Tintenstrahldrucktinten enthaltende estermodifizierte makromolekulare Chromophore

摘要

The ink of the invention comprises a vehicle and a macromolecular chromophore colorant. The colorant is a water-insoluble pigment that has been chemically modified to be water dispersible by addition of functional groups to the surface of the pigment resulting in water dispersible colorant particles. The performance of these pigments is improved by the addition of specific functional groups which provide improved black to color bleed control and high waterfastness.
