Surface formed lenses on voided polymer light diffuser

A process for making polyester film base material comprising more than 65 mol % of 1,4-cyclohexanedimethanol (CHDM) of the total glycol component in the polyester material. The film base is prepared by sequentially carrying out the following steps: (a) casting a molten polyester resin in a machine direction onto a casting surface to form a continuous sheet, (b) drafting the sheet by stretching in the machine direction at a stretch ratio of from 2 to 4, and at a temperature ranging from 70&deg; C. to 130&deg; C., (c) tentering the sheet in the transverse direction by stretching at a stretch ratio of from 2 to 4, and at a temperature ranging from 70&deg; C. to 130&deg; C. to obtain a biaxially oriented film, (d) heat-setting the oriented film at an actual temperature of from 160&deg; C. to 200&deg; C., and (e) cooling the heat-set film without substantial detentering to obtain a biaxially oriented, heat-set polyester-based film having a cutting index of 1 to 1.5 and a tensile toughness ranging from 15 to 55 MPa. The invention is also directed towards a silver halide light sensitive photographic element comprising the PET-based film base made by the present process. The photographic film base of the invention exhibits excellent dimensional stability, optical clarity and mechanical strength while also possessing a crystalline morphology that enables finishing by cutting, chopping or perforating techniques at reduced cutting index without requiring a detentering step after heat-setting.

Process for making polyester photographic film base and photographic element comprising said base

This invention relates to a PET-based photographic multilayer film base having improved properties with regard to cutting, stiffness and post-process curl. In particular, the polyester film base comprises a biaxially-stretched multilayer film structure, in which layers a specified amount of monomeric units derived from 1,4-cyclohexanedimethanol (CHDM), sulfonic-acid-substituted aromatic dicarboxylic acid and poly(alkylene glycol) is present.

Multilayer photographic film and an imaging element made of said base

This invention relates to a poly(ethylene terephthalate) photographic multilayer film base having improved properties with regard to cutting, stiffness and curl property. The multilayer film base comprises a multilayer structure, in which a tie layer comprises a PET-based polyester material having a specified amount of monomeric units derived from 1,4-cyclohexanedimethanol (CHDM), such that the support layers of the multilayer film base does not delaminate. This PET-based polyester material can be obtained either by the addition/blending of polyester polymers containing CHDM monomeric units to PET material and/or the incorporation of CHDM monomer units into a PET-polymer backbone at appropriate levels.
