Title:
導体パターン形成用インク、導体パターンおよび配線基板
Document Type and Number:
Japanese Patent JP4911004
Kind Code:
B2
Abstract:
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; erythritol; and a polyglycerol compound having a polyglycerol skeleton. In the ink, H shown in the following formula (I) is 0.15 to 0.80; H = OH ( A ) Mw ( A ) X ( A ) + OH ( B ) Mw ( B ) X ( B ) Formula ( I ) where 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 a number of hydroxyl groups in one molecule of the erythritol, Mw(B) represents a molecular weight of the erythritol, and X(B) represents a content of the erythritol in the conductive pattern forming ink in weight percent.
