PURPOSE:To permit impartation of good light shieldability, film formability, aging resistance, easy releasability and restickability by forming a restickable release layer consisting of an ethylene/vinyl acetate copolymer and intermediate layer consisting of PE by co-extrusion on a base film and further, coating and forming a specific light shieldable layer thereon. CONSTITUTION:The base film 10 is a PE terephthalate film. The restickable layer 21 is formed as a restickable light shieldable release layer 20 on the base film 10 by the co-extrusion of the restickable layer 21 consisting of ethylene/vinyl acetate copolymer and the intermediate layer 22 consisting of PE. The light shieldable layer 23 consisting of a mixture composed of a rubber-like material, material having compatibility with said material and light shieldable dye or pigment is further coated and formed thereon. The light shieldability, film formability, aging resistance, easy releasability and restickability are thereby imparted to the masking film. |
