Abstract
Official abstract text for this publication.
This disclosure relates to novel aqueous ink-jet inks having improved jetting properties containing an aqueous vehicle, a colorant, and a mixture of a dispersible crosslinked polyurethane binder and one or more soluble anionic polymeric binders.
First claim
Opening claim text (preview).
What is claimed is: 1 . An ink-jet ink comprising an aqueous vehicle, a colorant, a first polymer and a second polymer; wherein said colorant is self-dispersed or dispersed by a dispersant, said first polymer is a crosslinked polyurethane and is dispersible in said aqueous vehicle, and said second polymer is an anionic polymer soluble in said aqueous vehicle and is one or more members selected from the group consisting of acrylic, polyurethane, hydrolyzed styrene maleic anhydride (SMA) and styrene acrylic acid polymer (SA), and wherein said first polymer and said second polymer are different from said dispersant. 2 . The ink of claim 1 , wherein said colorant is dispersed by a dispersant. 3 . The ink of claim 2 , wherein said second polymer is polyurethane. 4 . The ink of claim 3 , wherein said dispersant is crosslinked. 5 . The ink of claim 3 , wherein said ink is printed on an offset media. 6 . The ink of claim 3 , wherein said ink is printed on textile. 7 . The ink of claim 2 , wherein said second polymer is acrylic. 8 . The ink of claim 7 , wherein said dispersant is crosslinked. 9 . The ink of claim 7 , wherein said ink is printed on an offset media. 10 . The ink of claim 7 , wherein said ink is printed on textile. 11 . The ink of claim 1 , wherein said colorant is self-dispersed. 12 . The ink of claim 11 , wherein said second polymer is polyurethane. 13 . The ink of claim 12 , wherein said ink is printed on an offset media. 14 . The ink of claim 12 , wherein said ink is printed on textile. 15 . The ink of claim 11 , wherein said second polymer is acrylic. 16 . The ink of claim 15 , wherein said ink is printed on an offset media. 17 . The ink of claim 15 , wherein said ink is printed on textile. 18 . An ink-jet ink consisting of an aqueous vehicle, a colorant, a first polymer and a second polymer; wherein said colorant is self-dispersed or dispersed by a dispersant, said first polymer is a crosslinked polyurethane and is dispersible in said aqueous vehicle, and said second polymer is an anionic polymer soluble in said aqueous vehicle and is one or more members selected from the group consisting of acrylic, polyurethane, hydrolyzed styrene maleic anhydride (SMA) and styrene acrylic acid polymer (SA), and wherein said first polymer and said second polymer are different from said dispersant.
