Abstract: Process for dyeing and printing textile material with vat or sulfur dyes using reductones or reductonates at pH about 12 or more in the presence of a quinoid compound which is soluble in water in the said pH range, and dye formulations which contain reductones or reductonates as reducing agents. The reducing agents are resistant to atmospheric oxygen and do not cause any overreduction in the case of sensitive dyes.
Abstract translation: 使用还原剂或硫化染料染色和印刷纺织材料的方法，在pH约为12或更高的pH下，在可溶于所述pH范围的水中的醌型化合物存在下，以及含有还原剂或还原剂的染料配方作为还原剂 代理商 还原剂对大气氧具有抗性，并且在敏感染料的情况下不会引起任何过度还原。
