<p>Mono-N-alkyl-quinacridone pigments are disclosed. They exhibit high lightfastness, 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.</p> |
