Abstract:
A substantially light-insensitive black and white monosheet thermographic recording material having a spectrophotometrically determined maximum absorption for visible light between 570 and 650 nm and comprising a support and a thermosensitive element, said thermosensitive element containing a substantially light-insensitive organic silver salt, an organic reducing agent therefor in thermal working relationship therewith and a binder, wherein said substantially light-insensitive black and white monosheet thermographic recording material contains at least two colorants with maximum absorption at a wavelength between 450 nm and 700 nm; none of said at least two colorants is an antihalation dye; and at least one of said at least two colorants is incorporated in said support, and the other of said at least two colorants is incorporated in said thermosensitive element, in a layer on the other side of said support to said thermosensitive layer or a combination thereof.
