Abstract
Inks for ink jet printers contain an aqueous carrier medium; a colorant that is insoluble in the aqueous carrier, a polymer dispersant; and a linear polymer additive selected from the group consisting of an water soluble, elastomeric ABA block polymer comprising an elastomeric B block and non-elastomeric A blocks; anionic polymers selected from neutralized acrylic and methacrylic acid polymers; cationic polymers selected from neutralized or quaternized amine polymers; water-dispersible .beta.-diketone containing polymers and ethylene oxide containing polymers.
