本発明は、主として写真製版において所要部分をカッテ
ィングし、透明画像を形成するために用いられる遮光性
マスキングフィルムに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a light-shielding masking film used primarily for cutting required portions in photolithography to form transparent images.
従来、プラスチック支持体上に透明性の遮光性剥離層を

ものは、写真製版等の分野において、所望の透明画像を
得るために、その遮光性剥離層に、人手又は機械により
カットラインを施し、そしてこのカットラインに応じて
遮光性剥離層を剥離させる。Conventionally, light-shielding masking films in which a transparent light-shielding release layer is provided on a plastic support are known. In the field of photoengraving, etc., in order to obtain a desired transparent image, a cut line is made on the light-shielding release layer by hand or machine, and the light-shielding release layer is peeled off according to the cut line. .
ところで、このようなマスキングフィルムにおける遮光

たマスキングフィルムは、これにカットラインを施し、
剥離作業を行う場合に、長時間その作業に従事すると、
非常に目が疲れやすく、作業効率が低下するという欠点
があった。By the way, the light-shielding release layer in such a masking film generally obtains the light-shielding effect by adding a colorant, but in the past, most of the colorants used to obtain the light-shielding effect were red-based. A masking film that uses a red colorant and does not contain a green colorant has a cut line on it.
When performing stripping work, if you engage in the work for a long time,
This had the disadvantage that it caused eye fatigue and reduced work efficiency.
一方、グリーン系統の色は、赤色系統の色とは異なり、

It is clear that the use of green colorants, which are known to reduce eye fatigue, significantly improves the drawbacks seen when using red colorants. However, unlike the case of red colorants, green colorants are significantly inferior in light shielding effect, and even if a reprinted green colorant is used, a practical masking film cannot be obtained.

れる。According to the present invention, in a transparent support provided with a transparent light-shielding release layer containing a colorant, the light-shielding release layer contains a yellow colorant having a maximum light-shielding wavelength of at least 480 nm and a blue colorant. Contains a mixed coloring agent consisting of a coloring agent to color the overall color tone in a greenish color, and has a light transmittance peak in the wavelength range of 540 to 570 nm, and blocks wavelengths of at least 480 nm or less. In addition, the amount of light transmission in the wavelength range of 480 to 700 nm (
Provided is a light-shielding masking film characterized in that the ratio (Y, /Y,) of the amount of light transmitted (Yl) in the wavelength range of 480 to 600 nm to Y2) is maintained at 60% or more.

に十分なグリーン系統色が得られなくなる。The masking film of the present invention has wavelengths of 540 to 570.
A masking film that has a light transmittance peak in the nm range, but if the light transmittance peak deviates from this range, it uses a conventional colorant to have a light blocking effect at wavelengths of 480 nm or less and exhibits a sulclean color tone. becomes extremely difficult to obtain. In addition, if the ratio of the amount of light transmitted in the wavelength range of 480 to 700 nm to the amount of light transmitted in the wavelength range of 480 to 600 nm is less than 60%, the masking film will have a yellowish tone, reducing eye fatigue. It becomes impossible to obtain a sufficient greenish color.

It can be obtained by laminating a light-shielding release layer having the above-mentioned light transmitting properties on a transparent plastic film such as a polyester film. in this case,
The light-shielding peeling layer i1'i contains, in addition to the above-mentioned mixed colorant, a polymeric substance such as synthetic rubber or synthetic resin as a binder component, but the specific structure of the light-shielding peeling layer is not well known. It can be constructed according to conventionally known techniques. Examples of the composition constituting this light-shielding release layer include nitrile rubber, vinyl chloride-vinylidene chloride copolymer, colorant, and optional additives, or nitrile rubber, vinyl chloride-vinylidene acetate copolymer. The amount of the colorant added is usually 2 to 50% by weight in the light-shielding release layer.
, preferably 5 to 30% by weight, so as not to impair the transparency of the light-shielding release layer.
