Definitions

  • the inkjet printing process is usually carried out using aqueous inks, which are sprayed as small droplets directly onto the substrate.
  • aqueous inks which are sprayed as small droplets directly onto the substrate.
  • There is a continuous form of the process in which the ink is pressed piezoelectrically through a nozzle at a uniform rate and deflected onto the substrate by an electric field, depending on the pattern to be produced, and there is an uninterrupted inkjet or drop-on-demand process, in which the ink is expelled only where a colored dot is to appear.
  • the latter form of the process employs either a piezoelectric crystal or a heated cannula (bubble or thermal jet process) to exert pressure on the ink system and so eject an ink droplet.
  • EP-A 0 886 000 and EP-A 0 885 998, EP 0 620 116, EP-A 0 606 777, DE-A 4417718, DE-A 4417719 describe dye inks containing fiber-reactive dyes. These dye inks have some application weaknesses, for example unsatisfactory dye ink stability or low dye yield owing to insufficient interaction of the dyes from the ink with the fiber.
  • the European patent specification EP-A 0 602 885 describes sulfolane-containing dye inks for the nontextile area which are not suitable for textile application. Consequently, there is a demand for novel printing inks for the inkjet process with fiber-reactive dyes that have improved properties, especially application properties.
