Abstract
Photoconductive compositions having both high-speed and high-resolution are disclosed. The composition comprises a film forming electrically insulating polymer and a dye in the form of a dye-dye complex, having a structure according to the formula ##STR1## wherein X.crclbar. represents an anion; the dye has an absorption spectrum which changes when a binderless coating of the dye is treated with solvent vapors, and the composition containing the dye-dye complex has an absorption spectrum which is similar to the changed absorption spectrum of the dye when treated with solvent vapors.
