Abstract
This invention relates to a photographic element comprising a base paper, and biaxially oriented sheets on each side of said base paper wherein said biaxially oriented sheets and said base paper have the strongest direction of each web within 3 degrees of the machine direction or cross direction, and wherein each web has a machine direction to cross machine direction stiffness ratio of greater than 1.5 or less than 0.7.
Claims23
An imaging element base comprising at least two webs wherein the strongest direction of each web is within 3 degrees of machine direction or cross direction, and wherein each web has a machine direction to cross machine direction stiffness ratio of greater than 1.5 or less than 0.7 wherein said at least two webs comprise an upper and lower biaxially oriented polymer sheet and a middle web selected from the group consisting of paper, cloth, woven polymer fibers, and microvoided polyethylene terephthalate.
A photographic element comprising at least silver halide photosensitive containing layer and an imaging element base comprising at least two webs wherein the strongest direction of each web is within 3 degrees of machine direction or cross direction, and wherein each web has a machine direction to cross machine direction stiffness ratio of greater than 1.5 or less than 0.7 wherein said at least two webs comprise an upper and lower biaxially oriented polymer sheet and a middle web selected from the group consisting of paper, cloth, woven polymer fibers, and microvoided polyethylene terephthalate.
