Abstract
Abstract A photographic support comprising a substrate having thereon a metal film layer having mirror reflective surface or secondary diffuse-reflective surface and an adhesive layer on the metal film layer, wherein the adhesive layer contains a copolymer composition of a diolefin and at least one other ethylenically unsaturated polymerizable monomer, or a silane coupling agent represented by formula (2-I) or (2-II): <IMAGE> (2-I) <IMAGE> (2-II) wherein Y represents an organic functional group, R represents an alkylene group having 1 to 5 carbon atoms, R' represents an alkoxy group having 1 to 4 carbon atoms, and n represents 2 or 3.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
104 words
A photographic element comprising a support having provided thereon at least one light-sensitive silver halide emulsion layer, wherein said support comprises a substrate having thereon a metal film layer having a secondary diffuse-reflective surface and an adhesive layer on said metal film layer, wherein said adhesive layer consists of a silane coupling agent represented by formula (2-I) or (2-II): ##STR63## wherein Y represents an organic functional group, R represents an alkylene group having 1 to 5 carbon atoms, R' represents an alkoxy group having 1 to 4 carbon atoms, and n represents 2 or 3, and has a thickness of 0.01 to 5 μm.
Claim 2
Dependent Claim
104 words
A photographic element comprising a support having provided thereon at least one light-sensitive silver halide emulsion layer, wherein said support comprises a substrate having thereon a metal film layer having a secondary diffuse-reflective surface and an adhesive layer on said metal film layer, wherein said adhesive layer consists of a silane coupling agent represented by formula (2-I) or (2-II): ##STR63## wherein Y represents an organic functional group, R represents an alkylene group having 1 to 5 carbon atoms, R' represents an alkoxy group having 1 to 4 carbon atoms, and n represents 2 or 3, and has a thickness of 0.01 to 5 μm.
