Beschreibung
Zusammenfassung:	To meet a continuing need for improved stretchable electrical conductors and flexible electrically conductive adhesives (ECAs).SOLUTION: This invention provides a polymer thick film electrically conductive paste composition comprising: conductive metal powder; a resin blend of polyol and phenoxy resin; blocked aliphatic polyisocyanate; and one or more polar, aprotic solvents. In one embodiment, the paste composition is used to form an electrically conductive adhesive. In another embodiment, the paste composition is used to form an electrically conductive polymer thick film.SELECTED DRAWING: Figure 2 【課題】改良された伸縮性電気導体及び可撓性電気導電性接着剤（ＥＣＡ）が継続的に必要とされている。【解決手段】本発明は、導電性金属粉末と、ポリオールとフェノキシ樹脂との樹脂ブレンドと、ブロック化脂肪族ポリイソシアネートと、１つ又は複数の極性、非プロトン性溶媒とを含むポリマー厚膜電気導電性ペースト組成物を提供する。一実施形態においてペースト組成物を使用して電気導電性接着剤を形成する。別の実施形態においてペースト組成物を使用して電気導電性ポリマー厚膜を形成する。【選択図】図２
