Document Type and Number:
WIPO Patent Application WO/2018/180048
Kind Code:
A1
Abstract:
[Problem] To provide an electroconductive paste which is useful especially for the internal electrodes of multilayered ceramic capacitors, has low viscosity suitable for gravure printing, and gives films that are inhibited from suffering reaggregation of the electroconductive metal powder and are less apt to suffer a deformation or separation, after printing or during storage after production.
[Solution] An electroconductive paste for the internal electrodes of multilayered ceramic capacitors which comprises an electroconductive powder (A), an organic resin (B), an organic solvent (C), an additive (D), and a dielectric powder (E), wherein the organic resin (B) consists only of ethyl cellulose, the organic solvent (C) consists only of terpineol, and the additive (D) comprises a composition comprising an unsaturated carboxylic acid dispersant and an oleylamine dispersant, the content of the unsaturated carboxylic acid dispersant in the additive (D) being 0.2-1.2 mass% with respect to the whole electroconductive paste and the content of the oleylamine dispersant being 0.3-2.0 mass%.
