TRANSPARENT INK-JET RECORDING FILMS, COMPOSITIONS, AND METHODS
The compositions and methods of the present application can provide transparent ink-jet recording films with increased image-receiving layer thicknesses. Such films can exhibit high maximum optical densities and rapid ink drying.
1 . A method comprising:
forming a first composition comprising gelatin;
forming a second composition by a first method comprising adding at least one borate or borate derivative to the first composition, the second composition comprising at least one anionic polymer; and
forming a transparent ink-jet recording film by a second method comprising forming at least one under-layer from the second composition.
2 . The method according to claim 1 , wherein the second method further comprises:
forming a third composition comprising at least one inorganic particle and at least one water soluble or water dispersible polymer comprising at least one hydroxyl group; and
forming at least one image-receiving layer from the third composition, the at least one image-receiving layer being disposed on the at least one under-layer.
3 . The method according to claim 2 , wherein the at least one inorganic particle comprises boehmite alumina.
4 . The method according to claim 2 , wherein the at least one water soluble or water dispersible polymer comprises polyvinyl alcohol.
5 . The method according to claim 1 , wherein the at least one borate or borate derivative comprises at least one hydrate of sodium tetraborate.
6 . The method according to claim 1 , wherein the at least one borate or borate derivative comprises sodium tetraborate decahydrate.
7 . The method according to claim 1 , wherein the at least one anionic polymer comprises polystyrene sulfonate.
8 . The method according to claim 1 , wherein the first method comprises:
adding the at least one borate or borate derivative to the first composition to form a fourth composition; and
combining the at least one anionic polymer and the fourth composition to form the second composition.
9 . The transparent ink-jet recording film prepared according to the method of claim 1 .
10 . A transparent ink-jet recording film exhibiting superior ink-drying performance prepared by a method comprising:
forming a first composition comprising gelatin;
forming a second composition by a first method comprising adding at least one borate or borate derivative to the first composition, the second composition comprising at least one anionic polymer; and
forming the transparent ink-jet recording film by a second method comprising forming at least one under-layer from the second composition.
