Description
産業上の利用分野
本発明は熱転写による記録に用いられる染料転
写体に関し、とくにサーマルヘツドやレーザービ
ームなどの電子デバイスにより高速記録に利用さ
れる。
従来例の構成とその問題点
従来この記録方法には、安定性に優れるポリエ
ステル繊維の転写捺染用染料を含有する転写体が
使用されていたが、かかる転写体は染料の昇華性
が低いため着色力が劣り、通常のサーマルヘツド
の熱エネルギーでは充分な色濃度を得ることは困
難であつた。又、昇華性の高いカラーフオーマー
を含むイオン系染料は充分な色濃度を得ることは
できるが、保存安定性に問題があつた。
一方、これらによる記録画像はとくに中間調の
領域での画質の乱れが問題になり、これらの主要
因はエネルギー印加部分の記録のぬけ(ドロツプ
アウト)とエネルギーを印加しない部分の染料の
昇華または飛散(ノイズ)によるものであること
がわかつている。
発明の目的
本発明は、安定で昇華能力に優れている色素を
用いて十分な色濃度を得、中間調領域でのドロツ
プアウトとノイズを低減させることにより、良好
な記録画質を与える染料転写体を提供することを
目的とする。
発明の構成
本発明は基体上に下記一般式()、()、
()で表わされる昇華性染料のうち少なくとも
1種と、非昇華性粒子とこれらを結着するバイン
ダーを有する色材層をもち、非昇華性粒子の一部
の非昇華性粒子が色材層の表面より突出し、且つ
この突出している任意の非昇華性粒子を色材層表
面に沿つて切断した断面において、非昇華性粒子
の断面の外周の各点から半径200μmの円で囲ま
れる範囲のどれかの点が他の非昇華性粒子で占め
られることを特徴とする染料転写体である。
(式中、Xは水素原子又はメチル基を、R及び
R′はそれぞれメチル基、エチル基、直鎖状もし
くは分岐鎖状のプロピル基又はブチル基を表わ
す)
実施例の説明
以下本発明の実施例について説明する。本発明
の基本構成を基体上に前記一般式、、で表
わされる昇華性染料のうち少なくとも1種類と、
非昇華性粒子とこれらを結着するバインダーを有
する色材層をもち、一部の非昇華性粒子が色材層
の表面より突出し、且つこの突出している任意の
非昇華性粒子を色材層表面に沿つて切断した断面
において、非昇華性粒子の断面の外周の各点から
半径200μmの円で囲まれる範囲のどれかの点が
他の非昇華性粒子で占められることを特徴とする
染料転写体である。
以下に実施態様例をあげる。
色材層が、前記一般式における置換基の異なる
2種以上の昇華性染料を含むこと。
一般式、、からそれぞれ選ばれた少なく
とも1種瑠ずつの昇華性染料を含む色相の異なる
3面の色材層を面順次に配置したこと。
一般式、、からそれぞれ選ばれた少なく
とも1種類ずつの昇華性染料を含む3面の色材層
と、一般式、、のそれぞれから少なくとも
1種類ずつ選ばれた染料を含む第4の色材層を面
順次に配置したこと。
色材層の表面より突出している非昇華性粒子の
色材層表面から突出した高さが0.1〜100μmの範
囲内にあること。
非昇華性粒子の熱伝導率が10-3cal/cm・s・
k以上であること。
基体の熱伝導率が10-3cal/cm・s・k以上で
あること。
このようにスペーサーとしての役割をはたす色
材層中の非昇華性粒子の存在により、色材層表面
と画像を記録する受像体面が必要以上の押圧力を
受けることがなく、中間調領域でのノイズを減少
させることができ、又、前記化学構造の昇華能力
と色相と安定性に優れた色素を色材層中に含むこ
とにより、記録濃度、色相の良好な銀塩写真に近
い安定な画像を得ることができる。
前記一般式()、()、()で表わされる昇
華性染料の具体例としては、以下のものがあげら
れる。

INDUSTRIAL APPLICATION FIELD The present invention relates to a dye transfer member used for recording by thermal transfer, and is particularly used for high-speed recording with electronic devices such as thermal heads and laser beams. Conventional structure and problems Conventionally, this recording method used a transfer body containing a highly stable dye for transfer printing of polyester fibers. 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 with storage stability. On the other hand, images recorded using these methods suffer from disturbances in image quality, especially in the intermediate tone area, and the main causes of this are drop-outs in the recording in areas where energy is applied and dye sublimation or scattering (dropouts) in areas where energy is not applied. It is known that this is caused by noise (noise). OBJECT OF THE INVENTION The present invention provides a dye transfer material that uses dyes that are stable and have excellent sublimation ability to obtain sufficient color density, and reduces dropouts and noise in halftone areas, thereby providing good recorded image quality. The purpose is to provide. Structure of the invention The present invention provides the following general formulas (), (),
The coloring material layer has at least one sublimable dye represented by (), non-sublimable particles, and a binder that binds these, and some of the non-sublimable particles are in the coloring material layer. In a cross section of any non-sublimable particles protruding from the surface of the coloring material layer, the area surrounded by a circle with a radius of 200 μm from each point on the outer periphery of the cross section of the non-sublimable particles. The dye transfer material is characterized in that any point is occupied by other non-sublimable particles. (In the formula, X is a hydrogen atom or a methyl group, R and
(R' represents a methyl group, an ethyl group, a linear or branched propyl group, or a butyl group, respectively) Description of Examples Examples of the present invention will be described below. The basic structure of the present invention is formed by applying at least one kind of sublimable dyes represented by the above general formula on a substrate,
It has a coloring material layer having non-sublimable particles and a binder that binds them, and some of the non-sublimable particles protrude from the surface of the coloring material layer, and any of the protruding non-sublimable particles are removed from the coloring material layer. A dye characterized in that, in a cross section cut along the surface, any point within a range surrounded by a circle with a radius of 200 μm from each point on the outer periphery of the cross section of the non-sublimable particle is occupied by other non-sublimable particles. It is a transcription body. Examples of embodiments are given below. The coloring material layer contains two or more kinds of sublimable dyes having different substituents in the general formula. Three coloring material layers having different hues each containing at least one type of sublimable dye selected from the general formula are sequentially arranged. Three color material layers each containing at least one type of sublimable dye selected from the general formula , and a fourth color material layer containing at least one dye selected from each of the general formula . are arranged in field sequential order. The height of the non-sublimable particles protruding from the surface of the coloring material layer is within the range of 0.1 to 100 μm. The thermal conductivity of non-sublimable particles is 10 -3 cal/cm・s・
Must be more than k. The thermal conductivity of the base is 10 -3 cal/cm・s・k or more. In this way, the presence of non-sublimable particles in the coloring material layer, which acts as a spacer, prevents the surface of the coloring material layer and the surface of the image receptor on which images are recorded from being subjected to more than necessary pressing force. It is possible to reduce noise, and by including the dye with the above-mentioned chemical structure with excellent sublimation ability, hue, and stability in the coloring material layer, stable images with good recording density and hue similar to those of silver salt photographs can be created. can be obtained. Specific examples of the sublimable dyes represented by the general formulas (), (), and () include the following.

The ink for forming the coloring material layer is produced by mixing a pigment represented by the general formula or with a resin having a high melting point or softening point, a solvent or a solvent such as water, and non-sublimable particles. be able to. As the resin for preparing the above ink,
Oil-based inks such as rosin-based, phenol-based, xylene-based, petroleum-based, vinyl-based, polyamide-based, nitrocellulose-based, alkylcellulose, alkylcelluloses, ether-based, ester-based, etc. may be used in ordinary printing inks. or water-based resins such as maleic acid-based, acrylic acid-based, casein, silica, glue, etc. can be used, but more specifically, polycarbonate, polysulfone, polyphenylene oxide polyarylate, cellulose derivative with a high melting point or softening point. etc. are particularly effective. In addition, solvents for ink preparation include alcohols such as methanol, ethanol, propanol, and butanol, cellosols such as methyl cellosolp and ethyl cellosolp, aromatics such as benzene, toluene, and xylene, esters such as butyl acetate, and acetone. , ketones such as methyl ethyl ketone and cyclohexanone, hydrocarbons such as ligroin, cyclohexane, and kerosene, and halogenated hydrocarbons such as dimethylformamide, methylene chloride, chlorobenzene, and chloroform. However, when using aqueous resins, It is also possible to use water or a mixture of water and the above-mentioned solvents. The substrate used in the present invention is not particularly limited, but a polymer film is particularly useful. For example, ester polymers such as polyethylene terephthalate, polyethylene naphthalate, and polycarbonate, amide polymers such as nylon, cellulose derivatives such as acetyl cellulose and cellophane,
Polyvinylidene fluoride, tetrafluoroethylene-hexafluoropropylene copolymer, fluorine polymers such as Teflon, ether polymers such as polyoxymethylene and polyacetal, olefins such as polystyrene, polyethylene, polypropylene, methylpentene polymers, etc. Imide-based polymers such as polyimide, polyamideimide, polyetherimide, 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 when the transfer body is used repeatedly or at high speeds because they have excellent heat resistance. To explain the role of non-sublimable particles with reference to Figures 1 and 2, 1 is a base, 2 is a coloring material layer composed of a sublimable dye, a binder, and non-sublimable particles 3, and the non-sublimable particles 3 are a coloring material. The non-sublimable particles 3 protruding from the surface l of the layer 2 and protruding from the surface of the coloring material layer are placed along the coloring material layer surface l (using the coloring material layer surface l as a reference plane).
It is configured such that when cut, any point in a range 2a surrounded by a circle with radius r = 200 μm from each point on the outer periphery of the cross section 3a of the non-sublimable particle 3 is occupied by other non-sublimable particles. be. Among these, especially when other non-sublimable particles are present somewhere in the area surrounded by the circle r = 20 μm, the effect is extremely large. In the present invention, non-sublimable particles are not necessarily larger than the coloring material layer. The non-sublimable particles 3 do not need to be exposed to the outside, and the non-sublimable particles 3 may be covered with a layer 2' consisting of a sublimable dye and a binder, as shown by the broken line in FIG. In this case, the surface l of the coloring material layer becomes as shown in the figure. Even in this case, the effect of the non-sublimable particles described later is not impaired at all. 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. Furthermore, as shown in FIG.
The height h from the surface l of the coloring material layer 2 is 0.1 to 100 μm
It shows good results if it is within the range of 1μm
It has an especially excellent effect when h10μm. Further, a suitable particle size of the particles 3 is 0.1 to 100 μm, particularly 1 to 10 μm. Next, the action of the non-sublimable particles 3 will be explained using the recording example shown in FIG. 5 using the thermal head 5. (1) Non-contact action Since the surface l of the coloring material layer 2 and the clay paper 5 do not come into direct contact, the dye does not transfer due to pressure or melting, and the dye transfers only by sublimation or vaporization, resulting in good transparency. give an image. (2) Heat conduction effect Heat applied from the thermal head 4 through the substrate is smoothly conducted to the dye near the non-sublimable particles themselves, helping to sublimate the dye uniformly.
Further, the binder allows the coloring material layer to retain a sufficient amount of dye, and the surface of the coloring material layer can be formed at a distance close to the clay paper 5, so that an image with high recorded density can be obtained. I can do it. The effect of non-sublimable particles is not limited only when they are present on the base, but also when they partially penetrate into the base. In addition, if there are no other non-sublimable particles within the outside shaded area in Figure 2, or if
is smaller than 0.1 μm, the effect of non-sublimable particles is not sufficient. Furthermore, when h exceeds 100 μm, sublimation of the sublimable dye is hindered, and an image with sufficient recording density cannot be obtained. The material constituting the non-sublimable particles is selected from metals, metal oxides, metal sulfides, graphite, carbon black, silicon carbide, minerals, inorganic salts, organic pigments, or polymeric compositions. Examples of highly effective methods are listed below. Metals: aluminum, silicon, germanium, tin, copper, zinc, silver, iron, cobalt, nickel,
Chromium and alloys based on chromium. Metal oxides: alumina, beryllium oxide, magnesium oxide, cuprous oxide, zinc oxide, indium oxide, tin oxide, titanium oxide, silicon oxide, iron oxide, cobalt oxide, nickel oxide, manganese oxide, tantalum oxide, vanadium oxide, oxide Tungsten, molybdenum oxide, and their compounds doped with impurities. Metal sulfides: copper sulfide, zinc sulfide, tin sulfide, molybdenum sulfide. Minerals: Magnesium minerals, lime minerals, strontium minerals, barium minerals, zirconium minerals, titanium minerals, tin minerals, phosphorus minerals, aluminum minerals (waxite, kaolin, clay) silicon minerals (quartz, mica, talc, zeolite, diatom) soil). Inorganic salts: carbonates or sulfates of alkaline earth metal elements (magnesium carbonate, calcium carbonate, strontium carbonate, barium carbonate, magnesium sulfate, calcium sulfate, strontium sulfate,
barium sulfate). Polymer composition: phenolic resin, melamine resin,
Urethane resin, epoxy resin, silicone resin,
Urea resin, diallyl phthalate resin, alkyd resin, acetal resin, acrylic resin, methacrylic resin, polyester resin, cellulose resin, starch and its derivatives, polyvinyl chloride, polyvinylidene chloride, chlorinated polyethylene, fluororesin, polyethylene, polypropylene , polystyrene, polyvinyl acetal,
Polyamide, polyvinyl alcohol, polycarbonate, polysulfone, polyether sulfone, polyphenylene oxide, polyphenylene sulfide, polyether ether ketone, polyamino bismaleimide, polyarylate, polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polyimide, polyamide Imide, polyaclonitrile, AS resin, ABS resin, SBR, and compositions based on these. All of these materials have high mechanical strength and are not destroyed by the pressure of bringing the dye transfer member and receiver into intimate contact, for example, and are suitable for achieving the objectives of the present invention. In addition to the above-mentioned polymer compositions, those having a melting point or softening point of 100° C. or higher are particularly effective. This is because many of the sublimable dyes used have sufficient sublimation ability even below 100°C, 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. This is so that you can be saved. Furthermore, the thermal conductivity of non-sublimable particles is 10 -3 cal/
When the temperature is cm·s·k or more, the heat conducted from the substrate to the non-sublimable particles is smoothly transferred to the dye near the non-sublimable particles, which helps the dye to sublimate uniformly and improves the image quality. In addition, the thermal conductivity of the base is 10 -3 cal/
A similar effect is given when the distance is cm・s・k or more. Example 1 Sublimable dyes represented by the first, second, and third structural formulas were each 5 parts by volume, 5 parts by volume of polycarbonate, 100 parts by volume of dichloromethane, and an average particle size of 5 μm.
The silica particles were mixed in varying amounts and stirred separately in a ball mill, and the dispersion was applied onto a heat-resistant 9 μm polyester film using a wire bar to obtain three-color transfer bodies. (Here, the first formula is cyan, the second formula is yellow, and the third formula is magenta.) Three types of emulsions A, B, and C prepared below were mixed in appropriate proportions on polyprolene synthetic paper, and the mixture was coated with a wire bar to a thickness of 5 μm and dried to prepare an image receptor. Coating liquid A: Polyester (product name Vylonal)
20% by volume aqueous dispersion B: 20% by volume aqueous dispersion of polyethylene C: 20% by volume aqueous dispersion of silica with an average particle size of 20 mμ The coated parts of the transfer member and image receiver are brought into close contact with each other facing each other, and thermal The head was used to draw a recorded image of the dye. The recording conditions were as follows. Main scanning and sub-scanning density: 4 dots/mm Recording power: 0.7 W/Dot head heating time: 8 ms Table 1 shows the number of dropouts and noise per 1000 dots, and any silica particles present in the dye transfer material. Length of the maximum distance dpi between the projected figures between pi and particles existing in its vicinity
Indicates max (dpi). Figure 6 shows the relationship between particle arrangement and dpi. Dpi was determined from scanning electron micrographs taken perpendicular to capacitor paper. In addition, h defined in Fig. 1 was determined from scanning electron micrographs of the cross section of the dye transfer material, and was found to be 7 μm in all cases with different amounts of silica particles.
It was below. In addition, as a comparative example, the results when silica is not blended are shown.

Using the pigments represented by (1) = 2 parts by volume, (4) = 2 parts by volume, and (5) = 1 part by volume, ink was prepared, a transfer body was created, and transfer recording was performed in the same manner as in Example 1. A cyan record with a color density of 1.5 was obtained. Comparative Example Instead of the mixed dye used in Example 3, the following dye (CI Disperse Blue 60) was used. Using 5 parts by volume, the ink was adjusted, a transfer body was prepared, and transfer recording was performed in the same manner as in Example 1, but the color density of the cyan color obtained was 0.5 or less. It can be seen from the above examples that the images obtained using the dye transfer material of the present invention have good image quality with far less dropout and noise than the comparative examples and excellent color density and color reproducibility. In addition, dye transfer bodies having other non-sublimable particles according to the present invention other than these Examples also gave good results. Note that full-color images can also be obtained using three types of dye transfer bodies that generate cyan, magenta, and yellow. Effects of the Invention As described above, the dye transfer member of the present invention provides recorded images with reduced dropouts and noise and good image quality.
