Abstract
A composite, lightsafe masking film is disclosed which comprises a substrate formed of a plastic material, and a lightsafe layer peelably provided over the surface of said substrate. A fluorescent substance is incorporated into the lightsafe layer, or a fluorescent substance-containing layer is provided on the surface of the lightsafe layer or between the lightsafe layer and the substrate, so that a cutting line formed on the lightsafe layer fluoresces under illuminated conditions to form a legible pattern.
