Provided herein are compositions useful as ink or coatings 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 and coatings having high pigment loading and existing within a conventionally-useful viscosity range.
La présente invention concerne des compositions pouvant servir d'encres ou de revêtements qui contiennent de nouveaux dispersants capables de disperser des pigments qui sont ordinairement difficiles à disperser tout en maintenant des niveaux acceptables de viscosité. L'utilisation de dispersants selon l'invention permet la préparation d'une grande variété d'encres et de revêtements présentant une charge de pigments élevée et une plage de viscosité classiquement utile.
