As described in November 1977, page 5, it is useful as a spectral sensitizer for photoconductors, particularly for organic photoconductors.
チオピリリウム及びピリリウム染料により増感された光
導電体は上記の特許に開示されたような種々の用途に用

ファクス方式の電子写真用として重要である。Photoconductors sensitized with thiopyrylium and pyrylium dyes are used in a variety of applications such as those disclosed in the above-mentioned patents, but they are particularly important for xerographic and electrofax electrophotographic applications.
しかしながら、このような従来公知のチオピリリウム染

。However, since such conventionally known thiopyrylium dyes have an absorption band in the visible range, when these thiopyrylium dyes are used as a sensitizer for a photoconductor, a transparent photoconductive composition exhibiting absorption in the visible range can be obtained. I couldn't do anything.
従って、本発明の目的は、光導電体に対し高い増感能を
与える新規なチオピリリウム化合物を増感剤として含有

とである。Accordingly, it is an object of the present invention to provide a photoconductive composition comprising a photoconductive material containing a novel thiopyrylium compound as a sensitizer, which provides high sensitizing ability to a photoconductor.

である。Compound (1) Compound (2) ClO4- Compound (3) CIO,- Compound (5) Compound (6) I Compound (7) r The thiopyrylium salt used in the present invention has a main absorption in the far-infrared to near-infrared @ When this salt is used as a sensitizing dye for an organic photoconductor that does not absorb visible light, such as poly-N-vinylcarbazole, a colorless and transparent photoreceptor is created. I can do things. Therefore, even if a layer made of an organic photoconductor containing a thiopyrylium salt used in the present invention is provided on white paper, it is possible to provide an appearance similar to that of brain paper without a coating layer on the white paper. The photoreceptor made of an organic photoconductive substance containing a thiopyrylium salt is
In addition to being used in ordinary electrophotography using tungsten light as a light source, it is sensitive to far-infrared to near-infrared light, so it is particularly effective in electrophotography using a light source in this region (for example, a semiconductor laser). In addition, the thiopyrylium salt used in the present invention can be incorporated into photoconductive photosensitive particles in photoelectrophoresis electrophotography and used effectively as photoconductive photosensitive particles. Further, one of the excellent characteristics of the compound of the present invention is that the photoreceptor using the compound used in the present invention has high sensitivity.

することが、好ましい。Furthermore, when a thiopyrylium salt of zero invention is used as an aggravating agent for an inorganic photoconductive substance, it may not show sufficient sensitizing effect in the case of an organic photoconductive substance. This is because the thiopyrylium salt of the present invention has a slightly smaller adsorption power for inorganic photoconductive substances such as zinc oxide than organic photoconductive substances, and due to the presence of a third component such as a binder, the inorganic photoconductive substance This is thought to be caused by the desorption of thiopyrylium salt from the photoconductive substance. Therefore, in such cases, inorganic photoconductive materials (e.g. zinc oxide)
If an electrophotographic photoreceptor is manufactured by dispersing an inorganic photoconductive substance in a binder made of a resin that does not contain polar groups (such as carboxyl groups or hydroxyl groups) that have a strong affinity for This is completely achievable. That is, for inorganic photoconductive substances such as zinc oxide, it is preferable to use a resin containing almost no polar groups, such as polystyrene, styrene-butadiene copolymer, etc., as the resin binder.
