摘要： Photothermographic materials comprise heat-bleachable antihalation compositions in backside antihalation layers. These compositions comprise a hexaarybiimidazole and an oxonol dye that can be represented by the following Structure I:
wherein A 1 and A 2 are the same or different activated methylene moieties, L 1 through L 7 independently represent a substituted or unsubstituted methine group, M represents a counterion, k is the number of M counterions necessary to provide neutral charge for Structure I, p, and q, are independently 0 or 1, and r is 0, 1, or 2. The antihalation composition is typically bleached when subjected to a temperature of at least 90°C for at least 0.5 seconds.
