  • Patent number: 8199176
    Abstract: Thermal transfer donor elements can be used to transfer color images to receiving elements to provide various elements such as color filters. The thermal transfer donor elements include a transparent polymeric substrate and, in order: a propellant layer comprising a gas-producing polymer that is capable of producing a gas upon heating by a thermal layer, and an infrared radiation absorbing compound, a barrier layer, and a thermal dye transfer layer one or more thermally transferable colorants. The barrier layer comprises a hydrophilic material and is transferred with the colorant to provide a transparent overcoat in the final color image. Color transfer can be achieved using laser thermal imaging.
    Type: Grant

  • Patent number: 7226709
    Abstract: A masking film has a unique polymeric binder in the imageable layer that enables the imaged film to be readily solubilized in non-chlorinated developers when it is used to form a relief image in a radiation-sensitive element, such as a UV-sensitive flexographic printing plate precursor. The polymeric binders in the imageable layer are resins that can be dissolved or dispersed in cyclohexane at 10% solids at 23° C. within 24 hours.

  • Patent number: 7172992
    Abstract: The present invention provides a receptor element for use in thermal transfer imaging. The receptor element includes a coating having a polymeric binder and a biguanide bleaching agent. The biguanide bleaching agent is capable of bleaching an infrared-absorbing dye when the biguanide bleaching agent and the infrared-absorbing dye are in contact. A particularly suitable biguanide bleaching agent is 1-(o-tolyl)biguanide. The invention also provides compositions and methods for manufacturing a receptor element. Also provided by the invention is an imaging system for thermal transfer imaging. The imaging system includes a color-bearing element and a bleaching element, wherein the bleaching element includes a coating having a polymeric binder and a biguanide bleaching agent. The invention further provides methods useful in the production of integral proofs.
