ABSTRACT:
A process is disclosed for increasing the sensitivity of negative-forming radiation sensitive silver halide layers by treating such silver halide layers with hydrogen. The layers thus treated manifest a reduced or substantial absence of reciprocity law failure as well as increased sensitivity to electromagnetic radiation. The products so treated can contain spectral and chemical sensitizers and/or color forming dye-couplers and/or other suitable addenda conventionally employed with photosensitive elements. The products can also exhibit the ability to increase still further in photosensitivity even after imagewise exposure thereof upon prolonged storage of the exposed products under ambient conditions before they are developed.
