Abstract
A pigment-based, ink jet ink composition is disclosed which is characterized by water and accent marker resistance and by high optical density and acuity of the print. Such improvements are achieved (without loss of print quality, jetting properties, storage stability, reliability, and drying time) by adding to the ink a polymer comprised of the polymerizable half-ester of an aliphatic, nonionic surfactant, and a monomer, preferably chosen from the group of styrene, acrylic acid, and butyl acrylate.
