Abstract

PURPOSE:To obtain the title film which has the performance such as the high anti- reflection property, etc., and reduces the abrasion of a cutting knife by forming a light shielding releasing layer composed of a releasing layer forming org. high polymer compd., a light shielding dyestuff or pigment and an org. filling agent on a supporting body. CONSTITUTION:The title film is obtd. by forming a light shielding releasing layer composed of the releasing layer forming org. high polymer compd., the light shielding dyestuff or pigment and the org. filling agent, on the supporting body. A synthetic resin film composed of polyvinylidene chloride, etc., is used for the supporting body, and a combination of a copolymer of vinyl chloride-vinylidene chloride and a nitrile rubber (acrylonitrile-butadiene rubber) is preferably used for said org. high polymer compd. And, an oil soluble dyestuff which is soluble to an org. solvent and capable of shielding a light having a wavelength of 300-550nm is used for the shading dyestuff or pigment. A polystyrene beads is preferably used for the org. filling agent. The title film is formed by uniformly applying the composition composed of components as mentioned above on the one side of the supporting body by means of a prescribed method. Thus, the title film which has the less abrasion of the cutter knife and the excellent stability against a coating solution etc., is obtd.
