    Abstract: The addition of polyisocyanates having molecular weights within the range from 364 to 4000 as crosslinking agents to aqueous pigment print pastes for textile printing consisting of (in addition to water): a) from 3 to 35% by weight, based on the ready-to-print paste, of a 15 to 55% strength aqueous dispersion of a polymer binder which under fixing conditions (100 to 200 DEG C) is film-forming and which contains as copolymerised units from 0.3 to 12% by weight, based on the polymer, of a monomer having at least one group that is reactive towards isocyanate, b) from 0.01 to 40% by weight, based on the print paste, of at least one pigment, c) from 0.1 to 8% by weight of a thickener (as solid substance) and/or from 55 to 70% by weight of naphtha (heavy benzine) in emulsified form, d) from 1 to 8% by weight, based on the print paste, of an emulsified, water-insoluble, liquid polyisocyanate, e) from 0 to 10% by weight of further additions customary in pigment printing, makes it possible to fix the prints not just with hot air, as previously, but for equally good fastness properties with steam too, expanding the range of technical options for textile printing.
