Abstract
The present invention provides novel composite electrically photosensitive particles. Each of said particle comprises a colorant and a polymeric binder comprising repeating units containing one or more structures selected from the classes consisting of triarylamines; p-aminotetraarylmethanes; 4,4'-bis(p-amino)triarylmethanes; 1,1-bis(p-aminoaryl)isobutanes; 1,1-bis(p-aminoaryl)cyclohexanes; N-alkyl-N,N-diarylamines; N,N-dialkyl-N-arylamines and heterocyclic nitrogen compounds having about 4 to 10 carbon atoms.
