Novel substituted diaryl ketones, photopolymerization compositions including the compounds, and methods using the same are disclosed. Polymerization of compositions which include the compounds of the invention may be activated by irradiating the composition with ultraviolet light using conventional techniques and radiation sources to give greatly improved cure speeds. The compounds of the invention also show a significantly elevated level of reactivity at a narrow wavelength band, with a peak emission wavelength at or near 308 nm. Because of the increased level of activity, the photoinitiator can be used in considerably lower amounts.
本发明涉及一种新型取代二芳基酮类化合物,包括该化合物的光聚合组合物以及使用该组合物的方法。本发明中所述的化合物可用于组成光聚合组合物,通过使用传统技术和辐射源对组合物进行紫外线照射,以大大提高固化速度。本发明中的化合物还表现出在窄波长带上具有显著提高的反应性水平,其最大发射波长接近或在308纳米左右。由于活性水平的提高,光引发剂的使用量可以大大降低。
