含银组合物及银成分形成基材
摘要：
本发明提供一种含银组合物以及使用该组合物而形成的银成分形成基材，所述含银组合物含有高银含有率的丙酮二羧酸银，其在低于银盐分解温度的低温下，即使进行短时间的加热，也能够得到导电性、平坦性、贴付性优异的银成分，并且保存稳定性高。本发明的组合物的特征在于，其以特定的比例含有式(1)所示的银化合物(A)及式(2)所示的胺化合物(B)。(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)。
摘要（英）：

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): (R 1 : H, -(CY 2 )a-CH 3 , -((CH 2 )b-O-CHZc-CH 3 ; R 2 : -(CY 2 )d-CH 3 , -((CH 2 )e-O-CHZ)f-CH 3 , Y: H, -(CH 2 )g-CH 3 ; Z: H, -(CH 2 )h-CH 3 ; a: 0-8; b: 1-4; c: 1-3; d: 1-8; e: 1-4; f: 1-3; g: 1-3; h: 1-2).
