CONDUCTIVE PATTERN FORMING INK, CONDUCTIVE PATTERN, AND WIRING SUBSTRATE

摘要

A conductive pattern forming ink for forming a conductive pattern on a substrate by a droplet discharge method includes: metal particles; an aqueous dispersion medium in which the metal particles are dispersed; xylitol; and a polyglycerol compound having a polyglycerol skeleton. H shown in the following formula (I) is 0.10 to 0.70, and $\begin{array}{cc}H=\frac{\mathrm{OH}\left(A\right)}{\mathrm{Mw}\left(A\right)}X\left(A\right)+\frac{\mathrm{OH}\left(B\right)}{\mathrm{Mw}\left(B\right)}X\left(B\right)& \mathrm{Formula}\left(I\right)\end{array}$ OH(A) represents an average number of hydroxyl groups in one molecule of the polyglycerol compound, Mw(A) represents a weight-average molecular weight of the polyglycerol compound, X(A) represents a content of the polyglycerol compound in the conductive pattern forming ink in weight percent; and OH(B) represents the number of hydroxyl groups in one molecule of the xylitol, Mw(B) represents a molecular weight of the xylitol, and X(B) represents a content of the xylitol in the conductive pattern forming ink in weight percent.
