Field of the Invention The present invention relates to a recording method (particularly, a full-color image recording method in which a recording liquid is ejected as droplets from a recording section by selective heating according to image information and is transferred to an opposing photographic paper). And a recording liquid used in this method.

分類できる。2. Description of the Related Art In recent years, as colorization of video cameras, computer graphics, etc. has progressed, the need for colorization of hard copy has been rapidly increasing. On the other hand, color hard copy systems such as a sublimation type thermal transfer system, a melt thermal transfer system, an inkjet system, an electrophotographic system, and a heat development silver salt system have been proposed. Among these recording methods, methods for easily outputting high-quality images with a simple device can be roughly classified into a dye diffusion thermal transfer method and an inkjet method.

The transfer dye is thermally transferred according to the amount of heat applied to.

注目を集めている。The above operation is performed by subtracting the three primary colors, namely,
The so-called thermal transfer method, which is characterized by obtaining a full-color image with continuous gradation by repeating each of the image signals decomposed into yellow, magenta, and cyan, is compact, easy to maintain, and instant. It is attracting attention as an excellent technology for obtaining high-quality images comparable to silver salt color photographs.

要部の概略正面図である。FIG. 2 is a schematic front view of the main part of such a thermal transfer type printer.

The recording paper (transferred material) 20 provided with the resin coating layer 20a is sandwiched, and these are pressed against the thermal head 1 by the rotating platen roller 3 and run.

The transfer is carried out in a dot shape on the dyeing resin layer 20a of the transfer target 20, and thermal transfer recording is performed. For such thermal transfer recording, a serial method in which a thermal head is scanned in a direction orthogonal to the traveling direction of the recording paper 20, or one thermal head is fixedly arranged orthogonal to the traveling direction of the recording paper. The line method is used.
【０００８】しかし、この方式はインクシートの使い捨
てに起因する多量の廃棄物の発生と、高いランニングコ
ストが大きな欠点であり、その普及が妨げられている。However, this method has a major drawback in that a large amount of waste is generated due to the disposable use of the ink sheet and a high running cost, and its spread is hindered.
【０００９】このように、従来の熱転写方式は高画質で
あるが、専用印画紙と使い捨てのインクリボン又はシー

【００１０】熱現像銀塩方式も高画質であるが、やはり

い。The heat-developable silver salt method also has high image quality, but the running cost is high and the apparatus cost is also high because the exclusive printing paper and the disposable ink ribbon or sheet are used.
【００１１】こうしたノンインパクト記録法は、記録時

Among them, the so-called ink jet recording method is capable of high-speed recording and can be recorded on so-called plain paper without requiring a special fixing process. Therefore, in recent years, it is extremely effective as a technique for hard copying images such as computer graphics. It is becoming a recording method.

Recording is performed by methods such as electrostatic suction method, continuous vibration generation method (piezo method), thermal method (bubble jet method), etc. according to image information, as shown in -59911 and Japanese Patent Publication No. 5-217. A small droplet of liquid is ejected from a nozzle provided on a recording head and adhered to a recording member to perform recording.
【００１３】従って、インクシート等を使用する場合の

は低い。最近では、特にサーマル方式が簡易にカラー画
像を出力できることから、普及が拡大している。Therefore, there is almost no generation of waste as in the case of using an ink sheet or the like, and the running cost is low. Recently, in particular, the thermal method is capable of easily outputting a color image, so that the spread thereof is expanding.
【００１４】しかしながら、従来、インクジェット記録
に用いられてきた記録液は、酸性染料等の水溶性染料を

め、記録画像に耐水性がないという問題があった。However, since the recording liquid conventionally used for ink jet recording is a water-soluble dye such as an acid dye dissolved in a mixture of water and a water-soluble organic solvent, the recorded image has no water resistance. There was a problem.
【００１５】これを改良するために、疎水性の染料を用

It does not run off the recording paper. Then, the disperse dye or the oil-soluble dye also develops color on plain paper.This is because the dialkyl phthalate ester, which is a liquid medium, is transferred at the same time as the dye and adheres to the paper, which serves as a coloring aid for the disperse dye. is there.

For this reason, when this recording liquid is used, it is possible to transfer it to PPC paper, and it is possible to form a high quality image. Also, the dye concentration of the recording liquid was 5% by weight at most in the past, but in the recording liquid composed of the above combination,

記録を行うことができる。As the energy for forming the recording material into droplets, irradiation with a heating beam such as laser light may be used instead of the heating method such as resistance heating. To improve the heating efficiency, a conductive material can be added to the recording material. Although a heating element and a laser can be combined for heating, in this case, good recording can be performed even if the power of each heating means is lowered.

In the recording method in which the liquid droplets are generated by changing the temperature and the liquid droplets are transferred to the recording medium disposed opposite to the recording liquid heating unit. An aromatic ester and / or an aromatic hydrocarbon having a boiling point of 150 ° C. or more that dissolves or disperses 5% by weight or more of the dye at 50 ° C. or less is used as the recording material, and a dye having a residue of 10% by weight or less is vaporized. Since the recording liquid containing each of the substances is used, the dye is sufficiently dissolved or dispersed, and a high-boiling point hydrophobic aromatic ester and / or aromatic hydrocarbon is used as a solvent,
It is possible to form a good image that suppresses the change in the recording liquid concentration and does not dissolve even when it comes into contact with water, and therefore does not flow down from the recording medium. Disperse dyes or oil-soluble dyes also develop color on plain paper because the phthalic acid ester, which is a liquid medium, is transferred at the same time as the dyes and adheres to the paper, which serves as a color development aid for the disperse dyes.
