|1. (WO2018042635) ELECTROCONDUCTIVE LIQUID COMPOSITION|
|Applicants:||TEIKOKU PRINTING INKS MFG. CO., LTD
|Title:||ELECTROCONDUCTIVE LIQUID COMPOSITION|
The present invention provides an electroconductive liquid composition that can be used for a plastic film substrate etc., the electroconductive liquid composition comprising, each in a specific range, (A) a hydroxyl group-containing resin, serving as a binder resin, having a hydroxyl value of 3-100 and a weight average molecular weight of 4000-20000, (B) a solvent having a boiling point of 170°C or higher, serving as a solvent, (C) polyisocyanate serving as a curing agent, (D) an organometal compound serving as a curing promotor, (E) a coupling agent serving as an adhesion reinforcing agent, and (F), as an electroconductive material, (f1) graphite, (f2) electroconductive carbon black, and (f3) sliver-coated silica particles having an average particle size of 1.0-7.0 µm, wherein (G) the surface resistivity of a cured film of the electroconductive liquid composition, when the thickness of said cured film is 8 µm, is 1-1000 Ω/sq. Thereby, the present invention provides an electroconductive liquid composition that exhibits sufficient electroconductive functions even with a thin film thickness, has such surface smoothness that no fine irregularities are formed when applied as a coating and uniform electroconductive functions are exhibited, and endures cleaning with MEK etc.
