  • Patent number: 7214464
    Abstract: The present invention is directed to a method of forming a positive image in a photothermographic assembly comprising a photothermographic material and an intensifying means for converting ionizing radiation, wherein the assembly has been imagewise exposed to ionizing radiation to form a latent image in the photothermographic material. The photothermographic material has at least one imaging layer comprising a potentially negative-working emulsion, wherein thermal development of unexposed silver salts in exposed areas relative to unexposed areas is inhibiting when thermally developing the imagewise exposed assembly, thereby producing a positive image. The present invention is also directed to a photothermographic assembly that can be used in the present process in which a positive image characterized by high speed and discrimination is formed when exposed and thermally heated above 150° C.

  • Patent number: 7211294
    Abstract: The invention provides a method of making a material. The method comprises the step of coating a support with a solution comprising a hydrophilic polymer and a blowing agent. Either prior to or after the step of coating the support, the solution is interacted with in some way e.g. heated, to cause the blowing agent to generate gas bubbles within the solution, causing foaming of the hydrophilic polymer.

  • Patent number: 7198889
    Abstract: The present invention is directed to a method of forming a positive image in a photothermographic element comprising a potentially negative-working emulsion wherein fog density development is imagewise inhibited in exposed areas of the image upon thermal development, the element further comprising a developer or precursor thereof and an oxidized developer scavenging agent to accelerate development by removing oxidized developer as it is formed during the thermal development step. In one embodiment of the invention, in which a density-inhibiting agent is released during thermal development that inhibits the thermal development of unexposed silver salts in the exposed areas relative to the unexposed areas, the method comprises imagewise exposing the film with a non-solarizing amount of radiation/energy to form a latent image and thermally developing the latent image in a single development step to produce a positive image in the element.

  • Patent number: 7189299
    Abstract: Processes for making a pragmatic label, a receiver sheet for making such a pragmatic label, and intermediates thereof are described. The receiver sheet comprises a pragmatic pre-label sheet, a lower strippable carrier, a pressure-sensitive adhesive layer between said lower strippable carrier and the pragmatic pre-label sheet. The pragmatic pre-label sheet is made by coextruding a first melt for a polymeric image-receiving layer with one or more other melts for forming a single-layer or multiple-layer pragmatic polymer sheet, wherein said other melts includes a second melt comprising an orientable thermoplastic polymeric material for forming a microvoided layer, said coextruded melts forming a multilayer composite film that is subsequently subjected to stretching. The pragmatic labels and receiver sheets of the present invention can advantageously be made without the use of solvent coating.
