本発明は、感光性印刷版を積み重ねる際の新規
な積み重ね方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel stacking method for stacking photosensitive printing plates.
従来、感光性印刷版は、種々の支持体に感光性
組成物を塗布し、それを規定のサイズに断裁し、
数枚又は数10枚を積み重ねて一単位の包装として
市販されてきた。この際、いずれも感光層の表面

定サイズに断裁するときに、スムーズに、しかも
精度良く行なわせる目的のために、いわゆる合紙
を入れて、密着させて積み重ねていた。 Conventionally, photosensitive printing plates are produced by applying a photosensitive composition to various supports, cutting it to a specified size, and
It has been sold commercially as a single unit package by stacking several sheets or several dozen sheets. At this time, in order to prevent the surface of the photosensitive layer from being scratched or damaged by friction, and to ensure smooth and accurate cutting to a certain size, a so-called interleaving paper is inserted to ensure close contact. I was piling it up.
合紙としては、紙、不織布、プラスチツクシー

合成樹脂、ワツクス、脂肪酸等を含浸させた耐水

せた耐水紙が特に良いとされていた。その理由と
して、紙のみの場合の合紙と比較して多量の枚数
を一度に断裁できることと、感光層面に湿気を与
えない等の長所があるからである。 As interleaf paper, paper, non-woven fabric, plastic sheet, paper coated with synthetic resin on one or both sides,
Waterproof paper impregnated with synthetic resin, wax, fatty acids, etc. was used. Recently, paper coated with synthetic resin on one or both sides, and waterproof paper impregnated with synthetic resin or wax have been considered particularly good as interleaving paper for photosensitive planographic printing plates. The reason for this is that it has the advantage of being able to cut a larger number of sheets at once compared to interleaving paper that is made only of paper, and that it does not introduce moisture to the surface of the photosensitive layer.

がシワ状になり、そのまま積み重ねると、感光層
を損傷させたり、そのシワ状模様が感光層に移
り、現像が不均一になる等の欠点があつた。 When using these interleaving papers, in order to prevent them from shifting when placed between printing plates, a high voltage is applied to the surface of the photosensitive layer before or after cutting during the manufacturing process of the photosensitive printing plates. They were charged with electricity and held in close contact. However, in such cases, high-voltage static electricity remains on the stacked sheets of paper, and users often receive electric shocks during work or when using the sheets. In addition, the adhesion between the photosensitive printing plate and the interleaving paper is too good, making it difficult to remove it easily. Sometimes the interleaf paper becomes wrinkled because it is pressed with a roller etc. when stacking the sheets, and if stacked as is, it may damage the photosensitive layer or the wrinkled pattern will be transferred to the photosensitive layer, resulting in uneven development. There were other drawbacks.

印刷版材用合紙が開示されている。この合紙によ
れば、天然パルプより成る紙に比べ、著しく裁断

シートに比べ、感光性印刷版材の使用時に容易に
はがすことができる。 For example, JP-A-55-88062 discloses interleaf paper for photosensitive printing plates in which paper contains wax in a solid content of 0.03 to 10%. This interleaf paper has significantly improved cutting properties compared to paper made of natural pulp, and can be easily removed when using a photosensitive printing plate material compared to a plastic sheet.
しかし、上記の紙にワツクスを含有させた合紙
には、次のような欠点があつた。 However, the above paper containing wax had the following drawbacks.
裁断性は天然パルプよりなる紙よりは良い
が、片面もしくは両面にプラスチツクを被覆し
た合紙と比較して悪く、裁断の際には裁断用の
刃を頻繁に交換しなければならない。 Although its cutting properties are better than paper made from natural pulp, it is poorer than paper coated with plastic on one or both sides, and the cutting blade must be replaced frequently when cutting.
裁断性が悪いために裁断面にバリが出やす
く、バリを20μ以下におさえることが難しい。 Due to its poor cutting properties, burrs tend to appear on the cut surface, making it difficult to keep burrs below 20μ.
僅かだが、他のものよりもコストが高い。 It costs a little more than others.
突き揃えがしずらく、そのために裁断ミスが
起こる場合がある。 It is difficult to align the sheets, which may result in cutting errors.

重ねる方法が開示されている。 In addition, JP-A-56-29243 discloses photosensitive printing using paper coated with plastic on one side as an interleaving paper when stacking photosensitive printing plates having a photosensitive layer on a metal support or their materials. A method of stacking plates, etc. is disclosed.

おいても良好な裁断性が確保される。 If the above-mentioned interleaf paper is used, since the charging time is limited, there is an advantage that a person stacking photosensitive printing plates or a plate maker will not be shocked by electric shock. Furthermore, good cutting performance is ensured even when a stack of a large number of photosensitive printing plates is cut using a guillotine or the like.
しかし、上記の紙の片面にプラスチツクを被覆
した合紙には、次のような欠点があつた。 However, the above-mentioned interleaf paper, in which one side of the paper was coated with plastic, had the following drawbacks.
密着が良すぎて、はがす時に感光膜面を損傷
させることがある。 If the adhesion is too good, the surface of the photoresist may be damaged when peeled off.
はがす時などに静電気が以上に発生し、感電
シヨツクを受ける。 When removing it, more static electricity is generated and you may receive an electric shock.
突き揃えが難しく、多数枚を一度に裁断する

くなる等の欠点があつた。 It is also known to spray a small amount of antistatic surfactant to prevent static electricity, but in this case, moisture remains on the surface of the photosensitive layer, and the retention of the photosensitive layer, which is mainly composed of diazo resin, is poor. There were drawbacks such as slow development and slow development.

る。 According to the present invention, since the solid powder exists between the surface of the photosensitive layer of the photosensitive printing plate material and the interleaving paper, the interleaving paper becomes slippery, and as a result, it is difficult to generate static electricity, thereby preventing electric shock. I no longer feel it. Furthermore, the interleaf paper can be easily peeled off, and the surface of the photosensitive layer is not damaged. Furthermore, when stacking several or tens of sheets and cutting them with a guillotine to a certain size, it becomes easier to align the plate materials, which improves dimensional accuracy. Another advantage is that even when the interleaving paper is removed, some solid powder remains on the surface of the photosensitive layer, so when the film original plate and the surface of the photosensitive layer are brought into close contact with each other in vacuum, they can be brought into close contact in a short period of time. No static electricity is generated between the photosensitive layer and the photosensitive layer surface, allowing for smooth film imposition work. In this case, it also has the advantage of being less likely to cause blurring or the like when exposed to light.

From about the 50th sheet onwards, the weight of the aluminum caused the paper to stick tightly to the surface of the photosensitive layer, making it difficult to remove, and when I tried to forcefully remove it, static electricity was generated and I received an electric shock. Also, at this time, the surface of the photosensitive layer was scratched and the photosensitive film was peeled off to some extent. Furthermore, when cutting into smaller sizes, it was difficult to align the sheets, resulting in poor workability.
The time required to vacuum adhere the negative film was 65
It was hot in seconds.
