Abstract
Photopolymerizable compositions contain a cationically polymerizable material, such as an epoxide resin, a phenoplast, or an aminoplast, and, as photoinitiator, a diaryliodosyl salt of formula ##STR1## where R.sup.9 and R.sup.10 are the same or different and each represents a monovalent aromatic radical, PA0 x represents 1, 2, or 3, and PA0 Z.sup.x- is an anion of a protic acid. Suitable diaryliodosyl salts of formula V include diphenyliodosyl hexafluorophosphate, hexafluoroantimonate, tetrafluoroborate, toluene-p-sulfonate, and chloride. The compositions may be used as surface coatings and adhesives, and in the preparation of reinforced composites and printed circuits.
