Abstract
Coating compositions and image forming materials made therefrom, the coating compositions comprising at least one non-photosensitive source of reducible silver ions, at least one reducing agent capable of reducing the reducible silver ions, a first binder comprising vinyl butyral repeat units and vinyl alcohol repeat units, a second binder comprising vinyl butyral repeat units and vinyl alcohol repeat units, the second binder having a composition differing from that of the first binder, and a third binder comprising vinyl pyrrolidone repeat units and vinyl acetate repeat units.
Claims5
