  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）。
