  • Photothermographic recording material with in-situ and ex-situ photosensitive silver halide and a substantially light-insensitive organic salt
    Patent number: 6274297
    Abstract: A production process for a photothermographic recording material thermally developable under substantially water-free conditions comprising the steps of: (i) providing a support; (ii) producing one or more aqueous dispersions or solutions containing together a substantially light-insensitive organic silver salt, photosensitive ex-situ silver halide in catalytic association with the substantially light-insensitive organic silver salt, a reducing agent in thermal working relationship with the substantially light-insensitive organic silver salt and a binder; (iii) coating the one or more aqueous dispersions or solutions onto the support to form layers which upon drying become a photo-addressable thermally developable element; and (iv) drying the layers, wherein the photo-addressable thermally developable element contains between 0.2 and 2.

  • Recording material for direct thermal imaging
    Patent number: 5559075
    Abstract: A heat-sensitive recording material suited for use in direct thermal imaging by means of an information-wise energized heating element, which recording material comprises on the same side of a support, called the heat-sensitive side, one or more binder layers containing a substantially light-insensitive metal salt in thermal working relationship with at least one organic reducing agent, characterized in that said recording material also comprises an acid-sensitive leuco dye transformable into dye by means of an acid-reacting compound serving as dye developer that stands in thermal working relationship with said leuco dye.

  • Method for making an imaging element and for obtaining an image therefrom
    Patent number: 5429907
    Abstract: The present invention provides an imaging element comprising a support, a porous layer, a photosensitive layer containing a photopolymerizable composition and optionally a stripping layer characterized in that there is provided a barrier layer between said photosensitive layer and said porous layer said barrier layer being impermeable for the photopolymerizable composition at ambient temperature and capable of increasing its permeability with increasing temperature.
