【発明の属する技術分野】
本発明は、電子写真用の有機光導電性材料として、またヒドロキシル基から誘導される種々の材料の製造中間体として有用なジヒドロキシル基含有ジアミン化合物に関する。
【0002】
【従来の技術】
従来、電子写真方式において使用される感光体の有機光導電性材料としては、例えば、ポリ−N−ビニルカルバゾール、トリフェニルアミン化合物(米国特許第3,180,730号)、ベンジジン化合物(米国特許第3,265,496号、特公昭39−11546号公報、特開昭53−27033号公報)等のような数多くの提案がなされている。
【0003】
ここに言う「電子写真方式」とは、一般に光導電性の感光体を、先ず暗所で、例えばコロナ放電などにより帯電せしめ、次いで画像状露光を行って露光部の電荷を選択的に放電させることにより静電潜像を得、更にこの潜像部をトナーなどを用いた現像手段で可視化して画像を形成するようにした画像形成法の一つである。このような電子写真方式における感光体に要求される基本的な特性としては、1)暗所において適当な電位に帯電されること、2)暗所において電荷の放電が少ないこと、3)光照射により速やかに電荷を放電すること、などがあげられる。
【0004】
また、近年において、感光体の更なる機械的強度の向上を目的として高分子光導電性材料(米国特許第4,801,517号、米国特許第4,806,443号、米国特許第4,806,444号、特開平3−221522号、特開平4−11627号)が提案されている。
【0005】
しかしながら、従来の低分子あるいは高分子光導電性材料は、前記の要求を必ずしも満足していないのが実状である。
【0006】
【発明が解決しようとする課題】

Conventionally, organic photoconductive materials for photoreceptors used in electrophotography include, for example, poly-N-vinylcarbazole, triphenylamine compounds (US Pat. No. 3,180,730), and benzidine compounds (US Pat. A number of proposals have been made, such as Japanese Patent No. 3,265,496, Japanese Patent Publication No. 39-11546, and Japanese Patent Application Laid-Open No. 53-27033.
[0003]
As used herein, the term "electrophotographic method" generally means that a photoconductive photoconductor is first charged in a dark place, for example, by corona discharge, and then imagewise exposed to selectively discharge charges in exposed portions. This is one of the image forming methods in which an electrostatic latent image is obtained, and the latent image portion is visualized by a developing unit using toner or the like to form an image. The basic characteristics required of the photoreceptor in such an electrophotographic system include: 1) being charged to an appropriate potential in a dark place, 2) being less discharged in a dark place, and 3) being irradiated with light. Discharging the charge more quickly.

[0005]
However, conventional low-molecular or high-molecular photoconductive materials do not always satisfy the above requirements.
[0006]
[Problems to be solved by the invention]
It is an object of the present invention to be useful as a photoconductive material which satisfies all basic electrophotographic properties by itself, and various materials derived from hydroxyl groups, for example, a polycarbonate resin for electrophotography.
