Abstract
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.
