate and image receptor, etc. As the smoothness and homogeneity of the substrate and image receptor increase,
Non-sublimable particles function as spacers at low density.

にとくに効果が高い。Regarding the shape of non-sublimable particles, spherical particles are particularly effective. This is because the individual spherical particles have exactly the same spacer function no matter how they are arranged relative to the dye transfer body. That is, as shown in FIG. 7, the distance between the base body 2 and the image receptor 7 does not change at all due to a change in relative arrangement. Among non-sublimable particles, metals, metal oxides or polymeric compositions are particularly effective due to their high rigidity or elasticity.

な転写などのために、低記録濃度から高記録濃度までの
広い範囲にわたって良好なプラックの画像を得ることは
きわめて困難であった。Note that even when multiple types of sublimable dyes are used, very unique effects are exhibited. That is, in order to obtain a plaque image using a sublimable dye, usually a plurality of types of sublimable dyes are used. However, due to uneven transfer of the dye due to direct contact between the dye layer and the image receptor, or preferential transfer of the dye near the image receptor, good plaque is not obtained over a wide range from low to high recording densities. It was extremely difficult to obtain images.

囲にわたって良好なプラックの画像が得られる。However, in a transfer body constructed using these together with non-sublimable particles, the uniform sublimation gradient of each dye helps the transfer to the image receptor, and preferential transfer of dyes existing near the image receptor is achieved. Therefore, each dye is evenly transferred to the image receptor. Therefore, good plaque images can be obtained over a wide recording density range.

画像が広い記録濃度の範囲において得られる。If at least one of the multiple types of dyes is selected from basic dyes (including colored dyes or color formers that develop color with electron acceptors) and at least one type is selected from disperse dyes, one image receptor is used. By appropriate selection of , a plaque with very good color tone and high recording density can be obtained. This is thought to be because the basic dye and the disperse dye have different die sites (dying points) and do not cause harmful interactions with each other in dyeing and color development. In addition, by combining appropriate types of dyes, good images of arbitrary hues can be obtained in a wide range of recording densities.

きい。Further, excellent effects are obtained when the volume ratio of non-sublimable particles to binder is within the range of 10-3 to 102. At lower ratios, the effect of the non-sublimable particles is not significant, and at higher ratios they are not sufficiently bound by the binder. Among these, a ratio of 10-2 to 10 is most effective.

イズが発生する。In addition, in order to fully demonstrate the function of a spacer, it is necessary that at least 3 non-sublimable particles exist per transfer substrate corresponding to each pixel, and if they are present below this density, they will not work as a spacer. The function is insufficient and noise appears in the image.

ねるためである。All of these materials have great mechanical strength and are not destroyed by the pressure of bringing the transfer member and receiver into close contact, for example.
suitable for achieving the objectives of the invention. In addition to the polymer compositions mentioned above, there are also polymer compositions with melting points or softening points of 100°C.
The above are particularly effective. This is because many of the sublimable dyes used have sufficient sublimation ability even at 100'C or lower, and polymer compositions that meet this condition will not be transferred to the image receptor, so high-quality transparent images can be obtained using dyes alone. It's because you don't get it.

により写真に近いフルカラー画像を得ることができた。For each of the magenta and yellow sublimable dyes, 6 parts by volume of the dye, 6 parts by volume of polysulfone, 100 parts by volume of monochlorobenzene, and 20 parts by volume of alumina particles with an average particle size of 6 μm were mixed in a paint conditioner using glass beads. The ink was adjusted by mixing for 30 minutes with an I-ner, and cyan, magenta, and yellow sublimable dyes were sequentially coated on the transfer substrate of Example 1 using a gravure printing machine (plate depth 3 o 11 m). and used as a transcript. By using this transfer body and recording three colors in a superimposed manner on the image receiving paper using a thermal head under conditions similar to the recording conditions described above, it was possible to obtain a full-color image close to a photograph.
