Method for the production of a multicolour filter array wherein individual colour pixels are delineated by a light absorbing contour pattern, which method comprises the steps of : (1) providing a photosensitive dye receptor material being a photographic silver halide emulsion material incorporating at least one waterpermeable silver halide emulsion layer on a support and containing optionally a mordanting agent suited for fixing dyes in said silver halide emulsion layer and/or in another layer in waterpermeable relationship therewith, (2) depositing pixelwise different dyes or dye precursors compounds wherefrom dyes can be formed by chemical reaction onto said photosensitive dye receptor material, (3) photo-exposing said at least one silver halide emulsion layer of said dye receptor material to a light pattern resulting in a latent image in the form of a contour line pattern delineating the individual colour pixels obtained in said dye receptor material, and (4) developing said latent image to form in said dye receptor material an image representing a light-absorbing contour line pattern delineating the individual colour pixels.
