This invention discloses a fluorene polyfunctional photoinitiator as represented by general formula (I), a photosensitive resin composition containing the same, the preparation of the same, and uses of the two. This compound has the advantages of simple synthesis, low cost, and good solubility, and has good application effects in photocurable compositions. Compared with conventional small molecule photoinitiators, it is not only excellent in photoinitiation activity, but also has the advantages such as low mobility, low odor, and yellowing resistance. The composition has high photosensitivity and good developability, high resolution, and excellent adaptation to a substrate, and is very suitable for producing a black matrix having high light-shielding property, a high-precision and high quality color filter and a liquid crystal display device, and can also be used in optical spacers and ribs, photoresist, wet film, dry film and so on.
本发明公开了一种由通式(I)表示的芴多官能团光引发剂、一种含有该化合物的光敏树脂组合物、该化合物的制备方法以及二者的用途。该化合物具有合成简单、成本低、溶解性好等优点,在光固化组合物中具有良好的应用效果。与传统的小分子光引发剂相比,它不仅具有优异的光引发活性,还具有低迁移性、低气味、耐黄变等优点。该组合物具有光敏性高、显影性好、分辨率高、对基底的适应性强等特点,非常适用于生产具有高遮光性能的黑色基体、高精度和高质量的彩色滤光片和液晶显示器件,还可用于光学垫片和肋片、光刻胶、湿膜、干膜等。
