1,4,5-TRIAMINO-8-HYDROXY ANTHRAQUINONE DYESTUFFS FOR POLYESTERS AND POLYAMIDES CONTAINING SUBSTITUTED 2 AND/OR 3 POSITIONS WHEREIN ONE OF SAID POSITIONS CONTAINS A SUBSTITUENT SELECTED FROM THE GROUP CONSISTING OF SUBSTITUTED OR UNSUBSTITUTED ALKYL, ARYL, AND ARALKYL GROUPS LINKED TO THE ANTHROQUINONE NUCLEUS THROUGH A BRIDGE SELECTED FROM THE GROUP CONSISTING OF O, S, SO, AND SO2, ARE PREPARED BY REACTING A CYCLIC SULFAMIDE OR CYCLIC SULFIMIDE ESTER WITH SULPHUR IN OLEUM.
摘要:
The invention comprises dyes of formula wherein A is an anthraquinone radical which may be further substituted by a substituent which does not increase water-solubility and which preferably contains up to 4 condensed rings, R is H or CH3 and n is 1 or 2. The dyes are prepared by (a) condensing an aminoanthraquinone with an optionally methyl-substituted N - 3 - tetramethylene - sulphone - carbamic acid chloride or -isocyanate or (b) condensing an N-anthraquinonyl-carbamic acid chloride or -urethane with an optionally methyl -substituted 3 - amino - tetramethylene-sulphone. The dyes are used to colour synthetic fibre materials such as polyamides, polyurethane, polyacrylonitrile, polyester or cellulose ester fibres in yellow, orange, red and blue shades.
摘要:
The process for the continuous dyeing of synthetic fiber materials in which the fiber materials are impregnated with a dyeing liquor comprising an organic solvent and an anthraquinone dyestuff of formula
IN WHICH B and B'' independently of one another represent a C1C9- alkyl, cycloalkyl or aralkyl radical, Ha1 and Ha1'' denote a halogen atom, each of m and n is a number from 0-3, with the proviso that the sum of m+n is at least 1, and each of p and q is a number from 0-2; and the dyed materials are subsequently subjected to a heat treatment. The dyeings obtained are distinguished by high dyestuff yield, very good buildup and excellent fastness properties, especially very good fastness to thermofixing, washing, rubbing and light.
