Abstract (en)

[origin: DE19743457A1] Certain anionic polyurethanes are excellently suited for use as binding agents for coating, dyeing and printing textiles and leather. Said polyurethanes are biodegradable. The residual and wash liquors left over from the dyeing process can therefore be conveyed to a biological effluent treatment plant.
