  • Publication number: 20040147631
    Abstract: The invention relates to ink for an ink jet, said ink containing a dye which is linked to a polymer skeleton. The inventive ink is characterised in that the dye is an azomethine dye, an indoaniline dye or an azo dye; and the polymer is a copolymer consisting of at least one hydrophobic monomer and at least one hydrophilic non-ionic monomer, the molecular weight of the hydrophilic, non-ionic monomer being at least 200. Even after a long storage time, the inventive ink does not cause nozzles to be clogged and creates a printed image which is highly resistant to wiping and water and has good gloss.
