ABSTRACT:
A (photo)thermographic recording material comprising a (photo-addressable) thermosensitive element on one side of a water resistant support and an outermost backside layer on the other side of the water resistant support, the (photo-addressable) thermosensitive element comprising a substantially light-insensitive organic silver salt, an organic reducing agent for the substantially light-insensitive organic silver salt in thermal working relationship therewith(, photosensitive silver halide in catalytic association with the substantially light insensitive organic silver salt) and a binder and the outermost backside layer comprising polymeric beads, characterized in that an outermost layer on the side of the water resistant support with the (photo-addressable) thermosensitive element does not contain a fluorine-containing polymeric surfactant and the static frictional coefficient between the outermost layer on the side of the water resistant support with the (photo-addressable) thermosensitive element and the outermost backside layer is .ltoreq.0.24 and/or the outermost backside layer of the (photo)thermographic recording material has an R.sub.z determined according to DIN 4768/1 of >1.75 .mu.m; and a (photo)thermographic recording process therefor.
