Abstract
A photoconductive laminate and its use are disclosed, the laminate comprising two layers of compounds, each layer being a single phase and at least one of the compounds having a generally planar polycyclic nucleus.
Claims7
A photoconductive laminate comprising
- a single-phase layer of an organic electron-donor compound containing a generally planar polycyclic nucleus,
- and in contact with said layer, a single-phase layer of a photoconductive organic dye having the structure ##STR33## wherein:
- J is ##STR34## or N;
- D.sup.1 and D.sup.2 are the same or different and are each the non-metallic atoms necessary to complete a heterocyclic 6-membered ring containing O, S, or Se as a ring atom;
- R.sup.8, R.sup.9 and R.sup.10 are the same or different and are each H, alkyl from 1 to about 3 carbon atoms, aryl, cyano or nitro;
- R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are the same or different and are each phenyl, or alkyl or alkoxy containing from 1 to about 5 carbon atoms, at least two of R.sup.1, R.sup.2, R.sup.3 and R.sup.4 being phenyl;
- m is 1 or 0 and is 0 if J is N;
- and Z.sup..crclbar. is an anion.
