摘要： Thermally developable materials such as thermographic and photothermographic materials include a co-precipitate comprising first and second organic silver salts, the first organic silver salt comprising a silver salt of a nitrogen-containing heterocyclic compound containing an imino group, and the second organic silver salt comprising a silver salt of a mercaptotriazole. The first organic silver salt can be used in the imaging process as a source of reducible silver ions, and the second organic silver salt can be a source of a toning agent. The co-precipitate can be prepared using double-jet precipitation techniques to provide an aqueous dispersion that can be used in imaging formulations.

摘要： Thermally developable materials such as thermographic and photothermographic materials include a novel non-photosensitive source of reducible silver ions that are predominantly provided as rod-shaped particles of silver salt of a nitrogen-containing heterocyclic compound containing an imino group. The rod-shaped particles have an average aspect ratio of at least 3:1 and a width index for particle diameter of 1.25 or less, and provide improved imaging properties. These particles can be prepared using double jet precipitation procedures in which vAg is kept constant at a value of equal to or greater than −50 mV.

The invention provides an improved manufacturing process for the preparation of high bromide silver halide cubical grain emulsion enabling concentrated emulsion batches to be prepared with desired photographic properties. In certain embodiments of the invention, further advantages are enabled in accordance with the discovery that when the exterior portion of high bromide silver halide cubic grains are grown under specific conditions of high molar addition rates, emulsions of enhanced sensitivity, improved contrast and radiographic curve shape may be produced while controlling the minimum fog level.

摘要： A process for preparing a concentrated photographic spectral sensitizing dye-water composition which comprises adding an anionic sensitizing dye to an aqueous medium in the substantial absence of organic solvent, and agitating the combined dye and aqueous medium, wherein the anionic dye forms a liquid-crystalline dye phase in the aqueous medium and the agitation is performed in the presence of a nonionic surfactant having an HLB of less than 12 and an aqueous solubility at 25° C. of greater than 10 ppm, which nonionic surfactant is in the aqueous medium at a level of from 10 to 1000 ppm. In a specific embodiment of the invention, where the viscosity (at 0.1 s−1 shear rate) of the dye-water composition in the absence of the nonionic surfactant would be greater than 100 cp and especially where such viscosity would be greater than 500 cp, the surfactant is preferably present at a level sufficient to substantially reduce air entrainment during agitation of the dye-water composition.
