Abstract
The invention relates to an photographic element comprising a transparent polymer sheet, at least one layer of biaxially oriented polyolefin sheet and at least one image layer, wherein said polymer sheet has a stiffness of between 20 and 100 millinewtons said biaxially oriented polyolefin sheet has a spectral transmission between 35% and 90%, said biaxially oriented polyolefin sheet has a reflection density less than 65%.
Claims19
An photographic element comprising a transparent polymer sheet, at least one layer of biaxially oriented polyolefin sheet and at least one image layer, wherein said polymer sheet has a stiffness of between 20 and 100 millinewtons said biaxially oriented polyolefin sheet has a spectral transmission between 35% and 90%, said biaxially oriented polyolefin sheet has a reflection density less than 65%.
A method of imaging comprising providing an photographic element comprising a transparent polymer sheet, at least one layer of biaxially oriented polyolefin sheet and at least one image layer comprising silver halide and a dye forming coupler, wherein said polymer sheet has a stiffness of between 20 and 100 millinewtons, and said biaxially oriented polyolefin sheet has a spectral transmission between 35% and 90%, said biaxially oriented polyolefin sheet has a reflection density less than 65%, exposing said image layer, and developing an image.
A photographic element comprising at least one silver halide imaging layer and a base for said at least one imaging layer wherein said base comprises a transparent polymer sheet and at least one layer of biaxially oriented polyolefin sheet, wherein said polymer sheet has a stiffness of between 20 and 100 millinewtons, said biaxially oriented polyolefin sheet has a spectral transmission between 35% and 90%, said biaxially oriented polyolefin sheet has a reflection density less than 65%.
