Abstract
Abstract New diaryliodosyl salts have the formula ##STR1## where R 7 and R 8 , which may be the same or different, each represent a monovalent aromatic radical of from 6 to 22 carbon atoms, Z t- denotes a t-valent anion of formula MX n - or R 9 SO 3 - or a t-valent anion of a halogen-free inorganic oxy acid, t is 1, 2 or 3, M represents an atom of a metal or metalloid, X denotes a halogen atom, preferably of fluorine or chlorine, n is 4, 5, or 6 and is one more than the valency of M, with the proviso that MX n - can represent SbOHF 5 - , and R 9 denotes a monovalent aliphatic or aromatic group of 1 to 20 carbon atoms. These salts have utility as photocuring catalysts for cationically polymerizable materials such as epoxide resins and phenolic resins.
