Abstract:
A substantially light-insensitive thermographic recording material comprising a support and a thermosensitive element, said thermosensitive element containing silver behenate including phase I silver behenate having an X-ray diffraction spectrum upon irradiation with a copper K&agr;1 X-ray source with Bragg angles 2&THgr; of 4.53%, 5.96-6.05Â°, 7.46-7.56Â°, 8.90-9.12Â°, 10.45-10.66Â°, 12.02-12.12Â°, 13.53-13.62Â°, a reducing agent therefor in thermal working relationship therewith and a binder, wherein said 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&agr;1 X-ray source with Bragg angles 2&THgr; of 5.34-5.78Â°, 6.12-6.41Â°, 7.68-7.79Â°, 830-8.59Â°, 9.36-9.84Â°, 10.6-10.96Â°, which is stable at 25Â° C., with respect to said phase I silver behenate present in said thermographic recording material before said thermal development.
