ABSTRACT:
Disclosed are electrophotographic elements comprising a support having coated thereon a photoconductive composition comprising a photoconductor dispersed in a linear film-forming polyester resin having its terminal hydroxyl and carboxyl groups endblocked with aprotic groups. The aprotic groups reduce hydrogen bonding within the resin matrix, and enhance the flowability of the resin when heated. Electrophotographic elements utilizing polyester resin binders endblocked in accordance with the present invention possess improved fusibility as compared with similar electrophotographic elements containing equivalent but protic endblocked polyester matrices, and as a result can be readily developed by flash fusing. In addition, such electrophotographic elements containing polyester resin binders endblocked in accordance with the instant invention possess improved photographic speed, and often improved dark decay properties, as compared with electrophotographic elements containing protic endblocked polyester matrices.
