The present invention relates to a photopolymerizable composition comprising a polymerizable, polyethylenically unsaturated compound, benzil and/or fluorenone, a specific biphenylyl ketone such as para-phenyl benzophenone and a reducing agent such as a tertiary amine. The present composition permits rapid and complete curing. Moreover, in the photo-polymerization of compounds sensitive to air inhibition non-tacky surfaces are obtained. The effect observed is based on a synergism between the present photoinitiators.
The advantages of the invention are most manifest in curing relatively thick layers of materials.
本发明涉及一种可光聚合的组合物,该组合物包含一种可聚合的聚乙烯不饱和化合物、苯齐和/或芴酮、一种特定的联苯酮(如对苯二甲酮)和一种还原剂(如叔胺)。本组合物可以快速完全固化。此外,在对空气抑制敏感的化合物的光聚合过程中,可以获得不粘腻的表面。所观察到的效果是基于现有光引发剂之间的协同作用。
本发明的优点在固化相对较厚的材料层时最为明显。
