Abstract (en)

[origin: EP0624474A2] A printing head for use in ink jet printing comprising an ink-jetting nozzle and an ink channel connected to the ink-jetting nozzle, at least a part of the ink channel comprising an activation-energy-ray- hardening resin is disclosed. The resin in the printing head has a certain hardened state. The printing head has improved resistance to ink compositions containing acetylene glycol which sometimes damage the conventional printing heads comprising an activation-energy-ray-hardening resin.
