1. A transparent ink-jet recording film comprising:
- a transparent substrate comprising a polyester, said substrate comprising at least a first surface and a second surface;
at least one under-layer disposed on the first surface, said at least one under-layer comprising gelatin and at least one borate or borate derivative;
at least one image-receiving layer disposed on the at least one under-layer, said at least one image-receiving layer comprising at least one inorganic particle and at least one water soluble or water dispersible polymer comprising at least one hydroxyl group; and
at least one back-coat layer disposed on the second surface, said at least one back-coat layer comprising gelatin and at least one core-shell particle comprising at least one thermoplastic polymer.

Abstract
Transparent ink-jet recording films, compositions, and methods are disclosed. These films can exhibit high maximum optical densities, rapid ink drying, low curl, excellent adhesion between the coating layers and the substrate, and negligible ink transfer between stacked ink-jet recording films after imaging. Such films are useful in medical imaging applications.
