Abstract
In accordance with the present invention there is provided an organic compound having the formula selected from the group consisting of: ##STR1## wherein x is an integer from 0 to 2, y is an integer from 1 to 6, and z is an integer from 0 to 2; ##STR2## wherein L is aliphatic, alicyclic or aromatic and a is an integer from 2 to 6; and wherein G has the formula ##STR3## wherein n is an integer from 0 to 6 and Q.sub.1, Q.sub.2, Q.sub.3, Q.sub.5, Q.sub.6, and Q.sub.7, which may be the same or different, represent H or CH.sub.3, and Q.sub.4 represents H or CH.sub.3 when x and z are 0 or n is greater than 0, or Q.sub.4 represents CH.sub.3 when x or z are 1 or 2 and n is 0. The compounds, which exhibit unexpectedly high T.sub.g and unexpectedly high resistance to oxidation, are useful in electrophotographic elements.
