Abstract
A hydroxy arylamine compound is disclosed represented by the formula: ##STR1## wherein: m is 0 or 1, PA1 Z is selected from the group consisting of: ##STR2## n is 0 or 1, Ar is selected from the group consisting of: ##STR3## R is selected from the group consisting of --CH.sub.3, --C.sub.2 H.sub.5, --C.sub.3 H.sub.7, and --C.sub.4 H.sub.9, PA1 Ar' is selected from the group consisting of: ##STR4## X is selected from the group consisting of: ##STR5## s is 0, 1 or 2, the dihydroxy arylamine compound being free of any direct conjugation between the --OH groups and the nearest nitrogen atom through one or more aromatic rings. The dihydroxy arylamine compound may be employed in an electrophotographic imaging member and the member may be used in an electrophotographic imaging process.
