  • Reflection preventive light-shielding screen and a process for producing the same
    Patent number: 4506953
    Abstract: A reflection preventive light-shielding screen comprising a transparent plate and a side surface-rough relief of a cured photopolymerized resin composition formed thereon and having a striped pattern or a lattice pattern. The present reflection preventive light-shielding screen can effectively shield extraneous light rays without scattering the light rays emitted from image-indicating devices. Therefore, the present reflection preventive light-shielding screen can be advantageously used for various extraneous light rays-shielding applications. Furthermore, the present reflection preventive light-shielding screen can be produced by an extremely simple process as compared with those of the prior art.
