Abstract
An image-bearing paper is provided which contains a bonding agent that is reticulated by ionizing rays, or bears a coating on at least one surface that contains a bonding agent reticulated by ionizing rays, whereby the bonding agent is predominantly formed of unsaturated substances, and reticulation takes place by means of ionizing rays in or on the paper, which is used as a support material for thermally developable photographic layers, or as an image-receiving material for thermally developed images produced by diffusion of the image-forming substance.
Claims8
A method for making a thermally developable paper photographic support, comprising:
- providing a paper support material suitable for use in photographic systems;
- treating said paper support material with an electron beam hardenable bonding agent composition that contains a compound having carbon-to-carbon unsaturated bonds and a polymerization inhibitor;
- subjecting the paper support material having said bonding agent composition to ionizing election beam radiation in order to thereby harden said bonding agent and provide a carrier having a hardened bonding agent coating;
- and
- coating a thermally developable photographic layer over said hardened bonding agent coating, and said thermally developable photographic layer is a thermographic dry system including an organic silver salt and an organic reduction agent;
- whereby the thermally developable paper photographic support made by this method is resistant to fogging by the polymerization inhibitor of the electron beam hardenable bonding agent composition.
A method for making and developing a thermally developable paper photographic support, comprising:
- providing a paper support material suitable for use in photographic systems;
- treating said paper support material with an electron beam hardenable bonding agent composition that contains a compound having carbon-to-carbon unsaturated bonds and a polymerization inhibitor in sufficient quantity to prevent polymerization of the unsaturated compound during storage;
- subjecting the paper support material having said bonding agent composition to ionizing electron beam radiation in order to thereby harden said bonding agent and provide a carrier having a hardened bonding agent coating;
- coating a thermally developable photographic layer over said hardened bonding agent coating to form a coated paper photographic support, and said thermally developable photographic layer is a thermographic dry system including an organic silver salt and an organic reduction agent;
- and
- thermally developing said coated paper photographic support in the absence of fogging of the electron beam hardenable bonding agent composition.
