Abstract
A recording material comprising a support and a thermosensitive element containing silver behenate, an organic reducing agent therefor in thermal working relationship therewith and a binder, wherein the silver behenate is not associated with mercury and/or lead ions and when the recording material is irradiated with a copper K.alpha..sub.1 X-ray source the ratio, normalized to a quantity of silver in the recording material of 1 g per m.sup.2 thereof, of the sum of the peak heights of the X-ray diffraction lines attributable to silver behenate at Bragg angles, 2.THETA., of 6.01.degree., 7.56.degree., 9.12.degree., 10.66.degree., 12.12.degree. and 13.62.degree. to the sum of the peak heights of the X-ray diffraction lines at Bragg angles, 2.THETA., of 25.60.degree., 35.16.degree. and 43.40.degree. of NIST standard 1976, rhombohedral Al.sub.2 O.sub.3, determined with the same X-ray diffractometer in the same state of adjustment, is greater than 0.85; production processes for particles of substantially light-insensitive organic silver salt comprising silver behenate with these X-ray characteristics in the presence and substantial absence of organic solvent.
