Title:
CONDUCTIVE PASTE, DRIED FILM, INTERNAL ELECTRODE AND LAYERED CERAMIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2024/010075
Kind Code:
A1
Abstract:
Provided is a conductive paste for forming an internal electrode to be used in a layered ceramic electronic component, said conductive paste being capable of improving adhesion by suppressing a 'sheet attack' and reducing the hardness of the dried film. A conductive paste which contains a conductive metal powder, a ceramic powder, a binder resin, an additive and an organic solvent, wherein: the organic solvent contains (A) one or more types of compound selected from dihydroterpinyl acetate, isobornyl acetate, isobornyl propionate, isobornyl butyrate and isobornyl isobutyrate, and (B) one or more types of compound selected from ethylene glycol monobutyl ether acetate and dipropylene glycol methyl ether acetate; and the additive contains a phosphate polyester in an amount which is more than 0 mass% and no more than 2.0 mass% relative to the total mass of the conductive paste.
