Novel magenta and cyan colorants for utilization within water-based inks are provided which exhibit improved chromatic properties. In particular, such colorants provide magenta or cyan colorations that exhibit increased color space characteristics, high water solubility, excellent compatability with impurities, and correspondingly cost-effectiveness for flexographic printing procedures. The methods of utilizing such colorants within flexographic printing processes are also encompassed within the invention.
La présente invention concerne des colorants magenta et cyan pour des encres à l'eau aux propriétés chromatiques améliorées. En l'occurrence, ces colorants donnent des colorations magenta et cyan faisant preuve de caractéristiques d'espace couleur accrues, d'une solubilité à l'eau élevée, d'une excellente compatibilité avec les impuretés, et par conséquent d'un bon rapport qualité-prix pour l'impression flexographique. L'invention concerne également des procédés permettant l'utilisation de tels colorants pour l'impression flexographique.
