    摘要: Cationically polymerizable compounds, for example epoxide compounds, can be polymerized photochemically using a catalyst combination consisting of an aromatic iodonium salt and a ketone of the formula I, II or III ##STR1## in which n is 1 or 2 and Ar, X, X', R.sup.1, R.sup.2 and R.sup.3 are as defined in claim 1. In this combination, the ketones act as a co-catalyst and drastically accelerate the photopolymerization, although they are not able to initiate a cationic photopolymerization on their own.

    摘要: 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.
