An electroluminescent (EL) device includes a polymeric tetraaryl substituted biphenyldiamine.

Electroluminescent device

An electroluminescent (EL) device has a ceramic electroluminescent active layer and may be prepared by forming layers by a sol-gel process.

An electroluminescent device includes a light emitting layer made of a conjugated polymer that is prepared using halogen precursor route chemistry.

A photoresponsive imaging member comprised of a supporting substrate, a photogenerating layer, and a hole transporting layer comprised of a polysilylene stabilized with a component possessing an ionization potential equal to or greater than the polysilylene.

Stabilized polysilylenes and imaging members therewith

A multi-layer optical recording member for use with a recording laser for optical recording and retrieving information thereon, as well as a method of fabricating and using said member is described. The optical recording member comprises in sequential order a structural substrate, a thermally degradable polymer layer, a light absorbing recording layer, a thermally degradable polymer dielectric layer, and a reflective layer. The substrate and the thermally degradable polymer layers are stable under ambient light and temperature conditions and substantially transparent to the recording and reading optical radiation. The combined thicknesses of the light absorbing layer and the dielectric layer are such as to provide anti-reflecting conditionsat the recording wavelength and optical contrast between marked and unmarked areas at the reading wavelength. The optical recording member may be used with a single laser source for both recording and reading. Upon exposure to recording radiation, the portion of the light absorbing layer exposed is heated by the absorbed energy which in turn heats adjacent areas of both thermally degradable polymer layers to a level where at least some polymer decomposition with a consequent evolution of gaseous decomposition products occurs resulting in the formation of a hole in the exposed area of the heat absorbing layer.

Disclosed is an ablative infrared sensitive optical recording composition containing as a component thereof a dispersion of a resinous binder and an absorbing infrared sensitive tertiary butyl substituted vanadyl phthalocyanine obtained by the vapor treatment of a non-infrared sensitive tertiary butyl substituted vanadyl phthalocyanine of the following formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are tertiary butyl groups, or hydrogen, and M is vanadium oxide, subject to the provision that the average number of tertiary butyl groups present is from about 1 to 2.5, and at least one of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 is tertiary butyl.

Infrared sensitive phthalocyanine compositions

Disclosed is an ablative infrared-sensitive optical recording composition containing as a component thereof a dispersion of a resinous binder and a soluble naphthalocyanine of the following formula: ##STR1## wherein R.sub.5 and R.sub.6 are independently selected from hydrogen and alkyl groups containing from about 4 carbon atoms to about 8 carbon atoms, and M is two hydrogen atoms, a divalent, trivalent, or tetravalent metal complex.

Ablative infrared sensitive devices containing soluble naphthalocyanine

An optical recording member for storing data by the selective ablation of a layer of energy absorbing material by laser address including a layer of recording material and at least one layer of a polymeric material having a second order glass transition temperature less than 293.degree. K. contiguous to at least one surface of the layer of recording material.

An improved electrostatographic process wherein the imaging surface of the imaging member is treated with a lubricating effective amount of a compound selected from the group consisting of ortho-, meta-, para-phthalic acid, their corresponding metal or ammonium salts, and mixtures thereof. Controlled treatment of the imaging surfaces of the imaging member with the above compound(s) facilitates transfer of the developed image from the imaging member to a receiving sheet and removal of toner residues from the imaging surface upon cleaning. The imaging member element of the apparatus used in carrying out this process is covered with a thin film of lubricant over substantially all of its imaging surface thereby greatly improving toner transfer and removal.
