Abstract
Inkjet inks that have, as a principal component, a crosslinked polyurethane dispersoid binder additive with selected diols used to prepare the polyurethane. The diols include a polyether diol, an ionic diol and polycarbonate, polyamide and/or poly(meth)acrylate diols. These inks can be used for printing on different media, and are particularly suitable for printing on textiles. The printed textiles are particularly durable to wash fastness and crock.
