Abstract (en)
A substantially light-insensitive thermographic recording material comprising a support and a thermosensitive element, the thermosensitive element containing silver behenate including phase I silver behenate having an X-ray diffraction spectrum upon irradiation with a copper K alpha 1 X-ray source with Bragg angles 2 THETA of 4.53 DEG , 5.96-6.05 DEG , 7.46-7.56 DEG , 8.90-9.12 DEG , 10.45-10.66 DEG , 12.02-12.12 DEG , 13.53-13.62 DEG , a reducing agent therefor in thermal working relationship therewith and a binder, wherein the thermographic recording material is capable upon thermal development of containing 1% of phase II silver behenate, having an X-ray diffraction spectrum upon irradiation with a copper K alpha 1 X-ray source with Bragg angles 2 THETA of 5.34-5.78 DEG , 6.12-6.41 DEG ,7.68-7.79 DEG , 8.30-8.59 DEG , 9.36-9.84 DEG , 10.6-10.96 DEG , and/or phase III silver behenate phase, having an X-ray diffraction spectrum upon irradiation with a copper K alpha 1 X-ray source with Bragg angles 2 THETA of 4.76-4.81 DEG , 5.9-6.3 DEG , 6.76-7.35 DEG , 8.27-8.44 DEG and 9.06-9.43 DEG , which is stable at 25 DEG C, with respect to the quantity of the phase I silver behenate in the thermographic recording material before said thermal development; a recording process therefor; and use of the above-defined phase II silver behenate stabilized at 25 DEG C and/or the above-defined phase III silver behenate stabilized at 25 DEG C as a tone modifier in thermographic recording materials.
