The invention shows a photosensitive resin composition which can be used in protective film and liquid crystal display element and provides good transparency and high chemical resistance. The composition includes a complex resin (A), an o-naphthoquinone diazide sulfonate (B), and a solvent (C). The complex resin (A) includes a main chain and a side chain. The main chain includes a repeating unit derived from siloxane (meth)acrylate based monomer (a1-2). The side chain includes a repeating unit derived from siloxane based monomer (a2), and is bonded to the repeating unit derived from siloxane (meth)acrylate based monomer (a1-2). The complex resin (A) satisfies at least one of the following conditions (I) and (II):
Condition (I): the main chain further includes a repeating unit derived from unsaturated monomer (a1-1) including a carboxylic acid or a carboxylic anhydride.
Condition (II): the siloxane based monomer (a2) includes a monomer (a2-1) represented by formula (A-4).
本发明展示了一种光敏树脂组合物,可用于保护膜和液晶显示元件,具有良好的透明性和高耐化学腐蚀性。该组合物包括复合树脂(A)、邻萘醌重氮磺酸盐(B)和溶剂(C)。复合树脂(A)包括一条主链和一条侧链。主链包括由硅氧烷(甲基)丙烯酸酯单体(a1-2)衍生的重复单元。侧链包括硅氧烷基单体(a2)衍生的重复单元,并与硅氧烷(甲基)丙烯酸酯基单体(a1-2)衍生的重复单元键合。复合树脂(A)至少满足以下条件(I)和(II)之一:
条件 (I):主链还包括一个由不饱和单体(a1-1)衍生的重复单元,不饱和单体(a1-1)包括羧酸或羧酸酐。
条件(II):硅氧烷基单体(a2)包括由式(A-4)表示的单体(a2-1)。
