Process of preparing a tabular grain silver bromoiodide emulsion and emulsions produced thereby. |
摘要 |
<p>A process is disclosed for the preparation of a tabular grain silver bromoiodide emulsion in which silver bromoiodide laminae are formed on the major faces of the tabular grains. The sensitivity of the emulsion as a function of pressure applied is rendered more nearly constant by forming the silver bromoiodide laminae on the major faces of the tabular grains. The silver bromoiodide laminae are formed on the major faces of the tabular grains with an iodide content higher than that of the host emulsion, and thereafter, within the pAg and temperature boundaries defined by Curve A in Figure 1, bromide is deposited as a silver salt with the addition of iodide being limited or absent.</p> |
