  • Publication number: 20110124799
    Abstract: Inkjet inks that have, as principal components, a post printing curing agent and 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 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 too key wash fastness and crock testing.
