The present invention is a photographic element which includes a support, at least one silver halide emulsion superposed on a front side of the support and an outermost backing layer superposed on a backside of the support. The outermost backing layer is composed of a hydrophobic binder and a hydrophilic binder wherein the backing layer has an advancing water contact angle of 70 or greater and a receding water contact angle of at least 40 less than the advancing water contact angle.

Backing layers with reduced scum formation for photographic films

The present invention is recyclable photographic film base which includes a cellulose acetate support. An antistatic layer is superposed on one side of the support and includes an antistatic agent. A barrier layer comprising a polymeric composition having a glass transition temperature of less than 90.degree. C. overlies the antistatic layer. In a preferred embodiment the polymeric composition of the barrier layer in poly(isobutyl methacrylate).

Recoverable backings for cellulose acetate film support

The present invention discloses a three layer backing system for a photographic element. The backing system in on the opposite side of the light-sensitive layer. The backing system includes a first antistatic layer having an antistatic agent. The backing system includes a barrier layer of a polymer. The overcoat layer, farthest from the support, includes cellulose acetate and cellulose nitrate in a ratio range of from 3:1 to 1:1 and from 5 to 40 percent perfluorinatied polymer particles.

Three-layer backing for photographic element

The present invention provides a UVA protective eyeshield that includes a transparent substrate having dispersed therein an effective amount of 1-di-n-hexylamino-4,4-dicyanobutadiene.

Protective eyeshield

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.
