ABSTRACT:
An opaque recording material has an opaque sensitive layer which can be transparentized by application of heat or a suitable solvent for the opacifying styrene resin pigment which is dispersed in a polyvinylidene chloride film-forming resin binder. In a particular application, useful for overhead transparencies or for making photographic negatives for reproduction, heat and solvent are both applied to the opaque layer in selected different areas to transparentize the opaque layer. The opaque layer may be deposited on a transparent clear or colored support such as transparent polyester.
