ABSTRACT:
A novel process for the preparation, for example of gelatino silver chloride and silver bromochloride grains with modified tabular crystal habit is described. These grains are prepared using standard single jet (SJ) or balanced double jet (BDJ) techniques, said preparation occurring in the presence of a modifying amount of an aminoazapyridine as defined and a suitable binder to form well-developed, sensitive tabular elements with a median grain volume in the range of 0.005 to 0.50 .mu.m.sup.3.
