A process for making a photographic film support comprising applying a film forming coating composition containing an antistat agent to a first clear transparent polymeric film to form an antistat layer on the polymeric film and overcoating the free surface of the antistat layer with a second polymeric film having the same chemical composition as the first polymeric film.

Silver halide photographic film utilizing cellulose triacetate support

An apparatus 10 and method for removing contaminants from a web conveying roller 12 in a machine enclosure 14 comprises a cleaning head 16 that is manually operably controlled external to the machine enclosure 14 so as to resist introducing foreign contaminants into the machine enclosure 14 and reduce environmental emissions. The cleaning head 16 slidably moves lengthwise along the roller to a predetermined location under the influence of first rotatable shaft 30 and is urged into contact with the roller 12 and retracted therefrom under the influence of second rotatable shaft 40.

A method of making cellulose ester photographic film base employing microwave radiation for removing the final portion of solvent present in the film.

Method of making cellulose ester photographic film base

A photographic element comprising a photosensitive layer, a flexible cellulose organic ester support film, and a substantially transparent magnetic recording layer having a dried thickness of less than about 1.5 micron exhibits improved magnetic and photographic performance and is particularly valuable as a color or black and white negative or reversal film. A method of preparing the above-described element comprises the steps of

Photographic element containing thinb transparent magnetic recording

A blend of a cellulose and up to 5 percent by weight of a polyesterether resin and photographic film base having improved tear strength prepared from the blend.
