Abstract

The effectiveness of redox buffers in discharge printing processes for synthetic textile fibres using nitrobenzoic acids, nitrohydroxybenzenesulphonic acids or -carboxylic acids as such redox buffers is raised by the additional use of metal salts of various oxidation states and complexing agents and/or nonionic polyglycol ethers as dispersants.
