    摘要: A process for forming finely divided squaraine particles is disclosed comprising dissolving squaraine material in an organic base selected from the group consisting of primary organic amines and secondary organic amines, neutralizing the organic base with an acid selected from the group consisting of organic acids and inorganic acids thereby precipitating the squaraine material as finely divided particles in a liquid medium, and separating the finely divided particles from the liquid medium.

    摘要: Photoconductive compositions comprising an insulating polymeric matrix and a compound of the formula ##STR1## wherein R is --H or --CN;R', r", r'" and R.sup.iv are independently selected from an aliphatic hydrocarbon radical having from about 1 - 10 carbon atoms; phenyl; or substituted phenyl wherein said substituents are capable of releasing electrons to relatively electron deficient centers within the compound; amino; diarylamino; dialkylamino or alkoxy; n can range from 0 up to the potential number of positions of substitution on the aromatic ring system. These compositions have good spectral response in the visible region of the electromagnetic spectrum and are suitable for use in electrostatographic imaging members and methods.

    摘要: Photoconductive composition comprising a carbazole functional polymer wherein at least 0.1 percent of said carbazole function groups have the following structural formula ##SPC1##wherein X is a structural unit of said polymer; R is hydrogen; an aliphatic hydrocarbon radical having from 1 - 10 carbon atoms; phenyl; or substituted phenyl, said phenyl substituents being capable of contribution of electrons to relatively electron deficient centers with the structural unit.Materials of the above structural formula can be readily polymerized or copolymerized with other addition polymers. These polymer compositions are useful in preparation of photoconductive insulating layers for electrophotography.
