【考案の詳細な説明】
本考案は、アルミニウム板に予じめ感光剤を塗
布してなる版、即ち所謂PS版（以下PS版とい
う）の製版時に用いる遮光材に関する。[Detailed Description of the Invention] The present invention relates to a light-shielding material used when making a so-called PS plate (hereinafter referred to as PS plate), which is a plate formed by coating an aluminum plate with a photosensitizer in advance.
PS版の製版時に、露光してはならない領域を
覆うために遮光材が用いられるが、従来の遮光材
は殆んどが紙材の両面に遮光性の高い塗料を塗布
したものである。そのため、ピンホールが避けら
れず、このピンホール部が多く露光することによ
りPS版に焼付けられ、問題を起すことがあつ
た。 When making PS plates, light-shielding materials are used to cover areas that should not be exposed to light, but most conventional light-shielding materials are coated with highly light-shielding paint on both sides of the paper material. Therefore, pinholes were unavoidable, and when these pinholes were exposed to a large amount of light, they were printed onto the PS plate, causing problems.
本考案は、かかる問題点に鑑み、ピンホールが
なく完全に遮光できる遮光材の提供を目的とす
る。 In view of these problems, the present invention aims to provide a light shielding material that has no pinholes and can completely shield light.
本考案は、このため二層の金属薄膜層を接着剤
を介して接着し、各金属薄膜層にピンホールがあ
つてもこれを二層にすることによつてピンホール
を無くした遮光板を提供する。 For this reason, the present invention creates a light shielding plate that eliminates pinholes by bonding two metal thin film layers together using an adhesive, and even if there are pinholes in each metal thin film layer, this is made into two layers. provide.
前記金属薄膜層は、金属箔で構成しても良い
し、フイルム上に蒸着した金属蒸着膜で構成して
も良い。金属箔を用いる場合はアルミニウム箔が
製造工程及びコストの点から最も好適である。ア
ルミニウム箔は焼鈍を行なつた軟質のものでも、
焼鈍を行なわない硬質のものでも良く、厚さは５
〜30μのものが適当である。 The metal thin film layer may be made of metal foil or may be made of a metal vapor-deposited film deposited on a film. When using metal foil, aluminum foil is most suitable from the viewpoint of manufacturing process and cost. Even if the aluminum foil is soft and has been annealed,
A hard material that is not annealed may be used, and the thickness is 5
~30μ is suitable.
金属蒸着膜を形成した蒸着フイルムを用いる場
合は、フイルムとしてはポリエステルや塩化ビニ
ール等の合成樹脂からなる10〜100μのフイルム
が適当であり、蒸着膜の厚さは２枚合わせて600
Å以上にする必要がある。すなわち、金属蒸着膜
は者光性を持つけれども30〜400Å程度の厚さで
は充分な遮光性が得られない。そして、２枚の蒸
着フイルムを接着する際には蒸着膜の保護もかね
て蒸着膜側を合わせる様に接着する。 When using a vapor-deposited film with a metal vapor-deposited film formed on it, a film made of synthetic resin such as polyester or vinyl chloride with a thickness of 10 to 100 μm is suitable, and the total thickness of the two vapor-deposited films is 600 μm.
It is necessary to make it more than Å. That is, although the metal vapor deposited film has a light-shielding property, a sufficient light-shielding property cannot be obtained at a thickness of about 30 to 400 Å. When two vapor deposited films are bonded together, the two vapor deposited films are bonded together with their vapor deposited film sides aligned to protect the vapor deposited films.
接着剤としては種々のものを用いることができ
るが、溶剤系の場合はその使用量を２〜10ｇ／m2
として接着剤層の厚さを２〜10μとし、ポリオレ
フイン系の場合は10〜40μの範囲にするのが適当
である。 Various adhesives can be used, but in the case of solvent-based adhesives, the amount used is 2 to 10 g/m 2
As such, the thickness of the adhesive layer is preferably 2 to 10μ, and in the case of polyolefin, it is appropriate to range from 10 to 40μ.

さる様に接着剤層８で接着されている。 Next, an embodiment of the present invention will be explained based on the drawings. In Fig. 1, 1 and 2 are aluminum foils, which are bonded to each other via an adhesive layer 3, and whose outer surfaces are treated to have a satin finish. is used to prevent reflections. FIG. 2 shows an example using vapor-deposited films 4 and 5, each of which has an aluminum vapor-deposited film 7 formed on the surface of a synthetic resin film 6 such as polyester or vinyl chloride. The aluminum vapor-deposited films 7 are bonded together with an adhesive layer 8 so as to fit together.
