TRANSPARENT INK-JET RECORDING FILMS, COMPOSITIONS, AND METHODS
Transparent ink-jet recording films, compositions, and methods are disclosed. These compositions and methods can impart excellent adhesion properties between film layers and the transparent support. The films have improved appearance compared to similar high optical density films. Such improved appearance films are produced without requiring reduced drying process throughput. These films are useful for medical imaging.
1 . A transparent ink-jet recording film comprising:
a transparent substrate comprising a polyester;
at least one subbing layer disposed on the transparent substrate, the at least one subbing layer comprising gelatin, at least one polymeric matting agent, and at least one borate or borate derivative; and
at least one image-receiving layer disposed on the at least one subbing layer, the at least one image-receiving layer comprising at least one water soluble or water dispersible polymer and at least one inorganic particle, the at least one water soluble or water dispersible polymer comprising at least one hydroxyl group.
2 . The transparent ink-jet recording film according to claim 1 , further comprising at least one primer layer disposed between the transparent substrate and the at least one subbing layer, the at least one primer layer comprising at least one latex polymer and at least one adhesion promoter.
3 . The transparent ink-jet recording film according to claim 2 , wherein the at least one adhesion promoter comprises resorcinol.
4 . The transparent ink-jet recording film according to claim 1 , wherein the at least one polymeric matting agent comprises a copolymer comprising recurring units comprising methyl methacrylate.
5 . The transparent ink-jet recording film according to claim 1 , wherein the at least one borate or borate derivative comprises sodium tetraborate decahydrate.
6 . The transparent ink-jet recording film according to claim 1 , wherein the at least one water soluble or water dispersible polymer comprises poly(vinyl alcohol).
7 . The transparent ink-jet recording film according to claim 1 , wherein the at least one inorganic particle comprises boehmite alumina.
