Zusammenfassung:	Individual aqueous inks or inks in ink sets haves a non-crosslinked, crosslinkable polyurethane having an acid number of 20-40 and is derived from an aromatic diisocyanate; and a diol mixture of D1 and D2 diols, and optionally including D3 diol, D4 diol, or both D3 and D4 diols. D1 has a C3 to C7 aliphatic group and a pendant carboxy group or neutralized carboxy group. D2 has a chain of repeating C2 to C6 alkylene oxide groups. D3 is an alkoxylated bisphenol A or an aliphatic cyclic diol, present at least 5 mol %. D4 is a hydroxy-terminated polybutadiene having a molecular weight of at least 1000 and is present in an amount of 0.1-5 mol %. The ink also contains a dispersed pigment colorant; a humectant or organic co-solvent, and optionally, a crosslinking agent. These aqueous inks can be used for inkjet printing images on textiles.
