Abstract: An electrophotographic recording medium which consists essentially of an electrically conductive base and a photosemiconductive double layer which comprises a first layer containing charge carrier-producing dyes, and a second layer containing one or more compounds which are charge carrier-transporting when exposed to light, wherein the charge carrier-producing dyes are those of the general formula I (I) where R1, R2 and R3 are each hydrogen, halogen, alkyl, nitro or cyano, R4 is phenyl, halophenyl, alkylphenyl, nitrophenyl or dialkylaminophenyl, and X is oxygen, sulfur, NH or N-phenyl, and the production of this recording medium.

Abstract: Monoazo dyes of formula (I) are new. In (I), K is the residue of a coupler; R is phenylthio or phenylsulphonyl opt. substd. by Cl, Br, CH3, CH3O, C2H5O, NO2 or SO3H; X = H, CL, Br or Cn. Pref. K has formula (II) In (II), R1 = h, CH3, CH3O or C2H5O. R2 is H, Cl, CH3, CH3O or 1-4C alkanoylamino. R3 = H, opt. substd. 1-4C alkyl, allyl, benzyl, phenethyl, cyclohexyl, phenyl or propargyl. R4 = opt. substd. 1-4C alkyl, allyl or propargyl. (I) are made by coupling a diazotised 2,4-dinitroaniline to HK. Used for dyeing or printing textiles, esp. polyester when no water-solubilising gps. are present.

Abstract: New azo dyes are of formula (I) (in which R1 is H, alkenyl, opt. substd. alkyl, cycloalkyl, aralkyl, aryl or heteroaryl; K is the gp. of a coupling component; X is CN, (m)ethoxy, phenoxy, aryl mercapto, aryl sulphonyl, alkyl mercapto, alkyl sulphonyl, carboxylic ester or opt. N-substd. carbonamide; Y is CN, Cl, Br, SO3H or NO2 and n = 0 or 1). Used for dyeing or printing of synthetic fibres, esp. polyesters, in reddish-violet to blue shades. Good fastness, esp. to heat, is obtd.
