記録する熱転写記録方法は公知である。Structure of conventional example and its problems Using a recording medium and a sheet-like transfer body having a heat-resistant base material on one side of which is a recording material to be transferred to the recording medium, the recording material and the recording medium are brought into pressure contact with each other. A thermal transfer recording method is well known in which a thermal head, which is one of the temperature raising means, selectively heats and writes on the recording material from the back side of the transfer body, and selectively transfers and records the recording material onto the recording medium.

ト固体材料を融解させ、紙等の記録媒体に記録材
料を選択的に転写記録する。 In this type of conventional thermal transfer recording method, the recording material consists of about 80 parts by weight of a hot-melt solid material whose melting point is about 65 to 85°C, which is much higher than room temperature (for example, 25°C), and about 20 parts by weight of a pigment coloring material. A sheet-like transfer body made of a mixed material is coated and layered on a thin heat-resistant base material such as capacitor paper or polyethylene terephthalate (PET) film. A thermal head having a resistive heating element is pressed against the recording material, and the heat generated by the heating element selectively heats and writes the recording material through the substrate to melt the hot melt solid material and write it onto a recording medium such as paper. Selectively transfer and record a recording material.

料の殆んど全てが一度に記録媒体に転写記録され
るという特徴をもつている。 This type of thermal transfer recording method is characterized in that temperature-raising writing on the recording material is controlled at a temperature lower than the melting point of the hot-melt solid material, that is, at room temperature. Since the temperature and writing are controlled from the back side of the recording material through the base material, melting of the hot melt solid material constituting the recording material starts from the side of the base material opposite to the recording medium. The melting progresses in the thickness direction of the recording material in response to the supplied thermal energy, and almost all of the recording material melted in the layer thickness direction occurs only when the recording material on the recording medium side is melted. It has the characteristic that it is transferred and recorded onto a recording medium.

いう本質的な問題点を含んでいる。 Therefore, the recording material is transferred and recorded discontinuously at a threshold value by supplying heating energy for writing at a temperature higher than a certain value based on the melting energy, which is suitable for binary density recording. This involves the essential problem that it is impossible to perform transfer recording with halftone recording at a continuous transfer recording density that corresponds to the heating energy.

のデジタル階調記録処理方式が検討されている。 For this reason, conventional transfer recording methods, such as the density pattern method and dither method, are used to accommodate the current expanding multi-gradation recording applications such as video image recording.
A digital gradation recording processing method for performing multi-gradation density recording using binary density recording is being considered.

い等の問題を残していた。 Against the background of such technical difficulties, one of the inventors of the present invention previously proposed a thermal transfer recording method capable of producing continuous analog gradation. This thermal transfer recording method achieves the desired purpose by applying and supplying a solvent capable of dissolving at least one kind of material forming the recording material onto the recording medium and/or the transfer body, and controlling the writing temperature by increasing the temperature. However, due to differences in the amount of applied solvent, the maximum recording density may be small, or the change in recording density with respect to recording energy may be steep.
Although continuous analog gradation is possible, there remain problems such as difficulty in controlling it.

An object of the present invention is to provide an improved analog gradation thermal transfer recording method that is easy to control and that enables transfer recording of monochrome images and full color images having halftones.

像品質の低下が防止できる利点がある。 As described above, in this embodiment, the desired pattern is recorded by overlapping transfer recording twice. As will be described in detail later, when the amount of coating solvent is large, a low recording density region is effectively recorded, and when the amount of coating solvent is small, a high recording density region is effectively recorded. Therefore, if the amount of coating solvent in the second coating step, which is the subsequent solvent coating step, is reduced compared to the first coating, bleeding of the recorded pattern and images due to the solvent of the transferred recording material in the high concentration range due to the coating solvent will occur. This has the advantage of preventing quality deterioration.

化が比較的急俊で階調記録制御には不利である。 The characteristics shown in Figure 4 are for the conventional one-time writing with a large amount of solvent, but in the low pulse side region,
The change in recording density D o with respect to the applied pulse width P w is gradual, which is advantageous for gradation expression. However, due to the excessive heat capacity caused by the presence of a large amount of solvent, it is difficult to raise the temperature above a certain level, so the thermal dissolution of the recording material does not proceed any further, and the saturated recording density is too low. In addition, characteristic 3 is the case where the amount of solvent is small in conventional writing once, and the saturated recording density is relatively high, but on the other hand, due to the insufficient amount of solvent, the change in recording density D o with respect to the pulse width P w is compared. It is very fast and is disadvantageous for gradation recording control.

調制御が容易なことを示している。 Characteristic 1 in FIG. 3 is a recording characteristic diagram according to this embodiment, and the problems of low saturation recording density and gradation recording properties shown in conventional characteristics 2 and 3 can be solved by controlling the amount of solvent coating and supplying. This was improved by writing the image twice, and the recording density was high and varied continuously from a low density area to a high density area, indicating that analog gradation is possible and gradation control is easy.

と思われる。 As is clear from the operating principle of this embodiment, characteristic 1 is approximated by the simple sum of the recording densities of characteristic 2 and characteristic 3, but the recording density Do is slightly lower. This is thought to be due to the difference in the way of transfer between recording on unrecorded recording paper and recording on previously recorded paper, or due to the unique characteristics of the coloring material and wax that constitute the recording material.
本実施例の特徴とするところは、溶媒の溶解力
を熱制御し、溶媒量を変え複数回重ね合せ書きす

質は問わない。 In the examples, the solvent was applied to the recording medium, but it may also be applied to the recording material of the transfer body, or both. The presence of a solvent is sufficient. Therefore, the recording medium is not limited to ordinary recording paper, such as plastic film or synthetic paper, which has a substantially uneven surface with a higher density than the element density of the thermal head on one side of a thin sheet. The material may be any material as long as it can hold the solvent.

溶媒塗布ローラーで触れることがなく記録画像の
鮮明さの点で有効である。 In this example, the solvent was applied to the recording medium twice, but as described above, a transfer body with unevenness was used, and the transfer body itself had the ability to retain the solvent, and the first solvent supply was applied to the recording medium. It can also be fed separately to the medium and the second time to the transfer body. This is effective in terms of the clarity of the recorded image since the surface of the recording medium, once recorded, is not touched by the solvent application roller.

ロ、すなわち二回目の溶媒塗布工程を省略しても
本実施例と同様の効果が得られ、この転写記録法
は工程上も簡略化され有用な方法である。 The amount of solvent supplied to the recording medium is very large (for example, the pressure on the solvent application amount adjuster is zero), and after the first transfer recording, the solvent does not completely evaporate and a small amount remains on the recording medium. When configured to perform the second transfer recording, the amount of solvent applied in the second time is zero, that is, even if the second solvent application step is omitted, the same effect as this example can be obtained, and this transfer recording method is advantageous due to the process. is also a simplified and useful method.
なお、上述の実施例における溶媒塗布量は、第
一回目に対して第二回目の溶媒塗布量を少なくし
たが、第一回目を少量、第二回目を多量にしても
よい。 In addition, in the above-mentioned example, the amount of solvent applied in the second application was smaller than that in the first application, but it is also possible to apply a small amount in the first application and a large amount in the second application.
また、実施例では、二回の重ね合せ転写記録を

By performing the transfer recording by changing the amount of the coating solvent, it is possible to obtain recording characteristics with even better recording density and gradation characteristics through this plurality of transfer recordings.

少なくできる利点がある。 In addition, in the embodiment, a case is shown in which a new transfer body is used for each transfer record, but from the second time onwards, the transfer body used for the first transfer record is used again for each of the first transfer records. Pulling it back to its original position and using it repeatedly has the advantage of reducing the consumption of the transfer body.

Corresponding alignment with the pattern already transferred and recorded on the recording material of the transfer body is not necessarily required, but sometimes this misalignment is recorded and displayed as a difference in shading in the transferred recording pattern on the recording medium. This may cause some inconvenience.

用の両面から推奨される。 In order to prevent these problems, a recording method that repeatedly transfers and records the transferred recording pattern on the recording medium and the corresponding pattern that has already been transferred and recorded on the recording material of the transfer body by correctly aligning each time, is as follows. Recommended from both the quality of the transferred recorded image and the effective use of the transfer material.

Even when used, by appropriately selecting the thermal solubility of the solvent material, a good gradation image can be obtained by performing the same transfer recording multiple times.

記録するとフルカラー画像の転写記録が行える。 In addition, although the embodiment has mainly explained the transfer recording of monochrome images, based on the principle of transfer recording described above, cyan, magenta, yellow, and even black can be added to the same substrate of the transfer body. Transfer recording of a full-color image can be achieved by providing primary color recording materials of three colors and four colors in regular order, aligning the respective recording patterns correctly, and overlappingly recording multiple transfer recordings corresponding to each primary color. .

再現にも優れている。 The transfer recording according to the present invention employs a wet method in which either or both of the binder material and the dye material constituting the recording material are heat-dissolved with a solvent material, so even if the surface condition of the recording medium is rough, it will not cause unevenness. Clear transferred recorded images with no blemishes can be obtained, and full-color color reproduction is also excellent.
