Patent ID: 7759032

Claim:
An electrophotographic imaging member comprising: a substrate, a charge generating layer, a charge transport layer, and an overcoating layer, said overcoating layer comprising a terphenyl arylamine dissolved or molecularly dispersed in a cured polyester polyol or a cured acrylated polyol, wherein: the terphenyl arylamine is represented by the formula: where each R 1 and R 2 are independently selected from the group consisting of —H, —OH, —C n H 2n+1 where n is from 1 to about 10, aralkyl, and aryl groups, the aralkyl and aryl groups having from about 5 to about 30 carbon atoms; the cured polyester polyol is represented by the formula: (—CH 2 —R a —CH 2 ) m —(—CO 2 —R b —CO 2 —) n —(—CH 2 —R c —CH 2 ) p —(—CO 2 —R d —CO 2 —) q where R a and R c independently represent linear alkyl groups or branched alkyl groups derived from the polyols, the alkyl groups having from 1 to about 20 carbon atoms; R b and R d independently represent alkyl groups derived from polycarboxylic acids, the alkyl groups having from 1 to about 20 carbon atoms; and m, n, p, and q represent mole fractions of from 0 to 1, such that n+m+p+q=1; and the cured acrylated polyol is represented by the formula: (R t —CH 2 ) m —(—CH 2 —R e —CH 2 ) p —(—CO—R f —CO—) n —(—CH 2 —R g —CH 2 ) p —(—CO—R h —CO—) q where R t represents CH 2 CR 1 CO 2 — where R 3 =an organic group, where R e and R g independently represent linear alkyl or alkoxy groups or branched alkyl or alkoxy groups derived from the polyols, the alkyl and alkoxy groups having from 1 to about 20 carbon atoms; R f and R h independently resent alkyl or alkoxy groups, the alkyl and alkoxy groups having from 1 to about 20 carbon atoms; and m, n, p, and q represent mole fractions of from 0 to 1, such that n+m+p+q=1.
