Abstract:
The photographic element comprising a base, at least one color forming layer comprising at least one silver halide emulsion layer, and one dye forming coupler, wherein said base comprises a transparent polymer sheet having laminated to its upper surface a microvoided biaxially oriented polyolefin sheet and wherein said biaxially oriented polyolefin sheet has an upper nonglossy surface that has a roughness of between 0.3 and 2.0 &mgr;m, wherein the biaxially oriented polyolefin sheet upper surface roughness has a spatial frequency of between 200 and 500 cycles/mm, and wherein said upper surface roughness is provided by an integral layer of said biaxially oriented polyolefin sheet that is provided with an additive which provides roughness during orientation of said sheet, and wherein said microvoided biaxially oriented polyolefin sheet has a spectral transmission of less than 15%.
