STABLE ANTIHALATION MATERIALS FOR PHOTOGRAPHIC AND PHOTOTHERMOGRAPHIC ELEMENTS

摘要

An infrared photosensitive element comprising: a support bearing an infrared radiation-sensitive silver halide material; and an antihalation layer comprising a basic antistatic agent, an acid having a pKa less than 4.2 in an amount equal to at least 1.0 % mole equivalent of acid to 1 mole equivalent of amine in said antistatic agent, and sufficient antihalation dye to provide a transmission optical density at the wavelength of maximum absorbance of said dye of at least 0.2 after coating.
