Process for the manufacture of a relief element.

摘要

A process for the manufacture of a relief element suited for use in liquid crystal display panels to control the gap-width of the liquid crystal layer, which process comprises the steps of : (I) pattern-wise photo-exposing a photographic silver halide emulsion material comprising on a support a single gelatin containing silver halide emulsion layer to form a latent pattern of exposed silver halide, (II) treating the exposed silver halide emulsion layer with an aqueous solution containing a developing agent and a colourless coupling agent capable of forming with oxidized developing agent a diffusion resistant colourless reaction product increasing the thickness of said emulsion layer in the exposed portions. The use of said process in the production of a mosaic type multi-colour filter element as illustrated in Fig. 2.
