Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
75 words
A METHOD OF MAKING A DECORATIVE ARTICLE COMPRISING EVAPORATING A LAYER OF IMAGE FORMING MATERIAL OF AN OXIDE OF BISMUTH FOR A RESULTING LAYER OF BISMUTH TRIOXIDE OF GRAY-BLACK CUBIC CRYSTALLINE FORM ON A SUBSTRATE, COATING THE LAYERED SUBSTRATE WITH A PHOTO SENSITIVE MATERIAL, EXPOSING THE PHOTO SENSITIVE MATERIAL WITH A PICTURE, DEVELOPING THE PICTURE EXPOSED PHOTO SENSITIVE MATERIAL AND ETCHING AWAY THE UNDESIRED BISMUTH TRIOXIDE OF GRAYBLACK CUBIC CRYSTALLINE FORM DEFINED BY THE PICTURE
Claim 2
Independent Claim
75 words
A METHOD OF MAKING A DECORATIVE ARTICLE COMPRISING EVAPORATING A LAYER OF IMAGE FORMING MATERIAL OF AN OXIDE OF BISMUTH FOR A RESULTING LAYER OF BISMUTH TRIOXIDE OF GRAY-BLACK CUBIC CRYSTALLINE FORM ON A SUBSTRATE, COATING THE LAYERED SUBSTRATE WITH A PHOTO SENSITIVE MATERIAL, EXPOSING THE PHOTO SENSITIVE MATERIAL WITH A PICTURE, DEVELOPING THE PICTURE EXPOSED PHOTO SENSITIVE MATERIAL AND ETCHING AWAY THE UNDESIRED BISMUTH TRIOXIDE OF GRAYBLACK CUBIC CRYSTALLINE FORM DEFINED BY THE PICTURE
Claim 3
Dependent Claim
36 words
The method of claim 1 wherein the layering step includes evaporating a layer of image forming material of bismuth trioxide for a resulting layer of bismuth trioxide of gray-black cubic crystalline form on an alumina substrate.
Claim 4
Dependent Claim
40 words
The method of claim 1 wherein the layering step includes evaporating a layer of image forming material of bismuth trioxide for a resulting layer of bismuth trioxide of gray-black cubic crystalline forM on a metal coating on an alumina substrate.
Claim 5
Dependent Claim
24 words
The method of claim 1 wherein the layering step includes evaporating a layer of bismuth trioxide of yellow rhombic crystalline form on the substrate.
Claim 6
Dependent Claim
24 words
The method of claim 1 wherein the layering step includes evaporating a layer of bismuth trioxide of white rhombic crystalline form on the substrate.
Claim 7
Independent Claim
92 words
A method of making a decorative article comprising the steps of: evaporating a layer of image forming material of bismuth trioxide for a resulting layer of bismuth trioxide of gray-black cubic crystalline form for a resulting color contrasting picture on a thin alumina substrate, coating the layered sheet with a photoresist material, preexposure baking of the photoresist, photographically exposing the layered substrate with a picture, developing the exposed photoresist, post exposure baking the photoresist, etching the undesired image forming bismuth trioxide layered on the alumina substrate and post etch baking the assembly.
Claim 8
Independent Claim
92 words
A method of making a decorative article comprising the steps of: evaporating a layer of image forming material of bismuth trioxide for a resulting layer of bismuth trioxide of gray-black cubic crystalline form for a resulting color contrasting picture on a thin alumina substrate, coating the layered sheet with a photoresist material, preexposure baking of the photoresist, photographically exposing the layered substrate with a picture, developing the exposed photoresist, post exposure baking the photoresist, etching the undesired image forming bismuth trioxide layered on the alumina substrate and post etch baking the assembly.
Claim 9
Dependent Claim
27 words
The method of claim 6 wherein the layering step includes applying bismuth trioxide of a gray-black cubic crystalline form on a metal coating on the alumina substrate.
