Abstract
Abstract This invention is directed to a light sensitive silver halide emulsion comprising a cyclic ether compound having an acid function and to an element containing such emulsion and to a process for using same. The compound comprises, in the cyclic ring, at least two atoms from the group consisting of sulfur and 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.
