Title (EN) WATER-BASED PIGMENTED INKS
(FR) ENCRES PIGMENTEES A BASE AQUEUSE
Abstract:
(EN) Water-based pigmented inks are disclosed. Such inks are formed from water-based dispersions of pigment particles having novel dispersants therein. The dispersions are formed from the reaction product of an alkenyl azlactone with an N-substituted amino acid compound. Subsequent to the reaction, the reaction product is ring-opened using an amine and, optionally, hydrolyzed. The resulting inks are well-suited for use in ink jet and other printing applications.
(FR) L'invention concerne des encres pigmentées à base aqueuse. Ces encres sont préparées à partir de dispersions aqueuses de particules de pigment contenant de nouveaux dispersants. Ces dispersions sont constituées à partir du produit réactionnel d'un azlactone d'alcényle avec un composé amino acide N-substitué. Consécutivement à la réaction, le noyau du produit réactionnel est ouvert au moyen d'une amine et, éventuellement, hydrolysé. Les encres obtenues se prêtent à une utilisation dans des imprimantes à jet d'encre et dans d'autres domaines de l'imprimerie.
