The present invention provides a polyimide resin, a resin composition, an adhesive solution, a film-state joining component, and an adhesive laminate film soluble in a solvent having excellent heat resistance and adhesion, capable of bonding and curing at relatively low temperatures. Specifically, the present invention provides a novel polyimide resin having low water absorption obtained by a reaction between tetracarboxylic acid dianhydride containing ester-acid dianhydride represented by the general formula (1):
wherein X represents -(CH2)k-, or is a divalent group which comprises an aromatic ring, and k is an integer from 1 to 10; and aromatic diamine, where the resin composition and the film-state joining component which comprise a thermosetting resin with excellent adhesion using this resin are preferably used for flexible printed circuit boards, tapes for TAB (Tape Automated Bonding), composite lead frames, and lamination materials, or the like, and an adhesive laminate film suitable for coating of a superconductive wire rod.
本发明提供了一种可溶于溶剂的聚酰亚胺树脂、树脂组合物、粘合剂溶液、膜态接合成分和粘合层压膜,具有优异的耐热性和粘合性,能够在相对较低的温度下粘合和固化。具体地说,本发明提供了一种吸水性低的新型聚酰亚胺树脂,它是由含有通式 (1) 所代表的酯酸二酐的四羧酸二酐反应得到的:
其中 X 代表-(CH2)k-,或者是由芳香环组成的二价基团,k 是 1 至 10 的整数;和芳香二胺,其中树脂组合物和薄膜状态连接组分由具有优异粘合性的热固性树脂组成,使用这种树脂最好用于柔性印刷电路板、TAB(胶带自动粘合)用胶带、复合引线框架和层压材料或类似材料,以及适用于涂覆超导线棒的粘合层压薄膜。
