Coatable compositions suitable for use in producing abrasive articles are presented. The inventive coatable compositions characterized by a combination of a free radically polymerizable composition, abrasive particles, and a photoinitiator system. The photoinitiator system characterized by a compound which cleaves via α-cleavage and has a molar absorptivity in dilute methanol solution ranging from about 4 to about 400 liter/mole-cm in at least some portion of the UV/visible spectrum ranging from about 395 and about 500 nanometers. Abrasive articles incorporating cured versions of the compositions are presented, as well as methods of making and using the articles.
本发明提出了适用于生产研磨制品的可涂覆组合物。本发明的可涂覆组合物由自由基可聚合组合物、磨料颗粒和光引发剂系统组合而成。光引发剂体系的特征是通过 α 裂解的化合物,其在稀甲醇溶液中的摩尔吸收率在约 4 到约 400 升/摩尔-厘米之间,至少在约 395 纳米到约 500 纳米的紫外线/可见光谱的某些部分具有吸收率。本文介绍了含有固化版组合物的研磨制品,以及制造和使用这些制品的方法。
