Abstract

The invention relates to novel triphendioxazine pigments of formula (I)wherein X represents hydrogen or chlorine, while R1 represents phenyl substituted by one to five radicals from the group comprising C1-C4-alkyl, halogen, C1-C4-alkoxy, acetylamino, aminocarbonyl, methylaminocarbonyl and C1-C4-alkoxycarbonyl, or phenyl annelated in the 2,3- or 3,4- with a divalent radical of the formula —NH—(CO)m—NR2—, —CR2═CH—CO—NH—, —CR2═N—CO—NH—, —CO—NH—CO—NR2—, —CO—(NH)m—CO— or —O—(CO)m—NH— so as to form a five- or six-membered ring, R2 representing hydrogen, methyl, ethyl or phenyl and m representing 1 or 2.
