Photographic Silver Halide Emulsions, Process For Preparing The Same And Their Use In Color Reversal Films And Color Print Films Abstract Of Disclosure Photographic emulsions including high-iodide silver iodo-bromide grains dispersed in gelatin showed high-sensitivity cha- racteristics when such grains have a composite structure including three iodo-bromide phases having different iodide contents. The con- tents vary from external levels of percent iodide lower than the no- minal iodide content to internal percentages of iodide higher than the nominal content. Such emulsions are particularly good in obtaining a high-sensitivity color reversal film or included in the high sen- sitivity hemilayer of a color print negative film.
