Abstract (en)

A black and white monosheet thermographic recording material having a spectrophotometrically determined maximum absorption for visible light between 570 and 650nm and comprising a support and a thermosensitive element, the thermosensitive element containing a substantially light-insensitive organic silver salt, an organic reducing agent therefor in thermal working relationship therewith and a binder, characterized in that the substantially light-insensitive black and white monosheet thermographic recording material contains at least two colorants with maximum absorption at a wavelength between 450nm and 700nm, none of the at least two colorants is an antihalation dye, and at least one of the at least two colorants is incorporated in the support; and photothermographic and thermographic recording processes therewith.
