  • Patent number: 6235459
    Abstract: An imaging support element comprising a polymeric film support and a thermally stable single subbing layer is made by forming a coating over the polymeric film support, the coating having a surface including amine reactive groups in a density of at least 1010 per cm2 and then heat treating the polymeric film support with the coating thereon at a temperature in the range of from about 50° C. below the glass transition temperature (Tg) of the polymeric support up to the glass transition temperature (Tg) of the polymeric support. The polymeric film support is nitrogen plasma treated. The layer is preferably formed by coating a monomer solution on the nitrogen plasma treated polymer support wherein the coated monomer has at least two vinyl sulfone groups which provide the amine reactive groups. Alternatively, the layer may be formed by applying to the polymeric support web a coating including at least one non-amine reactive comonomer and at least one comonomer having amine reactive side groups.

  • Patent number: 6228571
    Abstract: A photothermographic material has on one surface of a support at least one photosensitive layer containing a photosensitive silver halide, an organic silver salt, and a reducing agent. A non-photosensitive layer or back layer is formed on the back surface of the support by applying a coating solution of a binder containing at least 50% by weight of a polymer latex dispersed in a solvent containing at least 30% by weight of water and drying the coating. The polymer latex is of a polymer having an equilibrium moisture content of less than 2% by weight at 25° C. and RH 60%. The back layer can be coated at a low cost without a need for a harmful organic solvent. Upon storage in a humid atmosphere, sheets of the material are minimized in fog and free of sticking.
