    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： This invention relates to a poly(ethylene terephthalate)-based photographic film base having improved properties with regard to cutting, perforating, and other finishing or phototofinishing operations. The film base comprises a material in which a specified amount of monomeric units derived from 1,4-cyclohexane dimethanol (CHDM), such that the film base has a specified cutting-related property. The level of CHDM in the PET-based polyester material can be adjusted either by physical blending of polyesters containing CHDM monomeric units or by synthetic incorporation of CHDM monomer units into a PET-based polyester backbone.
