Abstract
A non-absorbing barrier layer for photographic printing paper includes a non-polyolefin resin. A photographic printing paper includes a base substrate; a image receiving layer and a barrier layer comprising a non-polyolefin resin coated on the base substrate. A method of making a photographic printing paper includes coating a barrier layer comprising a non-polyolefin resin on a base substrate. Another method of making a photographic printing paper includes forming a barrier layer on a base substrate using reactive monomers.
Claims12
A method of making a photographic printing paper comprising:
- forming a liquid coating composition comprising:
- a non-ionic surfactant;
- and
- a water soluble or water dispersible non-polyolefin resin;
- coating a paper base substrate with the liquid coating composition via a non-extrusion coating method to form a non-absorbing barrier layer;
- and
- depositing an image-receiving layer on an upper surface of the non-absorbing barrier layer.
A method of making a photographic printing paper comprising:
- forming a liquid coating composition comprising:
- a non-ionic organosilicone surfactant;
- and
- a water soluble or water dispersible non-polyolefin resin,
- in which an amount of the non-ionic organosilicone surfactant comprises between 0.1 and 1% by weight of the total weight of the non-polyolefin resin;
- coating both sides of a paper base substrate via a non-extrusion liquid coating method to form a non-absorbing barrier layer;
- and
- depositing image-receiving layers over and adjoining the barrier layers on both sides of the paper base substrate.
