<p>A photographic element comprising a paper base with a thickness from 0.025 mm to 0.25 mm, at least one photosensitive silver halide layer, and a layer of microvoided and biaxially oriented polyolefin sheet having a layer thickness of 0.020 mm to 0.050 mm, a density of between 78% and 100% of the solid polymer density located between said paper base and said at least one photosensitive silver halide layer, and wherein the entire photographic element is substantially free from surface distortion or cracking when the photographic element is forced to the shape of a diameter of no less than 8.0 mm. The back of the base may have an oriented polypropylene sheet and the base and the two sheets are laminated to form a support. A copy restrictive pattern of microdots may be placed between the silver halide layer and the microvoided sheet. A laminated support of the microvoided sheet, paper base and a biaxially oriented film is also disclosed.</p> |
