Abstract

Different phthalocyanine dye ink formulations were prepared. They were inkjet printed and tested for suitability as insulating or dielectric layers for printed electronics. In the process of ink making, Z number, a combination measure of specific gravity, surface tension and viscosity was used to predict jettability. Ink formulations are considered to be suitable for ink jetting when the Z number is in the range 2?Z?14. In order to make the Z number in this range, isopropyl alcohol (IPA), ethylene glycol (EG), acrylic ink jet resins (Joncryl 678, Joncryl 682) and surfactant (Carbowet 300, Air Products) were used in the ink formulations with the aim to adjust the surface tension, viscosity and abrasion resistance [Yumeizhi, 2013].
