Abstract

An imaging method based on the generation of an electron ac-ceptor mølecute in. a matrix composed of or containing an dee-tron donor molecule. The method exploits the thermal or photedhemical teactioña of tetracyanocyctobutane derivatives of iron group alkenylmetallocenes and other electron rich polymers, 1 vinylcarbazole, vinylanthracene, vinylpyrrol-idone, etc. these derivatives can be combined with a material such as polystyrene and cast as .a film. . The film is then imaged thermally or photochemically to cause ring opening of the cyclobutane ring and formation of a charge-transfer com-plex between the . tricyanobutadienyl residues and the polysty-rene matrix thus providing coloration of the heated or exposed areas of the film. The coLor obtained in the imaged areas is dependent upon the nature of the binder and the concentration of the cyclobutane derivative incorporated therein.
