The photopolymerization activity has been checked. It is shown that addition of ITX to BP-SK/AH clearly enhances the efficiency of the photopolymerization of clear or pigmented coatings. This is explained (although, a direct interaction between the triplet state of ITX and BP-SK occurs to some extents) on the basis of the interaction of BP-SK with the ketyl radical of ITX. © 2000 John Wiley & Sons, Inc.
