ABSTRACT:
The present invention relates to a method for textile printing with aqueous dispersions in which an organic fixing agent is crosslinked with a blocked polyisocyanate having (i) an average molecular weight of about 800 to about 25,000, (ii) a content of blocked isocyanate groups, calculated as free NCO and based on non-blocked polyisocyanate, corresponding to an NCO content of about 5 to about 20% by weight, (iii) an ionic group content of about 1 to about 75 milliequivalents per 100 g of blocked polyisocyanate, and (iv) a content of polyalkylene oxide units of about 1 to about 20% by weight, based on blocked polyisocyanate, said blocked polyisocyanate being obtained by the reaction of
