ABSTRACT:
Thermally developable materials including photothermographic and thermographic materials have an outermost backside layer that includes a combination of a polysiloxane and a smectite clay that has been modified with a quaternary ammonium compound. The resulting outermost backside layers exhibit improved abrasion resistance. The materials can also include conductive layers underneath the outermost backside layer.
