Description
【発明の詳細な説明】 この発明は、エンボス版の製造方法に関する。[Detailed description of the invention] The present invention relates to a method for manufacturing an embossing plate.
ビニルレザー、ビニルペーハー、人造皮革、合成皮革、
人工皮革などの熱可塑性合成樹脂シートにエンボス加工

る。Vinyl leather, vinyl pH, artificial leather, synthetic leather,
Embossed sheet materials, which are made by embossing thermoplastic synthetic resin sheets such as artificial leather, are used for wallpaper, shoes, bags, bags, clothing, automobile seats, furniture seats, etc.
上記のエンボス加工に使用されるエンボス版は、金属板
または金属ロールの表面にレジスト腐食法、電気鋳造法
、母型取り法、ミルロール法などによって凹凸模様を形
成したものであるから、上記の凹凸模様の凸部の高さを
２段以上に形成することが困難であり、エンボス版が非
常に高価になると共に、比較的単調な凹凸模様しか得ら
れないという欠点があった。The embossing plate used for the above-mentioned embossing is a metal plate or metal roll with an uneven pattern formed on the surface by a resist corrosion method, an electroforming method, a master molding method, a mill roll method, etc. It is difficult to form the height of the convex portions of the pattern to be two or more levels, and the embossing plate becomes very expensive, and there are disadvantages in that only a relatively monotonous concavo-convex pattern can be obtained.
また、上記のエンボス版を用いてバレープリントを行な
う場合に、このエンボス版が金属製であるためエンボス
版に対するプリント用塗料の付着力がその表面張力に比
べて小さくなり、プリント用塗料がエンボス版上で接触
角の大きい水滴状になり、そのためプリント模様が不正
確になり、更に写真製版とは異なり網点によって濃淡を
表わすことが困難であった。In addition, when performing valley printing using the above embossing plate, since this embossing plate is made of metal, the adhesion force of the printing paint to the embossing plate is smaller than its surface tension, and the printing paint is attached to the embossing plate. The pattern formed on the surface of the film was shaped like a water droplet with a large contact angle, resulting in inaccurate printed patterns, and unlike photolithography, it was difficult to express shading using halftone dots.
また、硬質ゴムロールに手彫りまたは母型取りすること
によって凹凸模様を形成したエンボスロールが知られて
いるが、この場合にはゴム硬度を大きくすることが困難
であり、また精度が低くなるため、細かくシャープなエ
ンボス７Ｊ［が不可能であった。In addition, embossing rolls are known in which uneven patterns are formed by hand engraving or machining on a hard rubber roll, but in this case, it is difficult to increase the rubber hardness and the precision is low, so Sharp embossed 7J [was impossible.
一方、印刷用の版を製造する方法として、感光性合成樹
脂を使用する方法が知られている。On the other hand, a method using a photosensitive synthetic resin is known as a method for manufacturing printing plates.

法である。In other words, a photosensitive resin layer that is cross-linked and cured by light energy is formed on the base sheet, a negative is layered on this photosensitive resin layer and exposed to light, and the photosensitive resin layer is cured in a pattern that corresponds to the image on the negative. Thereafter, the resin in the uncured portion is eluted with a solvent, thereby forming an uneven pattern on the base sheet.
しかしながら、上記の感光性合成樹脂で製造された印刷
用の版は、凹凸模様が１段の樹脂層で形成されているの
で、エンボス加工用に使用したとしても平面的な模様し
か得られなかった。However, printing plates made from the above-mentioned photosensitive synthetic resins have uneven patterns formed by a single layer of resin, so even if used for embossing, only a flat pattern could be obtained. .
この発明は、凹凸模様の凸部の高さが２段以上に形成さ
れたエンボス版を容易に、かつ安価に製造することがで
き、バレープリントを行なう場合に正確なプリント模様

ができるエンボス版の製造方法を提供するものである。According to the present invention, it is possible to easily and inexpensively manufacture an embossing plate in which the height of the convex portions of a concave-convex pattern is formed at two or more levels, and when performing valley printing, it is possible to obtain an accurate printed pattern and to obtain a mesh pattern. The present invention provides a method for manufacturing an embossed plate that can express color shading using dots.

製造方法である。That is, in this invention, a negative is layered on a photosensitive resin layer formed on a base sheet and exposed to light to form a hardened area with a pattern corresponding to an image on the negative, and then the above operation is repeated using a negative with a different image. It is characterized by forming a multilayer photosensitive resin layer, and then dissolving and removing the uncured portion of the multilayer photosensitive resin layer with a resin-soluble solvent to form an uneven pattern with different heights on the base sheet. This is a method for manufacturing an embossing plate.
以下にこの発明方法の一態様を第１〜第４図によって説

A second photosensitive resin layer 3 is formed on the second photosensitive resin layer 3, and a second negative (not shown) having an image different from the first negative is overlaid and exposed to light. Note: Second stage cured portions 3a, 3b, 3c, 3d with a pattern corresponding to the second negative image are formed across both the resin layer 2 and the second photosensitive resin layer 3.
The transparent portion formed as the second negative image is connected to a part of the first-stage cured portions 2a, 2b, and 2c, or is not connected to the first-stage cured portions 2a, 2b, and 2c. It is something.

The third stage hardened portion 4a that is not continuous with the other portions does not form a stepped portion.
なお、この発明に使用する各種のネガは、上記の説明で
理解されるように、一つの原図を、所望する凹凸部を形
成するように３種の画像に分解して形成される。As understood from the above description, the various negatives used in the present invention are formed by dividing one original image into three types of images so as to form desired uneven portions.
