THERMALLY DEVELOPABLE IMAGING MATERIALS AND METHODS

摘要

A thermally developable material comprising a support and having thereon at least one non-photosensitive carrier layer comprising: a binder comprising vinyl butyral repeat units and alcohol repeat units, an adhesion promoting compound comprising ester repeat units, and a crosslinker comprising isocyanate repeat units; and at least one thermally developable imaging layer comprising organic silver salt grains, light-sensitive silver halide grains, a reducing agent, a binder comprising hydroxyl and butryal repeat units, and a crosslinker comprising at least one isocyanate group.

1. A thermally developable material comprising a support and having thereon:
at least one non-photosensitive carrier layer comprising at least one first binder comprising first vinyl butyral repeat units and first vinyl alcohol repeat units, at least one adhesion promoting compound, and at least one first crosslinker comprising first isocyanate groups; and at least one thermally developable imaging layer comprising organic silver salt grains, light-sensitive silver halide grains, at least one reducing agent, at least one second binder comprising second vinyl butyral repeat units and second vinyl alcohol repeat units, and at least one second crosslinker comprising second isocyanate groups, wherein the equivalent ratio of the first vinyl alcohol repeat units to the second isocyanate groups is no greater than about 56.
