Benzoin derivatives which contain one or two phosphonoalkyl groups are suitable photoinitiators for the photopolymerization of unsaturated compounds, for example for curing printing inks or coatings of acrylates or unsaturated polyester resins. The new compounds can be obtained in different ways, for example by the Arbuzov reaction from the corresponding haloalkyl derivatives or by addition of esters of unsaturated phosphonic acids to benzoin or benzoin ethers.
含有一个或两个磷酸烷基基团的苯甲酸酯衍生物是适用于光引发的不饱和化合物光聚合,例如固化丙烯酸酯或不饱和聚酯树脂的印刷油墨或涂层的光引发剂。新的化合物可以通过不同的方法获得,例如通过从相应的卤代烷基衍生物的Arbuzov反应或通过将不饱和膦酸酯的酯类加到苯甲酮或苯甲酮醚中。
