ABSTRACT:
A (photo) thermographic recording material comprising a substantially colourless support and a (photo-addressable) thermosensitive element containing 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 is catalytic association with the substantially light-insensitive organic silver salt) and a binder, characterized in that a blue pigment or dye having a maximum absorption wavelength of from 550 to 700 nm is present in the thermosensitive element and/or any other layer on either side of the support which provides a background for viewing in transmission images produced with the (photo) thermographic recording material; and a (photo) thermographic recording process therefor.
