1. Field of the Invention
The present invention relates to a primer coating for a polyester film to be primarily employed as a photographic film. The primer coating composition is applied to at least one side of a polyester film to improve the bonding between the film and one or more gelatin layers. The primer coating consists of a copolyester composition which is water-dispersible and suitable surfactant. It has been found that this primer coating composition is excellent for use in photographic films and yields superior adhesion performance over known aqueous-based photographic films. It has also been found that the primer coated film may be employed for non-photographic uses such as for diazo film, copier film, and drafting film.
