Electrographic recording materials with special compounds transporting charge carriers

Abstract

Abstract 1. An electrophotographic recording material comprising an electrically conductive base, charge carrier-producing compounds and charge carrier-transporting compounds, which contains, as charge carrier-transporting compounds, those of the formula (I) see diagramm : EP0093330,P9,F1 where R**1 and R**2 are identical or different and are each hydrogen, alkyl, allyl, benzyl or unsubstituted or substituted phenyl, or R**1 and R**2 together are see diagramm : EP0093330,P9,F2 or see diagramm : EP0093330,P9,F3 where R**5 is NR**1 R**2 , R**3 is hydrogen, alkyl, alkoxy or halogen, and R**4 is hydrogen, alkyl, alkoxy, vinyl, allyl, dialkylamino, nitro, cyano or acryloyl.
