また、重合度の大きい(分子量の大きい)(A)成分を得るには、上記亜りん酸エステル、ピリジン誘導体、有機溶媒の他に、塩化リチウム、塩化カルシウムなどの無機塩類を併用して重縮合することが好ましい。

硬化促進剤を併用する場合の含有量は、(B)成分100質量部に対して通常10質量部以下、好ましくは0.1乃至5.0質量部である。
併用し得るできる導電性粒子としては、銀、金、銅、アルミニウム、ニッケル、白金、パラジウムなどの金属粒子や、銅粒子に銀をコーティングした銀コート銅の粒子、及び前記列挙した金属を含む合金粒子などが挙げられるがこれらに限定されるものではなく、使用態様により適宜選択することができる。
導電性粒子を併用する場合の含有量は、本発明の樹脂組成物の固形分対して通常95質量以下、好ましくは70乃至95質量%、より好ましくは80乃至90質量%である。導電性粒子の含有量を70質量%以上とすることで、形成される導電材料の電気抵抗率を低くすることができると考えられる。また、95質量%以下とすることで、導電性ペーストの接着力を確保し、形成される導電材料の割れを抑制することができると考えられる。
本発明の樹脂組成物を有機溶剤に溶解したワニスとし、基材に該ワニスを塗布した後に有機溶剤を乾燥してフィルム化することにより、本発明の接着フィルムとすることができる。
