  • Antistatic properties for thermally developable materials
    Patent number: 7144689
    Abstract: The use of metal antimonates at high metal antimonate to binder ratios in buried backside conductive layers of thermographic and photothermographic materials allows the use of thin backside overcoat layers. The combination provides antistatic constructions having excellent antistatic properties that show less change in resistivity with changes in humidity. The thin backside overcoat layer serves to protect the buried antistatic layer.
    Type: Grant

  • Thermally developable materials with improved conductive layer
    Patent number: 7141361
    Abstract: Buried backside conductive layers with increased conductive efficiency can be provided for thermally developable materials using a specific organic solvent mixture to coat a protective overcoat directly disposed over the conductive layer. This organic solvent mixture comprises an alcohol in which one or more film-forming polymers used in the formulation are soluble at room temperature. The alcohol is used in an amount of more than 10 and up to 90 weight % of the organic solvent mixture.

  • Thermally developable materials with narrow disperse amorphous silica
    Patent number: 7105284
    Abstract: Thermally developable materials including photothermographic and thermographic materials having an outermost backside layer that includes amorphous silica particles having a narrow particle size distribution. The narrower particle size distribution provides reduced haze and increased surface roughness that reduces blocking and machine feeding at comparable weight percent. The materials can also include conductive layers underneath the outermost backside layer.

  • Thermally developable materials having improved backside conductive layers
    Patent number: 7022467
    Abstract: Backside conductive layers with increased conductive efficiency can be provided for thermally developable materials by providing a buried conductive coating containing a lower molecular weight polyvinyl acetal binder (that is, a molecular weight of at least 8,000 and less than 30,000).

  • Thermally developable materials with improved backside layers
    Patent number: 7018787
    Abstract: Thermally developable materials such as photothermographic and thermographic materials have a backside conductive layer with increased conductive efficiency. This backside conductive layer is a buried conductive coating and is overcoated with a layer that contains a smectite clay modified with a quaternary ammonium compound.
