    摘要: Process for the bulk dyeing of synthetic linear polyesters, characterized in that one or more dyestuffs of the formula ##STR1## WHEREIN R.sub.1 and R.sub.2 denote hydrogen or a non-ionic substituent, m denotes an integer from 0 to 2 and n denotes an integer from 1 to 4 and m and n together are not greater than 4, are employed.

    摘要: Dyestuffs of the formula ##SPC1##WhereinR denotes a straight-chain or branched-chain alkyl group with 1-4 C atoms,B and B.sub.1 independently of one another denote hydrogen or optionally substituted alkyl, alkenyl, cycloalkyl, aralkyl, aryl or heteroaryl radicals or conjointly and together with the N atom form a ring which is optionally interrupted by hetero-atoms and the ring A can be substituted by 1 - 3 non-ionic substituents,Are suitable for the bulk dyeing of synthetic linear polyester.
