| 摘要 |
The invention relates to novel triphendioxazine pigments of formula (I) wherein X represents hydrogen or chlorine, while R<SUP>1 </SUP>represents phenyl substituted by one to five radicals from the group comprising C<SUB>1</SUB>-C<SUB>4</SUB>-alkyl, halogen, C<SUB>1</SUB>-C<SUB>4</SUB>-alkoxy, acetylamino, aminocarbonyl, methylaminocarbonyl and C<SUB>1</SUB>-C<SUB>4</SUB>-alkoxycarbonyl, or phenyl annelated in the 2,3- or 3,4- with a divalent radical of the formula -NH-(CO)<SUB>m</SUB>-NR<SUP>2</SUP>-, -CR<SUP>2</SUP>-CH-CO-NH-, -CR<SUP>2</SUP>-N-CO-NH-, -CO-NH-CO-NR<SUP>2</SUP>-, -CO-(NH)<SUB>m</SUB>-CO- or -O-(CO)<SUB>m</SUB>-NH- so as to form a five- or six-membered ring, R<SUP>2 </SUP>representing hydrogen, methyl, ethyl or phenyl and m representing 1 or 2.
