    Abstract: An electronic printing method is disclosed which comprises subjecting a radiation sensitive silver halide emulsion layer of a recording element to actinic radiation of at least 10.sup.-4 ergs/cm.sup.2 for up to 100.mu. seconds duration in a pixel-by-pixel mode. The silver halide emulsion layer is comprised of grains predominantly bounded by {100} crystal faces and internally containing three dopants each selected to satisfy a different one of the following class requirements: (i) a metal coordination complex containing a nitrosyl or thionitrosyl ligand in combination with a transition metal chosen from groups 5 to 10 inclusive of the periodic table of elements, (ii) a shallow electron trapping dopant, and (iii) a iridium coordination complex having ligands each of which are more electropositive than a cyano ligand. A gelatino-peptizer for the grains is employed that contains less than 30 micromoles of methionine per gram. The dopants and peptizer in combination increase contrast and provide a highly unexpected increase in high density contrast.

    Abstract: A method for forming a radiation-sensitive high chloride silver halide emulsion is described comprising growing cubical silver halide grains having a central portion accounting for up to 98 percent of total silver of the grains which central portion contains an iridium coordination complex dopant, and chemically sensitizing the surface of the emulsion grains at a pH of at least 5.75. Localized addition of the known in the art reciprocity-controlling iridium dopants to an internal portion of the emulsion grains and chemical finishing of such an emulsion at elevated pH conditions improves reciprocity and latent image stability of the formed high chloride emulsions.
