ABSTRACT:
This invention is generally directed to an organic layered photoresponsive device containing a charge transport layer comprised of a composition of the following: ##STR1## dispersed in a highly insulating and transparent organic resinous material, wherein x is selected from the group consisting of ortho (CH.sub.3), meta (CH.sub.3), para (CH.sub.3), ortho (Cl), meta (Cl), and para (Cl), and dispersed in said transport layer from about 0.1 weight percent to about 10 weight percent of an additive composition selected from the group consisting of ##STR2## wherein R and R.sub.1 are independently selected from the group consisting of ethylene groups containing from about 1 to about 6 carbon atoms such as methylene, ethylene, propylene, butylene and the like, and n is 0 or 1; ##STR3## wherein R.sub.2 and R.sub.3 are independently selected from alkyl groups containing from about 1 to about 6 carbon atoms, and R.sub.4 is selected from the group consisting of alkyl groups containing from about 1 to about 6 carbon atoms, CH.sub.2 OH, (CH.sub.3).sub.2 OH, and ##STR4## wherein R.sub.2 is an alkyl group; ##STR5## wherein R.sub.6 and R.sub.7 are alkyl groups; and ##STR6## wherein R.sub.8, R.sub.9, R.sub.10, and R.sub.11 are alkyl groups.
