ELECTRICALLY CONDUCTIVE PASTE AND METAL THIN FILM |
摘要 |
<p>An electrically conductive paste comprising metal microparticles, a branched polyester and an organic solvent, wherein the metal microparticles have an average particle diameter of 1 × 10-3 to 5 × 10-1 µm inclusive, the branched polyester has a branching point derived from a polycarboxylic acid compound having a functionality of three or more and/or a polyol compound having three or more functionalities, the branched polyester has an acid value of 30 to 200 equivalents/106 g inclusive, the branched polyester contains, as copolymerization components, at least one residue selected from an isophthalic acid residue, an ortho-phthalic acid residue and a cyclohexanedicarboxylic acid residue and a compound produced by substituting at least one hydrogen atom that is bound to a carbon atom contained in a linear alkyl diol having 3 to 5 carbon atoms by a linear alkyl group having 1 to 4 carbon atoms, the branched polyester has a glass transition temperature of lower than 40°C, and the metal microparticles are contained in an amount of 600 to 1500 parts by weight relative to 100 parts by weight of the branched polyester.</p> |
