  • Patent number: 5989777
    Abstract: A heat mode element with improved mechanical properties is disclosed comprising a transparent support, a thin metallic recording layer, an adhesive layer, a polymeric resin layer and a top layer comprising a roughening agent in such an amount that the R.sub.a value of said top layer is at least 0.08 .mu.m and the R.sub.z value is at least 0.6 .mu.m. In a preferred embodiment the metallic recording layer is a bismuth layer, and the support has on the other side a backing layer with a low R.sub.a and R.sub.z value.In an alternative embodiment the top layer is absent and the roughening agent is incorporated in the polymeric resin layer itself.Also disclosed is a method for obtaining a heat mode image by the information-wise laser exposure of the disclosed element.

  • Patent number: 5962181
    Abstract: A process is disclosed for the preparation of a heat mode recording element comprising (A) laminating a layer pack (1) containing a temporary support, a release layer, a protective layer, an optional intermediate layer, a subbing layer and a thin metal layer, preferably a bismuth layer, to a layer pack (2) comprising a (thermo)adhesive layer and a permanent support, and (B) peeling off the temporary support and the release layer. In an alternative embodiment, when the protective layer contains a radiation-curable composition, the intermediate layer and the subbing layer can be omitted. A heat mode image is obtained by exposing information-wise a thus defined recording element by means of intense laser radiation, preferably produced by an infra-red laser.

  • Patent number: 5720841
    Abstract: A new type of positive working thermal imaging medium, and a process of forming an image with it is disclosed. This thermal imaging medium comprises a transparent support and (1) a layer comprising a homopolymer or copolymer comprising at least 60 mole % of monomer units containing covalently bound chlorine, (2) a layer containing a homopolymer or copolymer comprising at least 50 mole % of a vinyl acetal monomer unit, (3) an image forming layer, (4) a release layer, and (5) a thermoadhesive layer. After or before exposure to a heat pattern generated directly by a thermal head or indirectly by information-wise exposure to laser radiation a cover sheet is laminated to layer (5). After delamination a positive image is obtained on the original support.

  • Patent number: 5362620
    Abstract: The present invention discloses a photographic material comprising on a support a photosensitive layer containing a mixture of silver halide emulsions at least one of which is spectrally sensitized and at least one of which is not spectrally sensitized characterized in that the surface of the silver halide particles of the silver halide emulsion not being spectrally sensitized is loaded with a stabilizer having a mercapto group or the tautomeric thione group thereof such that the surface covered by one molecule of stabilizer is between 10 .ANG..sup.2 and 70 .ANG..sup.2. The loss of speed due to migration of the spectral sensitizer from the sensitized emulsion to the non sensitized emulsion is reduced and can even be inhibited.
