ABSTRACT:
A transflective optical filter comprises a single transparent or transluscent substrate; a colored slice made up of a plurality of layers, each corresponding to one color out of at least two colors; a light diffusing layer; and an opaque mask on which the marks to be displayed in color are represented by transparent zones, the colored slice and the mask consisting of photographic emulsions. A method for making that filter involves multiple exposures of a same film having a multi-colored "slice" and a monochrome photosensitive layer.
