PHOTOSENSITIVE RESIN COMPOSITION CONTAINING α-POSITION SUBSTITUTED ACRYLATE OLIGOMER AND CURED PRODUCT OF THE SAME

To provide a photosensitive resin composition containing an α-position substituted acrylate oligomer which is excellent in high heat resistance, high transparency and low curing shrinkage property.SOLUTION: A photosensitive resin composition contains a compound represented by the following formula (1), and a photopolymerization initiator. In the formula (1), R each independently represents a hydrogen atom or an alkyl group having 1 to 10 carbon atoms; X each independently represents one or more selected from the group consisting of an alkyl group having 1 to 20 carbon atoms, a cycloalkyl group having 3 to 20 carbon atoms, an aryl group having 3 to 20 carbon atoms, or an alkylene glycol group having 1 to 20 carbon atoms; and n is an average value of a repeating number, and represents a real number of 1 to 20.SELECTED DRAWING: None 【課題】本発明は、上記現状に鑑み、高耐熱性、高透明性、低硬化収縮性に優れるα位置換アクリレートオリゴマーを含有する感光性樹脂組成物を提供する。【解決手段】下記式（１）で表される化合物と光重合開始剤とを含む感光性樹脂組成物。【化１】TIFF2022042640000011.tif27153（式（１）中、Ｒはそれぞれ独立して、水素原子または炭素数１～１０のアルキル基を表す。Ｘはそれぞれ独立して炭素数１～２０のアルキル基、炭素数３～２０のシクロアルキル基、炭素数３～２０のアリール基、または炭素数１～２０のアルキレングリコール基の群から選ばれる１種以上を表す。ｎは繰り返し数の平均値であり、１～２０の実数を表す。）【選択図】なし
