A method for producing a relief pattern comprising forming one of (i) a silver image, (ii) a silver halide image, or (iii) an image obtained by toning and/or intensifying the silver image or silver halide image, in the emulsion layer of a photographic light-sensitive material which comprises a support having thereon at least one silver halide emulsion layer, either directly or on at least one subbing layer on the support, by image-wise exposing to light and developing, heating the photographic material to decompose the binder of the emulsion layer, and then ion-etching the photographic material to form a relief pattern of the support corresponding to the above-described image.
