摘要：
NOVEL PHOTOGRAPHIC MATERIALS COMPRISING A LIGHT-SENSITIVE LAYER AND A LIGHT-ABSORBING MATERIAL ARE DESCRIBED. THE LIGHT-ABSORBING MATERIALS COMPRISE COLORED COMPONENTS WHICH ARE DECOLORIZED BY VARIOUS FORMS OF ENERGY, SUCH AS, FOR EXAMPLE HEAT. THE NOVEL LIGHT-ABSORBING MATERIALS ARE USEFUL IN ANTIHALATION LAYERS PARTICULARLY ADAPTED FOR PHOTOTOGRAPHIC ELEMENTS DESIGNED FOR DEVELOPMENT WITH HEAT.
