Abstract
1,187,411. Electron beam recording film. EASTMAN KODAK CO. 17 March, 1967 [20 June, 1966], No. 12691/67. Heading H5R. [Also in Division G2] An electron-sensitive material comprises a support bearing an electrically conductive layer and a layer comprising electron-sensitive direct positive fogged silver halide grains which either (A) comprise a silver halide core containing centres for the deposition of photolytic silver and an outer shell composed of a fogged silver halide; or (B) are silver halide grains fogged such that they satisfy a specified chemical bleach test, and which have absorbed on their surface a compound having one of the formulµ wherein Z 1 and Z 2 complete heterocyclic nuclei, L is a methine group, R 1 and R 2 are alkyl, carboxyalkyl or sulphoalkyl in which the alkyl radical has 1 to 4C, A is an acid anion, m and n are each 0 or 1, p is 0, 1, 2 or 3, X 2 and X 1 are Cl, Br or I, d is 0, 1 or 2 and e is 0 or 1. Blue speed increasing (BSI) compounds which are merocyanine dyes as described in Specification 1,186,718 may be absorbed on the surface of the fogged silver halide grains. The silver halide emulsions may be regular and monodisperse as described in Specification 1,186,711 and 1,186,712. The recording materials may have fluorescent layers. The electrically conductive layer may be coated on one or both sides of the support. The conductive layer may comprise a film-forming binder in which is dispersed colloidal particles of cuprous iodide or silver iodide as a dispersion or as a complexed solute. The support may have electrically conducting particles impregnated therein or may be separated from the electrically conducting layer by a water-permeable layer e.g. vinylidene polymers and copolymers, polyvinyl butyral, polymethyl methacrylate, polyvinyl chloride, cellulose nitrate, and polyesters.
