ABSTRACT:
A process is disclosed for increasing the radiation sensitivity of a layer containing a polyacetylenic material while at the same time extending its radiation sensitivity towards longer wavelengths. The process comprises applying a substantially uniform electric field across the polyacetylenic containing layer and imagewise exposing the layer while the electric field is uniformly applied. Novel elements capable of recording images from two different portions of the electromagnetic spectrum are also disclosed.
