  • Thermally developable imaging materials containing hydroxy-containing polymeric barrier layer
    Patent number: 6420102
    Abstract: Thermographic and photothermographic materials comprise a barrier layer to provide physical protection and to prevent migration of diffusible imaging components and by-products resulting from high temperature imaging and/or development. The barrier layer comprises a film-forming acrylic or methacrylic acid ester or amide polymer(s) that has a molecular weight of at least 8000 g/mole and comprises hydroxy functionality in from about 15 to 100 mole % of the acrylic or methacrylic acid ester or amide recurring units. This barrier layer is capable of retarding diffusion of mobile chemicals such as fatty carboxylic acids, developers, and toners. This barrier layer can also include at least one other film-forming polymer to provide a clear and scratch-resistant surface.
    Type: Grant

  • Thermally developable imaging materials containing polyester polymeric barrier layer
    Patent number: 6352820
    Abstract: Thermographic and photothermographic materials comprise a barrier layer to provide physical protection and to prevent migration of diffusible imaging components and by-products resulting from high temperature development. The barrier layer comprises a film-forming, water-insoluble aromatic polyester that has a molecular weight of at least 10,000 g/mole and is capable of retarding diffusion of mobile chemicals such as fatty acids, developers and toners. This polymer can also be present in admixture with another film-forming polymer to provide a clear and scratch-resistance surface.

  • Thermally developable imaging materials containing surface barrier layer
    Patent number: 6350561
    Abstract: Thermographic and photothermographic materials comprise a surface barrier layer to provide physical protection and to prevent migration of diffusible imaging components and by-products resulting from high temperature development. The barrier layer comprises a film-forming acrylate or methacrylate polymer(s) that has a molecular weight of at least 8000 g/mole and comprises epoxy functionality and is capable of retarding diffusion of mobile chemicals such as fatty acids. This polymer is preferably present in admixture with at least one other film-forming polymer to provide a clear and scratch-resistance surface film.
