Provided herein are compositions useful as ink which contain novel dispersants that are capable of dispersing pigments which are traditionally difficult to disperse while maintaining acceptable levels of viscosity. Use of dispersants as taught herein enables the preparation of a wide variety of inks having high pigment loading and existing within a conventionally useful viscosity range.
Cette invention concerne des compositions convenant comme encres, contenant des nouveaux dispersants capables de disperser des pigments généralement difficiles à disperser tout en conservant des niveaux acceptables de viscosité. L'emploi de dispersant comme décrit dans cette invention permet de réaliser les encres les plus diverses à charge pigmentaire élevée dans une plage de viscosités généralement utile.
