An ink jet ink for textile printing contains a reactive dye, where 1.2% by mass or more and 2.3% by mass or less of C.I. Reactive Blue 49 based on the total amount of the ink is contained as the reactive dye.

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.
