ABSTRACT:
A photothermographic element can comprise a support and on the support or in the support an antihalation or filter component that comprises a heat bleachable material comprising (i) at least one hexaarylbiimidazole with (ii) at least one dye, especially an antihalation or filter dye, that is reactive with the product of the hexaarylbiimidazole formed upon heating the material to a temperature above about 90.degree. C. This provides an antihalation or filter material that becomes at least 40% colorless within about 20 minutes, typically within about 30 seconds, upon heating to a temperature as described. The antihalation or filter material can be a heat bleachable dye layer of a photothermographic element.
