摘要：
An imaging system and process wherein an element comprising a cobalt complex-developer redox system is catalyzed by cobalt sulfide. The cobalt sulfide can be imagewise produced by exposing a photoreducible cobalt complex in the presence of a thioamide, or it can be uniformly distributed and either masked in an imagewise fashion, or reacted with imagewise distributed color developing agent.
