摘要

AGGREGATE PHOTOCONDUCTIVE COMPOSITION CONTAINING COMBINATION OF PYRYLIUM TYPE DYE SALTS An aggregate or heterogeneous multiphase photoconductive composition containing a continuous polymer phase and at least one discontinuous phase dispersed in said continuous phase, said discontinuous phase comprising a co-crystalline complex of (i) at least one polymer having an alkylidene diarylene group in a recurring unit (ii) at least one pyrylium type dye salt having a non-light absorbing anion, and (iii) at least one pyrylium type dye salt having a colored organic or organo-metallic anion of a strong acid.
