Quinacridone pigment compositions comprising unsymmetrically substituted components

The present invention relates to a novel quinacridone pigment compositions, a process using a mixed amine synthesis for the ultimate production of the compositions and to their use as colorants for pigmenting high molecular weight organic materials.

Process for preparing pure substituted 2,5-diarylamino-terephthalates and the corresponding free acids

2,5-Diarylamino terephthalates are obtained in good yields and excellent purity when the aromatic nitro compound used for oxidizing the corresponding dihydro-2,5-diarylamino terephthalate contains the aromatic radical of said diarylamino groups, i.e. when the amine formed during the oxidation is that from which said diarylamino groups device. The products yield very pure quinacridone pigments and allow the synthesis of only one isomer of substituted quinacridones.
