Abstract
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 photographic elements designed for development with heat.
