摘要：
This invention is directed to a radiation sensitive silver halide emulsion comprising a macroheterocycle having an acid function and to an element containing such emulsion. The macroheterocycle comprises at least two atoms of sulfur or selenium, each of which atoms being separated from one another by a chain of at least two carbon atoms. Such compound acts as a solvent and as a growth modifying agent for silver halide grains. Also described is a process for modifying the growth of silver halide grains.
