AQUEOUS INK COMPOSITION

摘要

The incorporation of a polyol redispersant, being an alcohol having at least four hydroxyl groups which are preferably underivatised, e.g. a saccharide such as sucrose, into an aqueous ink composition which comprises property- enhancing polymers (e.g. for robustness, waterfastness and adhesion) substantially enhances the redispersability of residues of the ink composition. Such use and ink compositions are described, which find particular application in continuous inkjet printing (where redispersiblity of residues is essential) and which are useful for printing on impermeable substrates whereby such ink compositions can be advantageously absent a liquid humectant.
