The present invention is a resin composition including (a) a resin, (b) an antioxidizing agent, and (d) a crosslinking agent, wherein the resin composition is characterized by the following: the resin (a) is formed of one or more kinds of resins selected from among polyimide precursor, polyamide, polyimide, polybenzoxazole, and copolymers thereof; and the crosslinking agent (d) includes a phenolic hydroxyl group in one molecule, and also includes a substituent group having a molecular weight of 40 or more at both ortho positions of the phenolic hydroxyl group. Provided is the resin composition by which obtained is a pattern-cured film that enables fine patterns to be obtained, that exhibits excellent in-plane pattern uniformity while being curable at a low temperature of 250° C. or less, and that retains high extensibility and high adhesion with metal wires even after a reliability evaluation which is an actual-use accelerated test.
本发明是一种树脂组合物,包括(a)树脂、(b)抗氧化剂和(d)交联剂,其中树脂组合物的特征如下:树脂 (a) 由一种或多种树脂组成,这些树脂选自聚酰亚胺前体、聚酰胺、聚酰亚胺、聚苯并恶唑及其共聚物;以及 交联剂 (d) 包括一个分子中的酚羟基,还包括在酚羟基的两个正交位置上分子量大于或等于 40 的取代基。本发明提供了一种树脂组合物,通过该树脂组合物获得的图案固化膜可以获得精细的图案,在 250°C 或更低的低温下固化,同时表现出优异的面内图案均匀性,即使在经过实际使用加速试验的可靠性评估后,仍能保持高延伸性和与金属丝的高粘合性。
