Title:
ELECTROCONDUCTIVE INK
Document Type and Number:
WIPO Patent Application WO/2007/108188
Kind Code:
A1
Abstract:
This invention provides an electroconductive ink comprising metallic fine
particles and a solvent. A screen printing method for printing the above electroconductive
ink utilizing a screen printing technique is known as a method for forming an electroconductive
circuit pattern on various substrates. In the screen printing method, however,
since the formation of a fine circuit pattern is difficult, a method for printing
the above electroconductive ink by an ink jet method has recently been proposed
as a method for directly forming a fine circuit pattern. A print pattern formed
by the ink jet method suffers from, for example, a problem of unsatisfactory adhesion
to various substrates. The above problem can be solved, for example, by incorporating
a Ti- or Al-containing coupling agent or an inorganic binder of a chelate in the
above electroconductive ink.
