| abstract |
The present invention relates to aqueous, pigment-based ink compositions for use in ink jet printers. These compositions comprise a carrier medium, an insoluble pigment, and a polymer produced by reacting a mixture of styrene, acrylic acid, and butyl acrylate in a polymerization reaction. The ink compositions are characterized by their water resistance and accent marker resistance properties, while also achieving excellent print quality, jetting properties, storage stability, reliability, and dying times. |
