FIELD: chemistry.
SUBSTANCE: invention relates to ink systems for jet printing, containing a fixing composition with low corrosion activity. The invention discloses a fixing composition for jet printing, containing water or a mixture of water and at least one water-miscible organic solvent, and a polycationic fixing agent whose counterion is not a halogen, where the counterion is selected such that it reduces availability of the halogen in the fixing agent. The invention also discloses a method of applying an essentially noncorrosive ink composition and a jet system for providing ink with low corrosion activity.
EFFECT: invention reduces the negative effect of the fixing agent on components of the printing head while preserving all its useful properties.
