The present invention relates to a photosensitive member containing a specific bisazo compound described by general structural formula[I] and formed on an electrically conductive substrate; ##STR1## Wherein X is a hydrogen atom, halogen atom, alkyl radical, alkoxi radical, nitro radical or cyano radical; A is a diatomic radical selected from among the following: ##STR2## B is a coupler described by formulae [II] through [VI]; ##STR3## R is a hydrogen atom, halogen atom, alkyl radical, alkoxi radical, nitro radical or cyano radical; and Y is an aromatic carbocyclic residue or aromatic heterocyclic residue, each of which may have a substituent; G is a carbamoyl radical or sulfamoyl radical and may have a substituent; R.sub.1 is a hydrogen atom, alkyl radical, amino radical or carbamoyl radical, each of which may have a substituent, a carboxyl radical or cyano radical; M is an aryl group which may have a substituent, which is improved in photosensitivity and dispersibility.

Photosensitive member comprising bisazo pigment

The present invention uses an azo pigment having in the center of an N-oxide heterocyclic structure as a photoelectrical charge-generating material. The pigments are excellent in dispersion stability in a dispersed solution, and enable the provision of a photosensitive member excellent in sensitivity properties.

Photosensitive member comprising azo compound having pyridine-n-oxide or

There is provided a novel method for producing 2,2-dimethyl-3-methylenebicyclo[2.2.1]heptan-5-ol and 2,2,3-trimethylbicyclo[2.2.1]heptan-3,5-diol and their lower fatty acid esters. Also provided are perfume, fragrance compositions containing 2,2-dimethyl-3-methylenebicyclo[2.2.1]heptan-5-ol or a lower fatty acid ester thereof, which has a fragrance characteristic of floral scent.

Method for production of

A method of producing aminobenzimidazolones which comprises reacting a compound I having the general formula ##STR1## wherein X, Y and Z independently represent a substituent selected from the group consisting of a nitro group and an amino group, with carbon monoxide in solvent in the presence of selenium and an inorganic base or an organic base, and in the presence of water when the compound I has nitro groups, thereby providing a compound II having the general formula ##STR2##

Method of producing aminobenzimidazolones

A method of producing benzimidazolone which comprises reacting a feed compound having the general formula ##STR1## wherein X and Y independently represent an amino group or a nitro group, with carbon monoxide in solvent in the presence of selenium and a base, and in the presence of water when the feed compound has nitro groups.
