Inkjet inks are described that have, as a principal component, a crosslinked polyurethane dispersoid binder additive. These inks can be used for printing on different media, and are particularly suitable for printing on paper.

Paper coating compositions are provided for use with thermal ink-jet color printers, such as Hewlett-Packard Company's DeskJet(R) printer.

Pigment suitable for use in coating compositions for inkjet recording media. Surfaces of an inorganic particulate are interacted with a water-soluble polyvalent metal salt in an aqueous medium. The treated particle surfaces have a significant cationic surface charge imparted to them. The salt is a salt of a metal of Group II or Group III of the Periodic Table. Inkjet recording media treated with a coating composition containing the above pigment provide high density, fast-drying, and non-feathering ink images with suitable water fastness, while the coating compositions also offer cost advantages and improved rheology at higher pigment levels over coatings based on silica pigments.
