    摘要: A method of forming an optical compensation film includes coating one or more first layers and one or more second layers onto a carrier substrate, and stretching the first layers and second layers simultaneously. The one or more first layers include a polymer having an out-of-plane birefringence (Δnth) not more negative than −0.005 and not more positive than +0.005, and the one or more second layers include a polymer having an out-of-plane birefringence more negative than −0.005 or more positive than +0.005. The overall in-plane retardation (Rin) of the optical compensation film is greater than 20 nm and the out-of-plane retardation (Rth) of the optical compensation film is more negative than −20 nm or more positive than +20 nm.

    摘要: The invention relates to an imaging element comprising an imaging layer and a support, wherein the support comprises a base material having thereon at least two polyolefin layers, wherein the uppermost layer of the at least two polyolefin layers comprises a mixture of optical brighteners comprising a Compound A having the following formula: a Compound B having the following formula: and a Compound C having the following formula: wherein the layers below the uppermost layer of the at least two polyolefin layers comprise migratory optical brightener; and wherein the imaging layer is on the same side of the base material as the at least two polyolefin layers. The inventive support unexpectedly minimizes exudation of the brightener at the polyolefin surface and provides excellent absorption/emission characteristics, brightening power and heat to meet the critical requirements of the photographic field.
