(under subclass 564) Processes including the step of preparing a dispersion of a solid radiation sensitive silver compound in a liquid medium. This includes, e.g., the reaction of silver nitrate with halogen ion in a medium to produce an AgX dispersion, or the dispersion of preformed AgX in a liquid.
(1) Note. Mere addition of an additive to an existing AgX dispersion is excluded and placed below on some other feature, such as the composition made.
