METAL FILM IMAGING STRUCTURE Abstract of the Disclosure An image-forming laminate is formed by the com- bination of a thin, frangible light opaque material on top of a photosensitive layer which changes its surfactant properties when irradiated, The photosensitive layer according to the present invention comprises a film-forming polymeric binder, a photosensitive acid generator, and a surfactant selected from nonionic surfactants, the neutral form of cationic surfactants, amphoteric surfactants, and surfactant acid salts. Preferably the frangible light opaque material is a thin metal layer. There can also he present a support layer on the other surface of the photosensitive layer, as well as there can he an adhesive layer secured to the upper surface of the frangible light opaque material. The strength of adherence of the adhesive layer to the metal should be intermediate the strength of the adherence of the light opaque material prior to and after photoactivation.
