Date Mar. 21, 1996Mono-N-alkyl-quinacridone pigments are disclosed. They exhibit high light fastness, high temperature stability and high migration fastness. Moreover, they show hypsochromic shifts, fluorescence and high photoconductivity. These pigments are suited for coloring high molecular weight organic materials, for use as light emitting materials of organic electroluminescent elements as well as photoreceptors of electrophotography.
