ABSTRACT:
The present invention relates to a photoimaging process whereby a polymeric film containing sulfide functionality is selectively exposed to incident radiation in the presence of oxygen and a photosensitizer so that the sulfur functionality is photooxidized to produce a latent image which may then be developed. Polymeric films containing photooxidizable organic sulfide functionality and preferably additional carbon-carbon double bond unsaturation, which are capable of being used in the foregoing process are also included within the scope of the present invention.
