Abstract
Photographic systems with a separate photographic change carriers capture in depth and on a surface of emulsion microcrystals (`core-shell') have a great importance for photographic technology (direct positive, infra-red films and etc.) and also for scientific investigation. We have precipitated AgBr(I) core microcrystals (with AgI content from 0 up to 6 mol.%), which then were subjected to chemical sensitization of various types (reduction, S, S+Au, Au). A sensitometric study of the covered by shell of various thickness and halide composition initial microcrystals has been carried out. An effect of the loss of internal sensitivity is found. A nature of this effect is proposed and ways of its elimination are offered.
