摘要： An optical recording element in which information can be recorded and read directly afterwards by means of laser light, the element comprising, as a recording medium, a dye, which is not capable of being isomerized due to light, dissolved or dispersed in a binder, the binder comprising a thermally cured organic material composed of non-metallic elements only, and having a cross-linked three-dimensional network structure. The thermally cured binder provides improved stability to repeated read.

摘要： A light-sensitive silver halide element for radiographic use with intensifying screens has coated on at least one side of a transparent base at least a spectrally sensitized silver halide emulsion layer and, coated between the base and a silver halide emulsion layer, a hydrophilic colloid layer containing a water-soluble acid dye capable of being decolorized during the photographic processing, said dye having its absorption in a region of the electromagnetic spectrum corresponding to the spectral sensitivity of the silver halide emulsion, associated with a basic polymeric mordant which comprises repeating units of formula: ##STR1## wherein R.sub.1 is hydrogen or a methyl group, A is a --COO-- or --COO--alkylene group, R.sub.2 is hydrogen or a lower alkyl group and X is an anion.The invention allows the use of low coverage weights of silver halide light-sensitive elements and provides x-ray images with a favorable image quality and sensitivity ratio.
