ABSTRACT:
In organic, photoconductive insulating compositions including one or more organic photoconductors, the image contrast characteristics obtained when using such compositions can be modified or modifiable when the composition includes a triaminobenzene compound, such as one having the formula ##SPC1##
Wherein each of Z, Z.sup.1 and Z.sup.2, taken together with the nitrogen to which each is attached, represents the non-metallic atoms necessary to complete a heterocyclic group having from 5 to 10 atoms in the cyclic nucleus.
