<p><P>PROBLEM TO BE SOLVED: To provide a conductor pattern forming ink which is superior in preservation performance and prevents occurrence of cracks in a conductor pattern formed. <P>SOLUTION: The conductor pattern forming ink is an ink for forming a conductor pattern on a board by a liquid drop injection method, and contains metal particles, an aqueous dispersant in which the metal particles are dispersed, sugar alcohol of disaccharide origin, and a polyglycerol compound having polyglycerol skeleton, and H expressed in the formula (I) is 0.10-0.80. Here, in the formula, OH(A)[pieces], Mw(A), X(A)[wt.%] expresses respectively an average number of pieces of hydroxy group in a molecule of polyglycerol compound, weight average molecular weight, its content in the conductor pattern forming ink, and OH(B)[pieces], Mw(B), X(B)[wt.%] expresses respectively the number of pieces of hydroxy group in a molecule of sugar alcohol of disaccharide origin, its molecular weight, its content. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
