The present invention provides a resin composition having a high sensitivity and serving to produce a cured film with a low water absorption rate. The resin composition includes: (a) an alkali-soluble resin and (b1) an amido-phenol compound containing a phenolic hydroxyl group in which a monovalent group as represented by the undermentioned general formula (1) is located at the ortho position and/or (b2) an aromatic amido acid compound containing a carboxy group in which a monovalent group as represented by the undermentioned general formula (2) is located at the ortho position:
wherein in general formula (1), X is a monovalent organic group having an alkyl group that contains 2 to 20 carbon atoms and bonds directly to the carbonyl carbon in general formula (1) or a monovalent organic group that has —(YO)
n
—; and in general formula (2), U is a monovalent organic group that has an alkyl group containing 2 to 20 carbon atoms and bonding directly to the amide nitrogen in general formula (2) or a monovalent organic group that has —(YO)
n
—; wherein Y is an alkylene group containing 1 to 10 carbon atoms and n is an integer of 1 to 20.
本发明提供了一种树脂组合物,具有高灵敏度,并用于生产具有低吸水率的固化膜。该树脂组合物包括:(a)可溶于碱的树脂和(b1)含有酚羟基的酰胺酚化合物,其中酚羟基化合物中的单价基在邻位上,和/或(b2)含有羧基的芳香酰胺酸化合物,其中羧基化合物中的单价基在邻位上,其通式如下所示:在通式(1)中,X是一个单价有机基,具有含有2到20个碳原子的烷基,并直接连接到通式(1)中的羰基碳,或具有—(YO)n—的单价有机基;在通式(2)中,U是一个单价有机基,具有含有2到20个碳原子的烷基,并直接连接到通式(2)中的酰胺氮,或具有—(YO)n—的单价有机基;其中Y是含有1到10个碳原子的烷基,n是1到20的整数。
