ABSTRACT:
A photographic emulsion containing: a photosensitive silver halide; a light-insensitive, reducible silver source; a reducing agent for the light-insensitive, reducible silver source; and a binder consisting essentially of poly(vinyl butyral) having a poly(vinyl alcohol) content of about 17.5 to 21.0 wt. % and at least one solvent selected from the group consisting of: toluene, methyl ethyl ketone, acetone, tetrahydrofuran, and 1,4-dioxane. Additionally, a process for coating a substrate involving applying at least one layer of a molten thermoreversible organogel layer; causing it to gel; and removing residual solvent.
