摘要： 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° C. to 130° 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° C. to 130° C. to obtain a biaxially oriented film, (d) heat-setting the oriented film at an actual temperature of from 160° C. to 200° 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.

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

摘要： A method for reducing curl in a stored photographic film which aids in preventing serious difficulties with downstream film transport and handling of the film. The film, which has been stored as a roll wound on a first core or mandrel is unwound from the first core and wound onto a second core or mandrel in a first direction. The film is then unwound from the second core to yield a traveling web portion. The traveling web portion is preheated to a predetermined temperature while being continuously delivered to a housing. The film is wound onto a third core or mandrel located within the housing in a direction opposite the first direction where it is maintained at about the same predetermined temperature.
