ABSTRACT:
High-speed black-and-white photothermographic materials can be imaged in any suitable fashion using ultraviolet, visible, infrared, or X-radiation. They can have one or more thermally developable imaging layers on either or both sides of the support and can be imaged with or without a phosphor intensifying screen in an imaging assembly. The photothermographic emulsions and materials have a net Dminless than 0.25, and require less than 1 erg/cm2to achieve a density of 1.00 above net Dmin.
