Abstract
Photothermographic imaging elements are provided with strippable layers which have electrical conductivity in the range of 60 to 1,500 ohms/square. The elements may be exposed to radiation and then thermally developed by applying a voltage across the strippable layer which becomes resistively heated. After development, the strippable layer may be removed.
Claims8
A photothermographic element comprising a support base having on one surface thereof a photothermographically imageable layer and adhered to the opposite surface of said support base a strippable layer having a resistance of between 60 and 1,500 ohms per square.
