    • Disazo compounds represented by the following general formula (I) are disclosed. The compounds can function as effective photoconductive substances and further, as efficient charge carrier (both electron and positive hole) generating compounds in an electrophotographic photoreceptor: ##STR1## (wherein X represents atoms necessary to form an aromatic ring, such as a naphthalene ring, an anthracene ring, etc., or a netero ring, such as an indole ring, a carbazole ring, a dibenzofuran ring etc., (all of which rings may be either substituted ones or nonsubstituted ones) by combining with the benzene ring to which a hydroxyl group and a group Y are attached; Y represents ##STR2## R.sup.1 represents an alkyl group, a phenyl group or a substituted group thereof; R.sup.2 represents a hydrogen atom, a lower alkyl group, a carbamoyl group, a carboxyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, or a substituted or a nonsubstituted amino group; R.sup.3 and R.sup.5 each represents an alkyl group, an aromatic ring residue like a phenyl group, an aromatic heterocyclic residue like a dibenzofranyl group, a carbazolyl group, etc., or a substituted group thereof; and R.sup.4 represents a hydrogen atom, an alkyl group, a phenyl group or a substituted group thereof).
    • 公开了由以下通式（I）表示的双偶氮化合物。 这些化合物可以起到有效的光电导物质的作用，而且作为在电子照相感光体中产生化合物的有效电荷载体（电子和空穴）都是有效的：其中A表示 + TR ，B表示 + TR （其中X表示形成芳环所需的原子，如萘环，蒽环等，或网络环，如吲哚 环，咔唑环，二苯并呋喃环等（所有这些环可以是取代的环或非取代的环）通过与其中连接有羟基和Y的苯环组合; Y表示< 表示烷基，苯基或取代基; R2表示氢原子，低级烷基，氨基甲酰基，羧基，烷氧基羰基，芳氧基羰基或取代或未取代的氨基; R3和R5各自表示 烷基，芳香环残基如苯基，芳族杂环残基如二苯并呋喃基，咔唑基等，或其取代基; R4表示氢原子，烷基，苯基或取代基）。

    • A photoconductive composition is disclosed, containing at least one trisazo compound represented by the following general formula (1): ##STR1## wherein Z represents ##STR2## R.sup.6 represents a hydrogen atom, a lower alkyl group, an aryl group, an aryloxy group, an alkoxycarbonyl group, an aryloxycarbonyl group, an acyl group, or a substituted group of them; As', which may be the same or different, each represents ##STR3## B.sup.1, B.sup.2 and B.sup.3 each represents a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group or a substituted lower alkyl group or lower alkoxy group, and B.sup.1, B.sup.2 and B.sup.3 may be identical or different; X represents an atomic group necessary to form an aromatic ring or heterocyclic ring, which may be substituted or unsubstituted, by condensing with the benzene ring to which the hydroxyl group and Y are bonded; Y represents ##STR4## R.sup.1 represents an alkyl group, a phenyl group or a substituted alkyl or phenyl group; R.sup.2 represents a hydrogen atom, a lower alkyl group, a carbamoyl group, a carboxyl group, an alkoxycarbonyl group, an aryloxycarbonyl group or a substituted or unsubstituted amino group; R.sup.3 represents an alkyl group, an aromatic group or a heteroaromatic group or a substituted alkyl group, aromatic group or heteroaromatic group; and R.sup.4 and R.sup.5, which may be the same or different, each represents a hydrogen atom, an alkyl group, an aromatic group, a heteroaromatic group or a substituted alkyl group, aromatic group or heteroaromatic group, provided that R.sup.4 and R.sup.5 are not both hydrogen atoms, and R.sup.5 is not a hydrogen atom when Y is ##STR5## . An electrophotographic light-sensitive material is also disclosed, comprising an electrically conductive base and a layer containing an electric charge carrier transport compound and the trisazo compound as an electric charge carrier generating compound.
