<p>PURPOSE:To distinctly discriminate a cutting line by incorporating a fluorescent material into a light shieldable release layer provided on a plastic film base so that the cutting line formed on the light shieldable release layer generates fluorescence. CONSTITUTION:This masking film is formed by providing the light shieldable release layer on the plastic film base and incorporating the fluorescent material into the light shieldable release layer so that the cutting line formed on the light shieldable release layer generates the fluorescence. Namely, an extremely strong fluorescent color is generated only in the cutting line with the overall coloration of the light shieldable release layer as a background color if the cutting line is formed on the light shieldable release layer contg. the fluorescent material. The visual discrimination of the cutting line is thereby facilitated.</p> |
