を剥離することによりマスクを作製して用いるマスキン
グフィルムが多用されている。[Prior Art] Conventionally, in the field of photolithography, when combining various original images or when trimming a part of an original image, a light-shielding film mainly composed of resin and dye is used on a transparent film support. A masking film is often used in which a mask is prepared by providing a removable film having a film, cutting it with a cutting blade, and then peeling off the desired portion on a light table while observing the cut lines.

困難である。[Problems to be Solved by the Invention] With conventional masking films, the cut lines are difficult to see on a light table, making peeling work difficult and requiring skill. Particularly in multi-color plate making, it is often the case that only a part of the cut design is peeled off, rather than the entire part. Peel it off and use it as a mask. At this time, it is necessary to cut as thin a line as possible so that the cut line that does not peel off opens and loses its light-shielding properties, and so that the position of the design does not shift. Therefore, when looking at the cut line on the light table, it is very difficult to see and peeling is difficult.

ムを提供するものである。[Means for Solving the Problems] The present invention provides a release method comprising at least two layers, a colored resin layer containing a binder resin and a light-shielding colorant, and a resin layer adjacent to the colored resin layer, on a transparent support. A light-shielding masking film having a color film, wherein the resin layer adjacent to the colored resin layer uniformly contains a resin that whitens under stress,
A light-shielding masking film characterized by a resin layer that has the property of reducing light transmittance around the cut line when cut with a cut blade, so that the cut line can be easily seen when cut with a cut blade. The purpose of this invention is to provide a masking film that can.
本発明において、応力で白化するとはカット刃により応
力がかかった部分にひび割れなどが起こり、反射光で見
る時には白く見え、透過光で見る時には光透過率が低下
して黒く見える現象を云う。In the present invention, "whitening due to stress" refers to a phenomenon in which cracks occur in the area where stress is applied by the cutting blade, and the area appears white when viewed under reflected light, and appears black due to a decrease in light transmittance when viewed under transmitted light.
また、応力で白化する樹脂を均一に含むとは、応力で白
化する単一の樹脂から成る層であるか、又は２種類以上
の樹脂を混合する場合には樹脂が相溶性を有することを
云う。Furthermore, "uniformly containing a resin that whitens under stress" means that the layer consists of a single resin that whitens under stress, or that the resins are compatible when two or more types of resin are mixed. .

実用に適さない。As mentioned above, the present invention is a light-shielding masking film having a peelable film composed of at least 2Fj, but if the resin that whitens under stress is uniformly mixed into the conventionally known single-scrap peelable film, Adding an amount that maintains film performance suitable for peeling work will not reduce the light transmittance around the cut line, and adding an amount that will reduce the light transmittance around the cut line will open the cut line and prevent light from entering. It is not suitable for practical use because it leaks and loses its light-shielding properties, and it also becomes impossible to obtain film performance suitable for peeling work.

光を散乱する。[Function] The light-shielding masking film of the present invention has a resin layer uniformly containing a resin that whitens under stress on top or bottom of the colored resin layer, so it can be cut by the stress applied to the blade when cutting. The resin turns white around the lines. Therefore, when observed on a light table, light is scattered around the cut line.
このため、カットしたマスキングフィルムの所要部分を
剥離する際に、カットした線が極めて見やすくなる作用
をなすものである。Therefore, when peeling off a required portion of the cut masking film, the cut line becomes extremely easy to see.
