写記録装置に関する。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a thermal transfer recording paper and a thermal transfer recording device using the same, and particularly to a thermal transfer recording paper and the same that are excellent in color recording, high-speed recording, and high-resolution recording. The present invention relates to a thermal transfer recording device using.
近年、オフィスオートメーションの発展に従がい、普通
紙に記録可能な記録装置が要求されている。In recent years, with the development of office automation, there has been a demand for recording devices that can record on plain paper.
この代表例が熱転写記録装置であり、現在、カラー記録
、高速記録、高解像度記録を０指して、更に開発が進め
られている。A typical example of this is a thermal transfer recording device, which is currently being further developed for color recording, high speed recording, and high resolution recording.

は、複数色のインクを重ねてカラー記録を行った場合、
第１図（ａ）に示されるように、画点のカケ、あるいは
第１図（ｂ）に示されるように画点のヌケが生じる。Thermal transfer recording devices perform recording using the simple principle of melting or softening ink with heat and transferring it to recording paper, so they have a simple structure and are maintenance-free. Since image quality is determined by accuracy, it is necessary to perform ink transfer accurately. However, when thermal transfer recording is performed at high speed, or when color recording is performed by overlapping multiple color inks,
As shown in FIG. 1(a), missing pixels occur, or as shown in FIG. 1(b), missing pixels occur.
更に高解像度記録では、著しく文字の鮮明さに欠ける。Furthermore, in high-resolution recording, the clarity of characters is noticeably lacking.
カラー画像の色ムラが生じるなどの問題が生じている。Problems such as color unevenness in color images occur.
この問題を解決するためには、用紙の平滑性を増せばよ
いということが一般的に知られて９る。It is generally known that in order to solve this problem, the smoothness of the paper should be increased.
すなわち、用紙が平滑であればあるほど、インクの転写
が効率よく行われると言われている。しかし、本発明者
が実験を行ったところ、高い平滑を有する用紙では、逆
に、インクの用紙への転写が不確実になってしまった。In other words, it is said that the smoother the paper, the more efficiently ink is transferred. However, when the present inventor conducted an experiment, it was found that ink transfer to the paper became unreliable when paper had high smoothness.
この発明（マ、以上の欠点を除去し、高速記録、カラー
記録の際にもインクが確実に転写されうる熱転写記録用
紙及びこれを用いる熱転写記録装置を提供することを目
的とする。It is an object of the present invention to eliminate the above-mentioned drawbacks and to provide a thermal transfer recording sheet on which ink can be reliably transferred even during high-speed recording and color recording, and a thermal transfer recording apparatus using the same.

この発明に先立ち、本発明者は、〔発明の技術的背景と
その問題点〕で述べたように、高平滑度の記録用紙を用

プを確実にするためには有用であるが、付着ステップで
は必ずしも有用でないと考えられる。Prior to this invention, as stated in [Technical background of the invention and its problems], the inventor discovered the following based on the fact that when recording paper with high smoothness is used, ink transfer becomes uncertain. I made a similar inference. That is, the transfer of the ink to the paper takes place in the desired transfer area, (1) the ink and the paper come into contact (this is called a contact step), and after the ink is heated (2) the cohesive force of the ink to the paper or the ink is the carrier of the ink. It has a stronger adhesion force than the adhesion force to the film (called the adhesion step), and is achieved by peeling off the paper and the ink ribbon. Improving smoothness is useful for ensuring the contact step, but It is believed that it is not necessarily useful in the deposition step.
この付着ステップを支配する因子を考察したところ、第
２図（ａ）に示されるように、用紙２１表面が滑らかで
あるよりも、第２図（ｂ）に示されるように、適当な粗
さを有している方が、インク付着力が向上するという結
論に至った。When we considered the factors governing this adhesion step, we found that rather than having a smooth surface as shown in FIG. 2(a), we found that the surface of the paper 21 should have an appropriate roughness as shown in FIG. It was concluded that the ink adhesion is improved when the ink has the following properties.
更に、熱転写記録においては、インク担体と記録用紙と
を圧接状態にして記録を行うことから、所定の抑圧下に
ある時に、用紙表面に実現される粗さが重要であると思
われる。以上の点に着目し、本発明はなされたものであ
る。Furthermore, in thermal transfer recording, since recording is performed with the ink carrier and the recording paper in pressure contact, the roughness achieved on the paper surface when under a predetermined suppression is considered to be important. The present invention has been made by paying attention to the above points.
ここでいうベック平滑度とは、ＪＩＳＰ８１１９に規定
されるように、所定面積の被測定表面と理想的な平滑面
との間に所定量の流体を流し、これが全て流出する時間
によって定義される。単位は秒である。このベック平滑
度によって示されるのは、用紙表面の全体的な滑らかさ
である。As defined in JISP8119, Bekk smoothness here is defined by the time it takes for a predetermined amount of fluid to flow between a surface to be measured of a predetermined area and an ideal smooth surface, and for all of the fluid to flow out. The unit is seconds. This Beck smoothness indicates the overall smoothness of the paper surface.
これに対し、プリントサーフラフネスは、抑圧下におけ

ラフネスとする。On the other hand, print surf roughness indicates the degree of local unevenness of the surface under suppression, and is measured as follows. That is, as shown in FIG. 3, an air inlet 31 adjusted to a low pressure, an air outlet 32 connected to a flow meter (not shown), a measurement head 34 having a partition wall 33 of a predetermined area, and a predetermined Paper 3 between the back support stand 350 hardness
6 is placed so that the ink-receiving surface faces the measuring head 34, and the measuring head 34 and the back support stand 35 support the paper 36.
By applying a constant pressure to the paper and measuring the amount of air leaking from the air inlet 31 to the air outlet 32 through the partition wall 33 for a certain period of time, minute surface roughness on the paper surface under pressure can be detected. This value is called the print surf roughness.

の付着力も強いものとなる。According to this invention, the surface not only has high smoothness but also locally has minute irregularities, so that when ink is transferred, the ink and paper come into close contact, and the adhesion between the ink and paper increases. It also becomes stronger.

Adhesives made from water-insoluble polymers such as urethane resins, vinyl acetate-ethylene copolymers, ethyl cellulose, and petroleum resins, or vegetable waxes such as carnauba wax and book wax, and animal waxes such as beeswax and serratus wax. It is made by using solid waxes such as petroleum waxes such as synthetic waxes, microcrystalline waxes and paraffin waxes, and synthetic waxes such as oxidized waxes and ester waxes. The requirements for the adhesive are film-forming properties and low surface energy, preferably 40 dyn 7 cm or less. The proportion of solid wax to adhesive is between 5 and 50%, preferably between 5 and 25%. This is 5
This is because if the amount is less than 50%, the effect of wax blending will be reduced, and if it is more than 50%, problems will occur in film forming properties.

たインクにより不均一になる場合、特に生じ易い。The thermal transfer recording paper according to the present invention has a Beck smoothness of 300 seconds or more and 2500 seconds or less, and a print surf roughness of 0.6μ.
more than 5 μ or less, preferably Bekk smoothness of 500 seconds or more 2
000 seconds or less, print surf roughness 0.8μ or more 3
It has surface properties less than μ. This is because when the Bekk smoothness is less than 300 seconds and the print surf roughness is more than 5μ, the contact of the ink to the paper becomes uneven, causing chipping of the image dots, etc.
When the time is 2500 seconds or more and 0.6μ or less, the adhesion of the ink is not enough for a year, and the ink often remains untransferred. This is particularly likely to occur when the paper surface becomes uneven due to previously transferred inks, such as in a color thermal transfer recording device that creates a color image by sequentially transferring a plurality of inks onto paper.

ボン７０と記録用紙７６は等速で搬送される。Next, the recording operation of the apparatus will be explained. Next, the recording operation of the device will be explained. When the start signal is input, the ink ribbon sensor 79 detects yellow ink and sets the ink ribbon so that its tip is positioned at the heat generating element array of the thermal head 63. At this time, the recording head assembly 66 is in a state separated from the platen roller 69, and only the ink ribbon 70 is transported by the drive of the ink ribbon take-up roll 75. After that, the recording head assembly 66 is lowered, and the thermal head 63 and ink ribbon 7 are lowered.
0, the recording paper 76 and the grating roller 69 are brought into pressure contact, and the recording preparation is completed. Recorded information source (not shown)
The drive circuit (not shown) of the thermal head 63 is driven by the recording signal corresponding to the yellow recording, and the heating element has a pulse width of 1 ms (maximum), a pulse period of 2 ms, and a pulse frequency of 70 mm.
It selectively generates heat with an exothermic energy of mJ/M. Since this thermal head 63 is capable of driving all heating elements, the ink ribbon 70 and the recording paper 76 are conveyed by 1/12 every 2 ms without shifting due to the rotation of the platen roller 69. Further, the driving of the thermal head 63 is controlled so that the heat generation temperature of the heating element remains constant regardless of the amount of distributed signals. The partially adhered ink ribbon 70 and recording paper 76 are separated by a peeling roller 65, and the ink is transferred to the recording paper. At this time, ink ribbon 70
is stretched by the drive of the ink ribbon take-up roll 75 to prevent flapping of the ink ribbon 70, which causes folding and poor transfer. In this way, one screen is first recorded using yellow ink. During this time, the ink ribbon 70 and the recording paper 76 are transported at a constant speed.

て行なう。同様にシアン記録ブラック記録を行なう。'After the yellow recording is completed, the recording head assembly 76 is separated from the platen roller 69. The recording paper 76 causes a step motor connected to the platen roller 69 to rotate in reverse at double speed. By moving the recording paper 76 backward by the same number of forward steps, the recording paper 76 is set at the initial position. During this time, magenta ink is set on the ink ribbon 70 by driving the ink ribbon take-up roll 75. After the ink ribbon 70 and recording paper 760 have been set, the recording head assembly 66 is lowered and the thermal head 63, ink ribbon 70, recording paper 76, and platen roller 69 are brought into pressure contact again, completing magenta recording preparation. Similar to yellow recording, the thermal head 63 is driven by a recording signal corresponding to magenta recording from a recording information source (not shown), and magenta ink recording is superimposed on yellow recording. Similarly, cyan recording and black recording are performed.

凸が存在している。Here, the ink transfer state in the example will be further described in a false manner. Figure 7 shows l[i! First color ink 8 on recording paper 76
This shows a state where the second color ink 82 is about to be transferred after the transfer of 0 is completed. Since the recording of the first color has been completed, there is a spot pressure of the ink 80 on the recording paper 76. Here, for example, if a second color ink 82 is to be transferred between the first color ink 80, the object to be transferred is a composite of the recording paper 76 and the ink 80, The surface has larger irregularities than the surface of the recording paper 76 alone.

カニズムでおる。Naturally, if this ink 82 is used, the state of contact between the ink 80 and the recording paper 76 is not favorable, and the ink 82 is pressed against the recording paper 76 with a weaker pressure. However, if the print surf roughness of the recording paper 76 is an appropriate value, the ink 82 and the recording paper 76 will be compatible and wet, and even with a weak pressure, the recording paper 76 and the ink 82 will be more reliably connected. For close contact. This is the mechanism for improving image quality.
