IN WHICH Ar, Hal and n have the meaning given below in the disclosure. By means of these dyestuffs there are obtained dyeings in excellent dyestuff yields and fastness properties.
Exhaust process for the dyeing of synthetic fibre materials from organic water-immiscible solvents wherein are used as dyestuffs anthraquinone dyestuffs of the formula
摘要:
This application relates to the synthesis of compounds having the formula:
WHEREIN EACH X is hydroxy or amino (including secondary amino, e.g., alkylamino), and R is an alkylene radical, preferably a lower alkylene radical containing 1-6 carbon atoms; and to compounds having the formula: WHEREIN R is the same as above; as well as to the use of such compounds in photographic developer compositions and developing processes. The compounds of formula (A) are also suitable for use as dyes for textile fibers.
