Abstract

1511551 Photographic additive colour silver halide products and transfer processes POLAROID CORP 22 April 1975 [23 April 1974] 16667/75 Heading G2C A photographic product comprises (1) a first photo-sensitive sheet element comprising, in order, a transparent support, a light transmitting screen composed of minute optical elements and a layer containing a photo-sensitive silver halide emulsion and which may be exposed through the screen, (2) a second sheet element, that is superposed or is capable of being superposed on (1) and that is capable of being separated from (1) after processing, comprising a support and on the side of the support adjacent the emulsion when (2) is superposed (1) a silver receptive layer for receiving upon processing a transfer image which is a positive of the negative image or a fogged silver halide layer for receiving by diffusion silver halide developing agent not oxidized by development of exposed silver halide in the emulsion layer, and (3) a rupturable container containing a processing composition capable of developing (1) and positioned to discharge its contents upon rupture between (1) and (2). In a modification the rupturable container (3) is replaced by a sheet impregnated with the processing composition. The emulsion may contain silver halide grains having a mean diameter of 0À7-1À5 microns. At least 90% of the grains may have a diameter within Œ 30% of the mean grain diameter. The emulsion layer may contain 90-200 mg/ft2 silver. The minute optical elements may be lenticules. Preferably the screen is an additive colour screen composed of red, green and blue filter elements, preferably in the form of lines at 550,750 or 1,000 lines/colour/inch. The grains of the silver halide emulsion preferably have a mean diameter of 1/5-1/10 the width of the colour filter elements. The emulsion may be negative or direct-positive. (1) may contain an antihalation layer. (2) may be transparent. The outermost coating of (1) may be a stripping layer. The product may contain a removable opaque layer or the processing composition may contain an opacifying agent to protect the emulsion from fogging during processing. The additive colour negatives produced using the product may be used to provide full colour positive prints or transparencies using conventional subtractive colour printing paper or transparency film.
