Abstract
The present invention relates to the use of reactive colourless and metal-free protein cross-linking agents for the cross-linking (tanning) of protein-containing substrates, said agents are environmentally friendly and give an improved fixation yield, a long-term cross-linking (tanning) stability and good washing off properties. The present invention further relates to processes for the cross-linking (tanning) of protein-containing substrates thereby creating an environmentally friendly process which minimizes the use of chemicals and further improves the quality and efficiency of the tanning and dyeing process.
