Photothermographic materials containing high iodide core-shell emulsions |
摘要 |
Aqueous-based thermally developable emulsions and photothermographic imaging materials include photosensitive silver halide core-shell grains that comprise at least 20 mol % iodide based on total silver, an amount of iodide in the core of the grains that can be up to the iodide saturation limit in silver iodobromide, and an amount of iodide in the shell of the grains that is at least 2 mol % less than the amount of iodide present in the core, and further provided that the total amount of silver in the shell is from 10 to 80 mol % of total silver in the grains. These materials provide desired Dmax and reduced image "print out".
