    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.
