Abstract
Irradiation of collected S.sub.4 N.sub.4 decomposition products with light or radiation in the .gamma. to visible range enhances the initiation of polymerization of the decomposition products to produce polysulfur nitride, which is typically conductive and usually referred to as (SN).sub.x. Irradiation of a masked coating of collected S.sub.4 N.sub.4 decomposition products and completion of polymerization thereof and removal of non-irradiated, non-polymerized portions thereof will result in an electrically conductive coating disposed in a preselected pattern. S.sub.4 N.sub.4 decomposition products may also be dispersed in a matrix, e.g. a photographic emulsion which is transparent or partially transparent to light, or which may be rendered partially or selectively transparent or opaque. This might be useful, for example, for imaging applications, or for producing a selectively transparent pattern for subsequent photoinduced initiation of polymerization of the S.sub.4 N.sub.4 products.
