ルムを開示するものである。 In other words, the present invention involves coating the surface of a transparent or translucent synthetic resin film colored orange, yellow, or red with an organic solvent-soluble resin layer containing a small amount of fine particle matting agent to form a transparent layer. This invention discloses a light-shielding film in which a translucent or opaque metal thin film is deposited on the back surface.

貼り合せてよもい。 1 is a transparent or translucent synthetic resin film colored orange, yellow or red; 2 is a transparent resin layer coated on the surface of the synthetic resin film 1; this resin layer is disclosed in Japanese Patent Publication No. 51-34734 Publications and Utility Application No. 180335 (Sho 58-
88241), organic solvents (e.g. alcohols, ketones, chlorinated One type or a mixture of two or more types of hydrocarbons, etc.) Soluble polyolefin-based, acrylic acid-based, polyvinyl chloride-based resins, etc. are used. 3 is a translucent or opaque metal thin film (for example, aluminum thin film) deposited on the back surface of the film 1. In addition, as shown by the imaginary line, in order to strengthen the stiffness of the film 1 and prevent the oxidation of the deposited metal 3, a preferably white synthetic resin film 5 may be bonded to the metal thin film 3.

付かれずに盗用されることは不可能になる。 Since the present invention has the above-described structure, characters, figures, etc. can be easily written on the resin layer 2 on the surface of the synthetic resin film 1 by handwriting, printing, copying, etc., and the written characters, Even if the figure 4 is electronically copied or photographed, the light rays pass through the synthetic resin film layer 1 colored orange, yellow or red from the resin layer 2, are reflected by the metal vapor deposited film 3, and are reflected again on the synthetic resin film layer 1 and the synthetic resin film layer 1. Since it is reflected through the resin layer 2, the copy paper or negative becomes entirely black, and the characters, figures, etc. 4 cannot be seen at all, making it impossible for people to steal it without being noticed.
