INK JET INK WITH HIGH STRUCTURE PIGMENT PARTICLES

摘要

An ink jet ink with high structure pigment particles can include a liquid vehicle, high structure pigment particles dispersed in the liquid vehicle at from about 0.2 wt % to about 5.0 wt %, and a polyurethane binder present in the liquid vehicle at from about 0.2 wt % to about 5.0 wt %. The high structure pigment particles can have polymer dispersant adsorbed onto a surface thereof, a DBP absorption value at a minimum of about 75 ml/100 g, and a surface area of about 200 m2/g to about 2000 m2/g.
