Abstract
The present invention relates to a polyester-based photographic support comprising: a polyester film, and a coating layer formed thereon by applying a coating solution containing an aqueous polyester and an aqueous epoxy group-containing compound so as to be a dry weight ratio of 30/70 to 90/10, on at least one side of said polyester film.
Claims17
A polyester-based photographic support comprising:
- a polyester film, and
- a coating layer formed thereon by applying a coating solution consisting essentially of an aqueous polyester and an aqueous epoxy group-containing compound so as to be a dry weight of aqueous polyester to aqueous epoxy group-containing compound of 30:70 to 90:10, on at least one side of said polyester film.
A polyester-based photographic support comprising:
- a polyester film, and
- a coating layer formed thereon by applying a coating solution consisting essentially of an aqueous polyester and an aqueous epoxy group-containing compound so as to be a dry weight of aqueous polyester to aqueous epoxy group-containing compound of 30:70 to 90:10, on at least one side of said polyester film, wherein the thickness of the polyester-based photographic support is 50 to 350 .mu.m.
A process for producing a polyester-based photographic support, which comprises applying a coating solution consisting essentially of an aqueous polyester and an aqueous epoxy group-containing compound so as to be a dry weight of aqueous polyester to aqueous epoxy group-containing compound of 30:70 to 90:10, on at least one side of a polyester film, and drying the coat.
A polyester-based photographic support comprising:
- a polyester film, and
- a coating layer formed thereon by applying a coating solution consisting essentially of an aqueous polyester and an aqueous epoxy group-containing compound so as to be a dry weight of aqueous polyester to aqueous epoxy group-containing compound of 30:70 to 90:10, on at least one side of said polyester film, wherein the photographic support further comprises at least one photosensitive layer provided on said support.
