Title
(EN) WATER-BASED INKS FOR INK-JET PRINTING
(FR) ENCRES A BASE D'EAU POUR IMPRESSION PAR JET D'ENCRE
Abstract
(EN)
The present invention relates to a water-based ink for ink-jet printing which not only satisfies a high optical density but also exhibits an excellent high lighter- fastness; and a water dispersion used for the water-based ink. There are provided a water dispersion for ink-jet printing containing (A) a pigment and (B) water-insoluble polymer particles produced by polymerizing an ethylenically unsaturated monomer containing 25 to 85% by weight of an aromatic group -containing monomer in the presence of a reactive surfactant; and a water-based ink containing the water dispersion.
(FR)
La présente invention se rapporte à une encre à base d'eau destinée à l'impression par jet d'encre qui présente non seulement une densité optique élevée mais aussi une excellente permanence des couleurs à la lumière. Le procédé de l’invention concerne également une dispersion aqueuse utilisée pour l'encre à base d'eau. L'invention propose une dispersion aqueuse destinée à l'impression par jet d'encre contenant (A) un pigment et (B) des particules de polymère insolubles dans l'eau produites en polymérisant un monomère éthyléniquement insaturé contenant de 25 à 85 % en masse d'un monomère comprenant un groupement aromatique en présence d'un agent de surface réactif. Elle propose également une encre à base d'eau contenant la dispersion aqueuse.
