Preparation of silver halide emulsions |
| abstract |
The preparation of tabular silver bromide iodide emulsions and silver bromide chloride iodide emulsions with an aspect ratio L 2, an iodide content of 1 to 40 mol%, a chloride content of 0 to 20 mol% by the process steps (a) silver halide seed precipitation and (b) at least one further precipitation of silver halide, wherein the seed precipitation or the precipitation of an inner zone of the silver halide grain different from the seed precipitation in an amount of at least one aromatic five- or six-membered heterocyclic compound which is free of -SH-, -SSO 2 H and -SSO 2 R groups from 10 -9 to 10 -4 mol / mol silver is added leads to an improved sensitivity / grain size ratio and to a greater stability of the photographic material containing an emulsion thus produced. |
