Abstract
Disclosed is a method for forming a visible image. The method involves exposing in an imagewise manner a mixture of a halogenated polymer having halogen atoms on alternating carbon atoms and a strong organic electron acceptor to actinic radiation to induce dehydrohalogenation of the polymer. The exposed composition is then subjected to heat in order to provide a visible image.
