Patent ID: 10017655

Abstract:
Provided are a silver element containing silver acetonedicarboxylate with high silver content, and capable of providing a silver element with excellent electrical conductivity, flatness, and adhesivity through heating even for a short time at a low temperature of below the decomposition temperature of the silver salt, and having excellent storage stability, as well as a substrate having a silver element formed thereon with the composition. The composition is characterized by a particular ratio of silver compound (A) represented by formula (1) and amine compound (B) represented by formula (2): (R1: H, —(CY2)a-CH3, —((CH2)b-O—CHZ)c-CH3; R2: —(CY2)d-CH3, —((CH2)e-O—CHZ)f-CH3, Y: H, —(CH2)g-CH3; Z: H, —(CH2)h-CH3; a: 0-8; b: 1-4; c: 1-3; d: 1-8; e: 1-4; f: 1-3; g: 1-3; h: 1-2).
