  • Publication number: 20070111145
    Abstract: Thermally developable materials that comprise a support have a conductive backside layer that has increased conductive efficiency. Conductivity is provided by non-acicular metal antimonate particles that are present in an amount greater than 55 and up to 85 dry weight % at a coverage of from about 0.06 to about 0.5 g/m2, and the ratio of total binder polymers in the backside conductive layer to the non-acicular metal antimonate particles is less than 0.75:1 (dry weights). The level of conductive particles is reduced from previous uses without an unacceptable loss in conductivity. In addition, the dry thickness of the conductive layer is considerably reduced.
    Type: Application
