A metal oxide coating and a method of forming the metal oxide coating are disclosed, wherein the metal oxide coating composition includes a metal oxide precursor of the metal oxide, the metal oxide, or a combination thereof, and a solvent of secondary or tertiary C&#x2013;Calcohol.

Metal oxide coating

A photographic support comprising; a polyester base having a first and a second side; an antistatic layer superposed on the first side of the base; a gelatin layer superposed on the second side of the base; and an auxiliary layer overlying said antistatic layer comprising 20 to 80 percent by weight hydroxypropyl methyl cellulose and a second binder.

Film support with annealable layer and improved adhesion

The present invention is a photographic element which includes a support, and at least one light-sensitive silver halide layer on a front side of the support. The photographic element has on the backside of the support an antistatic layer; a transparent magnetic recording layer; and a lubricating overcoat layer. The lubricating overcoat layer is farthest from the support and includes a lubricant of the general formula:

Imaging elements, such as photographic, electrostatographic and thermal imaging elements, are comprised of a support, an image-forming layer and an electrically-conductive layer produced by coating a layer comprised of a metallo-organic compound and a film-forming binder and subjecting such layer to glow discharge treatment to render it electrically conductive. Use of a metallo-organic compound in combination with a glow discharge treatment provides a controlled degree of electrical conductivity and beneficial chemical, physical and optical properties which adapt the electrically-conductive layer for such purposes as providing protection against static or serving as an electrode which takes part in an image-forming process.

Elements having a support with lubricant on both sides can be treated to remove substantially all of the lubricant from one side only. Various chemical, mechanical and electrical treatments are contemplated, but glow discharge treatment is particularly useful. Photographic film supports having one or more layers applied thereto can be treated in this manner before or after annealing so that lubricant present on the treated side does not reduce adhesion of later applied silver halide emulsion layers.
