Abstract (en)

According to the present invention there is provided a photothermographic material comprising on a support a photo-addressable thermally developable element containing a substantially light-insensitive organic heavy-metal salt, photosensitive silver halide in catalytic association with said substantially light-insensitive organic heavy-metal salt, a reductor for said substantially light-insensitive organic heavy-metal salt and a binder, said photothermographic material having on the same side of the support as said photo-addressable thermally developable element an outermost layer having two phases at least one of which being a dispersion phase of thermoplastic particles, characterized in that said two phases exhibit different affinities for at least one printing liquid selected from the group consisting of ink and an abhesive fluid for ink.
