Abstract
A multi-active photoconductive element is disclosed having at least three layers in electrical contact with one another, said layers comprising a photoconductive selenium-containing layer, a charge-generation layer and an organic photoconductor-containing charge-transport layer. The charge-generation layer contains a continous polymeric phase having dispersed therein a co-crystalline complex composed of (i) at least one polymer having an alkylidene diarylene group in a recurring unit and (ii) at least one pyrylium-type dye salt. The multi-active element of the invention exhibits improved sensitivity to blue light.
