Abstract

1312115 Images for episcopic projection ORIZZONTE 2000 PRODUZIONE FILM S R L 8 April 1970 [10 April 1969] 16571/70 Heading G2C An image, such as a photographic film, for episcopic projection, comprises a carrier member supporting, directly or indirectly, a reflective metal layer obtained by vacuum deposition from a vapour, and a transparent image layer secured to the reflective layer. The simplest form is shown in Fig. 1, the carrier member 1 having a reflective metal layer 2 and a transparent imagecarrying layer 3 which may be a photographic film. The reflective layer is deposited by evaporation under vacuum, and finished so that it is specularly reflecting. A layer of magnetic material (4, Fig. 2, not shown) may be provided on the other side of the carrier for sound recording. In the further modification of Fig.4 the magnetic layer 5 is provided between the carrier member 1 and the reflective layer 6. Over the image-carrying layer 7 a further protective transparent layer 8 may be added, and the whole structure may be double-sided, as shown in Fig.4.
