    摘要: A recording material comprising a support and a thermosensitive element comprising silver palmitate, an organic reducing agent therefor in thermal working relationship therewith and a binder, wherein the silver palmitate 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 of the sum of the peak heights of the X-ray diffraction lines attributable to silver palmitate at Bragg angles, 2.THETA., of 4.01.degree., 6.049.degree., 8.031.degree., 10.06.degree., 12.08.degree. and 14.09.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 on a sample of the recording material and a sample of the NIST standard 1976 cut to fit a sample holder of the X-ray diffractometer, divided by the square root of the quantity of silver in the recording material, expressed in g per m.sup.2, is greater than 3.09 m/g.sup.0.5 ; and a process for producing particles of substantially light-insensitive organic silver salt comprising silver palmitate with these X-ray characteristics in the substantial absence of organic solvent.
