An electrophotographic photosensitive member that can not easily cause charging lines even where it is an electrophotographic photosensitive member employing as a conductive layer a layer containing metal oxide particles is disclosed. Also disclosed are a process cartridge and an electrophotographic apparatus which have such an electrophotographic photosensitive member. The electrophotographic photosensitive member has a conductive layer which contains titanium oxide particles coated with tin oxide doped with phosphorus or tungsten.

An audio/video distribution system for a multiple dwelling unit provides programming which is selectable by a subscriber through the interactive use of on-screen menus. Programming and services are supplied from a headend (12) over a distribution network (20) to individual apartments, which network includes an interdiction field unit (28) associated with each of a group of apartments. The interdiction field unit normally interdicts those channels capable of carrying VOD movies, interactive games, and interactive services. When a subscriber wishes to order a selection through interactive on-screen menus provided from the headend to the apartment, the headend instructs the interdiction field unit associated with the subscriber's apartment to de-interdict a channel. Selections made through a remote control to a subscriber terminal in the apartment are supplied to the headend over the distribution system. The channel remains deinterdicted during play of a selection, based upon the signals received from the subscriber terminal during the interactive on-screen menu session.

Disclosed is an organic electroluminescent element which is excellent with respect to luminous efficiency and driving voltage and rarely undergoes initial luminance drop. Specifically disclosed is an organic electroluminescent element which comprises, on a substrate, a pair of electrodes composed of an anode and a cathode and a light-emitting layer arranged between the electrodes, and additionally comprises at least one organic layer arranged between the light-emitting layer and the cathode, where in the light-emitting layer contains, for example, a compound (A-1), and the at least one layer arranged between the light-emitting layer and the cathode contains, for example, a compound (e-4).

Organic electroluminescent element

Described is a process for producing adherent layer(s) on organic polymeric substrates following the steps of (a) treating the surface of the polymeric substrate to provide reactive groups; (b) applying to the surface a polymerizable composition of organic anhydrides, isocyanates and/or a mixture thereof that is substantially free of organosiloxanes; and (c) curing the polymerizable coating. Further steps include applying an additional layer which is substantially free of organosiloxanes and that may or may not contain the polymerizable composition of the present invention. Also described are products produced by the process that may be transparent, tinted, tinted and polarized or photochromic.
