  • Digital textile printing inks having zero volatile organic compound solvents therein
    Patent number: 11413896
    Abstract: An ink, having a viscosity of 2.5 to 15 centipoise at 25° C., for textile printing includes pigment; a water dispersible anionic polymeric resin; a water soluble zero volatile organic compound solvent with a boiling point of 250° C. or greater; a crosslinking agent; and water. The water dispersible polymeric resin has particles with a median volume weighted size of less than 150 nm and a 95th percentile volume weighted size of less than 250 nm. The water dispersible polymeric resin has an acid number value of 5 to 40, a resin film elongation of 500 to 1200%, and a film tensile strength of 10 to 60 mPa.
    Type: Grant
