Abstract

PURPOSE:To obtain a shutter blade for a camera while improving workability and providing the sufficient property of cutting off light by laminating metallic foil on the surface of a plastic sheet and by covering its surface with a lubricant black organic film. CONSTITUTION:On the surface of a plastic sheet or film of polyester, etc., metallic foil of nickel, chronium, etc., is laminated in a thermal press-contacting method through an adhesive of epoxy, etc. Then, this surface is coated with black organic paint which contains a dispersed lubricity providing agent, thus forming a reflection preventing film. This material is used to form blade of a focal plane shutter. Those shutter blade are used effectively for, specially, an electromagnetically driven shutter.
