原体物質の反応によって発色する原理を利用した感圧複
写シートはよく知られている。(Prior art) Electron-donating color formers such as Crystal Violin Raphton and Hen's Illeucomethylene Blue, and electron-accepting color developers such as activated clay, phenol-formaldehyde condensates, and polyvalent metal salts of aromatic carboxylic acids. or a combination of a nickel carboxylic acid salt and N,N-dibenzyl-dithiooxamide, a combination of an organic iron phosphate salt and a metal salt such as lauryl gallate, and a ligand compound. Pressure-sensitive copying sheets that utilize the principle of color development through reactions of body substances are well known.
一般に、かかる感圧複写シートは、相分離法、界面重合

用されている。In general, such pressure-sensitive copying sheets include an upper sheet (CB) in which microcapsules containing a chromogen substance prepared by a method such as a phase separation method, an interfacial polymerization method, or a 1n-siLu method are coated on a support; A base sheet (CF) in which a support is coated with another chromogen substance that develops color by reacting with the original substance;
A medium-circumference sheet (CFB) in which the microcapsules and the chromogen material described above are coated on different sides of a support is put into practical use in appropriate combinations.
又、別に上記マイクロカプセルと色原体物質を積層或い
は混合層として支持体の同一面に塗布した所謂単体感圧
複写シートと呼ばれるものもあり、更にその単体感圧複
写シートの裏面にカプセル層を設け、上記下用シートや

等がある。In addition, there is also a so-called single pressure-sensitive copying sheet in which the above-mentioned microcapsules and chromogen material are coated as a laminated or mixed layer on the same side of a support, and a capsule layer is further coated on the back side of the single pressure-sensitive copying sheet. There is also a single pressure-sensitive copying sheet set in which the lower sheet and the middle sheet are appropriately combined.
通常、これらの感圧複写シートは、水性系の塗料を大型
の塗工機で支持体に塗布することによって製造されるが
、特殊な製造方法として、カプセルをインキ化し、印刷
機によってスポット印刷する方法がある。Normally, these pressure-sensitive copying sheets are manufactured by applying water-based paint to a support using a large coating machine, but a special manufacturing method involves converting the capsules into ink and spot printing using a printing machine. There is a way.
カプセルインキのスポラＩ・印刷は、高価なカプセル塗

がある。Capsule ink Spora I printing allows expensive capsule paint to be printed only on the necessary areas of the support, so compared to the method of applying water-based paint to the entire surface of the support with a large coating machine, for example, it is possible to print only partially on the support. It can be used in a variety of ways, such as producing copy sheets with different tones, and depending on the desired product, it can exhibit extremely excellent economical features. However, while the printing method has great advantages over the method using a coating machine, it still has some aspects that cannot be said to be sufficient depending on the method.

る。(Means for Solving the Problems) The present invention provides a transfer sheet obtained by flexographic printing a capsule ink containing a chromogen substance, and another chromogen substance that reacts with the chromogen substance to develop color. This method of manufacturing a pressure-sensitive copying sheet is characterized in that a plate having regular irregularities on the surface is used for printing capsule ink.

効に発色に使われる為、均一な発色性を示すものと考え
られる。(Function) Why is it possible to obtain a pressure-sensitive copying sheet that exhibits more uniform color development by using a plate with regular irregularities for flexographic printing of capsule ink than when using a plate with a conventional flat surface? Although it is only a matter of speculation as to whether the capsule ink on the plate is transferred to the paper, it weakens the ink's intrusion into the voids between the pulp fibers, as it would with a flat plate. If the capsules in the voids hardly contribute to color development, the phenomenon disappears, and the capsules present both on the pulp fibers and in the voids are effectively used for color development, so it is thought that uniform color development is exhibited. .
本発明に用いられる版としては、規則的な凹凸を有する
版であれば有効であるが、中でも５μ〜８００μ、更に
好ましくは３０μ〜３００μの範囲の凹凸を有するもの
が特に好ましい。因みに凹凸が５μ以下では発色の均一
さの点でフラット版に極めて近いものとなり、又８００
μ以上では版エツジ部へインキが堆積し易くなる。As the plate used in the present invention, any plate having regular irregularities is effective, but one having irregularities in the range of 5μ to 800μ, more preferably 30μ to 300μ is particularly preferred. Incidentally, if the unevenness is less than 5μ, the uniformity of color development will be very close to that of a flat plate, and
If it is more than μ, ink tends to accumulate on the edge of the plate.

A rubber plate is preferable in terms of effectiveness.
