を用いた記録方法に関するものである。Detailed Description of the Invention The present invention provides a thermal transfer ink film (hereinafter referred to as an ink film) in which a porous network structure (hereinafter referred to as a porous network 5) is formed and a heat-melting ink is impregnated into this porous network.
This relates to a recording method using.

ている記録用紙に転写させることにより記録していた。Conventional thermal transfer recording methods produce in-phase,
Using an ink film coated with heat-melting ink that becomes liquid at high temperatures, the base material is heated by a thermal head to melt the ink and transfer it to recording paper that is in close contact with the ink surface. It was recorded by.
したがって、熱ヘッドで加熱された部分のインクはすべ
て溶融転写され、一画面記録したインクフィルムは記録

ガのようになる。Therefore, all of the ink in the area heated by the thermal head is melted and transferred, and the ink film recorded on one screen has no ink in the area corresponding to the recording surface, making it look just like a negative.
そのため、使用したインクフィルムを再度操り返、して
使うことはできないという欠点があった。Therefore, there was a drawback that the used ink film could not be recycled and used again.

ないためである。In recent years, ink films capable of repeatedly recording the same area have been developed and attracting attention for the purpose of improving economy and operability. A typical ink film is an ink film formed by forming a porous network and impregnating the porous network with a hot-melt ink. However, when this ink film is used by repeatedly recording the same portion, the density decreases significantly with respect to the number of repeated recordings, making it impossible to obtain the desired number of repeated recordings. This is because when the ink film is kept stationary and the same area is repeatedly recorded, the amount of ink remaining in the porous mesh decreases relative to the number of recordings, making it impossible to always record under the same conditions.
このような問題を軽減させる方法としては、熱ヘッドの

問題がある。Possible ways to alleviate this problem include increasing the heating energy of the thermal head with the number of repeated recordings, or improving the porous network, but the former would complicate the method of driving the thermal head, while the latter would There is a problem in establishing the manufacturing method.

いた記録方法を詳細に説明する。In order to eliminate these drawbacks, the present invention provides a recording method using a thermal transfer ink film in which a porous network is formed and the porous network is impregnated with a heat-melting ink.
The present invention is characterized in that the running speed of the thermal transfer ink film is lower than the running speed of the recording paper. The recording method using this close-up thermal transfer ink film will be explained in detail below based on the drawings.

A thermal head in which a heating resistor corresponding to a recording image signal generates heat by a drive circuit (not shown); 2 is an ink film formed by forming a porous network on a thin base material and impregnating the porous network with heat-melting ink; , 3 is a recording paper, 4 is a platen μm that rotates the ink film 2 and the recording paper 3 in close contact with the thermal head 1, and 5 is a feed that is rotated by a drive mechanism (not shown) and runs the recording paper 3 in the direction of the arrow shown in the figure. A roller 6 is a feed roller that rotates via a reduction gear from a drive mechanism for running the recording paper 3, and causes the ink film 2 to run in the direction of the arrow in the figure.

エネルギーによって若干異なるが、繰り返し記録回数に
対し濃度が大幅に低下する。The ink film 2 is impregnated with the VCC porous network ink as described above, and the content of this ink is K14.
g/m2, accounting for 70% of the total ink layer. FIG. 2 shows the measurement results of the density characteristics when recording was repeatedly performed with the Kamata ink film 2 fixed on the thermal head 1. In Figure 2, broken lines A, B, and C are 1 kan J/dot and 0.7 m J/dot +, respectively.
It also shows the transfer density with respect to the number of repeated recordings when coated paper with a smoothness of 1900 seconds at 1.7 mJ/dot is used. From this figure, although it varies slightly depending on the heating energy of the thermal head 1, the density decreases significantly with the number of repeated recordings.
したがって、所望する濃度の許容限界を１．０とすれは
、繰り返し記録回数は１〜２回程度になってしまう。Therefore, if the desired density tolerance limit is set to 1.0, the number of repeated recordings will be about 1 to 2 times.
この場合、記録用紙３は、原則的に紙質には制限されな

少な（て済むことがわかった。In this case, the recording paper 3 is not limited by the paper quality in principle, but the smaller the ink transfer amount Wr required for a certain density, the more advantageous it is to increasing the number of repeated recordings N, so the smoothness is higher. Paper is preferred. In other words, as a result of an experimental study on the relationship between ink transfer iWr and transfer density using paper quality and smoothness as factors, we found that the smoothness should be 1000 seconds or more (Beck smoothness) (particularly for coated paper, a constant density (1
, 0), the ink transfer amount W' required is as small as 1.4 g/m2.

なるように設定した。実際には記録用紙３の走行速度を
可変とすることが好ましくないので、Ｖｐを一定ＩＶ。By the way, in the recording method of the present invention, the ink film 2 is also caused to run together with the recording paper 3. That is, when the recording paper 3 is run by the feed roller 5, the ink film 2 is also run by the feed roller 6 at the same time. At this time, let the running speed of the recording paper 3 be ■, and let the feeding speed of the ink film 2 be f.
These running speed ratios n=V, /V, were set to be greater than 1. In reality, it is not preferable to make the traveling speed of the recording paper 3 variable, so Vp is set to a constant IV.

反比例する。FIG. 3 shows the transfer density determined based on the above recording method. From this figure, assuming that the allowable concentration limit is 1.0, j is approximately 7. Since this n has the same meaning as the number of repeated recordings N described above, the number of repeated recordings is greatly improved compared to the method of simply recording with the ink film 2 fixed (repeated recording times & in Fig. 2). It turns out. This is because the unused portion of the ink film 2 is always replenished, and the amount of replenishment is inversely proportional to the running speed ratio n.

The running speed, vf, was set to 1/7. We took recorded images of various patterns and investigated their density characteristics, and found that we were able to obtain clear recorded images with little change in density. The same number of recorded images were obtained with 1/7 the amount compared to film.

置の小形化が図れるという利点を有するものである。As explained above, in the recording method of the present invention, a thermal transfer ink film formed by forming a porous network structure on a thin base material and impregnating a heat-melting ink into the porous network structure is heated. In a thermal transfer recording method in which the heat-melting ink is melted by heating a head and a part of it is transferred to recording paper, the traveling speed of the thermal transfer ink film is made smaller than the traveling speed of the recording paper. , the unused portion of the thermal transfer ink film can be constantly replenished, and the number of repeated recordings can be greatly increased.Therefore, there is no need to control the heating energy of the thermal head or improve the porous network structure. Moreover, since the amount of thermal transfer ink film used is very small, it has the advantage of improving ease of use, operability, and making the device more compact.
