Claims59
A photographic element comprising at least one photosensitive silver halide emulsion layer and a metallic layer between said at least one photosensitive silver halide emulsion layer and a support, wherein there is a transparent polymer layer between said metallic layer and said at least one silver halide emulsion layer and wherein said transparent polymer layer is between 10 and 250 μm thick, said metallic layer comprises a metal vacuum deposited onto a polymer carrier sheet, and wherein said polymer carrier sheet comprises a biaxially oriented polymer sheet.
A photographic element comprising at least one photosensitive silver halide emulsion layer and a metallic layer between said at least one photosensitive silver halide emulsion layer and a support, wherein there is a transparent polymer layer between said metallic layer and said at least one silver halide emulsion layer, wherein said metallic layer has a reflectance greater than 85% of the visible spectrum, and wherein said metallic layer comprises at least one material selected from the group consisting of aluminum, nickel, gold, steel, zinc, copper, titanium, and metallic alloys.
A photographic element comprising at least one photosensitive silver halide emulsion layer and a front side metallic layer between said at least one photosensitive silver halide emulsion layer and a support, wherein there is a transparent polymer layer between said metallic layer and said at least one silver halide emulsion layer, wherein said metallic layer has a reflectance greater than 85% of the visible spectrum, and wherein said metallic layer comprises at least one material selected from the group consisting of aluminum, nickel, gold, steel, zinc, copper, titanium, and metallic alloys and wherein said element further comprises a metallic layer on the backside of said support.
A photographic element comprising at least one photosensitive silver halide emulsion layer and a metallic layer between said at least one photosensitive silver halide emulsion layer and a support and wherein there is a transparent polymer layer between said metallic layer and said at least one silver halide emulsion layer, wherein said metallic layer has a reflectance greater than 85% of the visible spectrum, and wherein said metallic layer comprises at least one material selected from the group consisting of aluminum, nickel, gold, steel, zinc, copper, titanium, and metallic alloys wherein said polymer carrier sheet comprises a biaxially oriented polymer sheet.
A photographic element comprising at least one photosensitive silver halide emulsion layer and a metallic layer between said at least one photosensitive silver halide emulsion layer and a support, wherein there is a transparent polymer layer between said metallic layer and said at least one silver halide emulsion layer and wherein said transparent polymer layer is between 10 and 250 μm thick, said metallic layer is reflective, said metallic layer comprises at least one material selected from the group consisting of aluminum, nickel, gold, steel, zinc, copper titanium, and metallic alloys and wherein said metallic layer has a reflectance of greater than 85% of the visible spectrum.
