<P>PROBLEM TO BE SOLVED: To obtain improved pigment-based ink compositions capable of satisfying simultaneously the properties required of an ink composition for inkjet printing, especially properties of (a) high performance printing of text or graphics on a substrate, (b) short dry time of the ink on the substrate, (c) good jetting properties, (d) resistance of the ink after drying on the substrate to water and to accent markers, (e) long-term storage stability and (f) long-term reliability, and to obtain a polymer that provides an ink composition for inkjet printing with reduced water sensitivity and obtain a polymer that provides an ink composition for inkjet printing with reduced accent market sensitivity. <P>SOLUTION: This inkjet ink comprise a carrier medium, an insoluble pigment, and a polymer produced by polymerizing at least one ethylenically unsaturated monomer with at least one glycol ester monomer. <P>COPYRIGHT: (C)2003,JPO |
