Abstract
1393433 Magnetic records EASTMAN KODAK CO 8 March 1972 [8 March 1971 28 Jan 1972] 10764/72 Heading G5R [Also in Division G2 and B2] A photographic product e.g. for cinematography comprises at least one support and (i) a layer containing a granular silver image which has been produced by imagewise exposing and developing a photosensitive silver halide emulsion layer and (ii) a magnetic recording layer which is a different layer from the support and silver image layer or is combined with either and which contains magnetisable particles, e.g. gamma ferric oxide CrO 2 or particles of Fe, Ni or Co distributed across at least the silver image area, the concentration and distribution of the particles being such that the RMS value of the granularity of the product is less than four times the RMS value of the granularity of the silver image alone, In photographic materials for making such a product the magnetic layer, when not contained in the support or emulsion may be coated over or under the emulsion layer, or on the opposite side of the support to the emulsion layer. In an alternative embodiment the product is made by placing together one support carrying a developed silver image and another carrying the magnetic layer. The magnetic particles preferably have a grain size distribution of less than 1 micron, and the silver halide in the emulsion preferably has an average grain size of 0À8 microns and a silver coverage of 50 mg/dm<SP>2</SP>.
