Abstract
Abstract 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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
113 words
A method for producing a relief pattern comprising in sequence forming one of (i) a silver image, (ii) a silver halide image, and (iii) an image obtained by toning and/or intensifying said silver 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 exposure to light and developing; heating said photographic material at a temperature greater than 150° C to thermally decompose the binder of said emulsion layer; and then ion-etching the photographic material to form a relief pattern in the support corresponding to said image.
Claim 2
Independent Claim
113 words
A method for producing a relief pattern comprising in sequence forming one of (i) a silver image, (ii) a silver halide image, and (iii) an image obtained by toning and/or intensifying said silver 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 exposure to light and developing; heating said photographic material at a temperature greater than 150° C to thermally decompose the binder of said emulsion layer; and then ion-etching the photographic material to form a relief pattern in the support corresponding to said image.
Claim 3
Dependent Claim
56 words
The method of claim 1, wherein said support is a plate or film of glass, a ceramic, a cermet, silica, sapphire, a metal, a semi-metal, a high melting point polymeric substance, a porcelain enamel, a metal coated with a ceramic, a metal having a metal oxide layer thereof, or a combination of two or more thereof.
Claim 4
Dependent Claim
67 words
The method of claim 2, wherein said glass is silica glass, soda lime glass, potash glass, borosilicate glass or barium glass, said ceramic is an alumina ceramic, said semi-metal is silicon, germanium, Ga-As, Ga-P, or In-P, and said metal is nickel, copper, cobalt, chromium, aluminum, titanium, gold, platinum, palladium, rhodium, iridium, a nickel-iron alloy, a nickel-chromium alloy, a nickel-cobalt alloy, an aluminum-iron alloy, or a chromium-iron alloy.
Claim 5
Dependent Claim
28 words
The method of claim 1, wherein said silver halide emulsion layer comprises silver chloride, silver bromide, silver iodide, silver chlorobromide, silver bromoiodide, silver chlorobromoiodide or a mixture thereof.
Claim 6
Dependent Claim
67 words
The method of claim 4, wherein said silver halide emulsion comprises about 90 mole % or more silver bromide and not more than about 5 mole % silver iodide and the mean grain size of the silver halide grains is not more than about 0.1 micron and wherein the weight ratio of the silver halide to the binder of the emulsion is about 1:4 to about 6:1.
Claim 7
Dependent Claim
36 words
The method of claim 4, wherein said silver halide emulsion comprises about 50 mole % or more silver chloride and the mean grain size of the silver halide grains is not more than about 1 micron.
Claim 8
Dependent Claim
53 words
The method of claim 1, wherein said toning and/or intensification of the silver image is conducted using an aqueous solution of at least one compound containing one element selected from the group consisting of mercury, copper, lead, uranium, selenium, sulfur, iron, nickel, cobalt, vanadium, titanium, chromium, cadmium, gold, platinum, palladium, iridium and rhodium.
Claim 9
Dependent Claim
13 words
The method of claim 1, wherein said heating is at above 300° C.
Claim 10
Dependent Claim
11 words
The method of claim 1, wherein said ion-etching is sputter etching.
Claim 11
Dependent Claim
11 words
The method of claim 1, wherein said image has continuous gradation.
Claim 12
Dependent Claim
19 words
The method of claim 1, wherein said ion-etching is carried out until the decomposed emulsion layer is completely removed.
Claim 13
Dependent Claim
10 words
The method of claim 1, wherein said support is transparent.
