The invention relates to photoactive oligomeric aminoketones of general Formulae I and II, for compositions and inks curable with ultraviolet (UV) light. The oligomeric aminoketones of the general Formula I are made by condensation of aminoketones with aldehydes, and aminoketones of the general Formula II are made by acylation of aromatic amines with phthalic anhydride, followed by esterification with a polyol. The aminoketones provide good curability of energy curable coatings and inks with UV-A light, and are proposed for photoinitiator systems for low migration inks.
本发明涉及通式 I 和 II 的光活性低聚氨基酮,用于紫外线(UV)固化的组合物和油墨。通式 I 的低聚氨基酮是由氨基酮与醛缩合而成,通式 II 的氨基酮是由芳香胺与邻苯二甲酸酐酰化,然后与多元醇酯化而成。这种氨基酮类化合物在紫外线 A 光下具有良好的能量固化涂料和油墨固化性,建议用于低迁移油墨的光引发剂体系。
