ABSTRACT:
Substances (I) capable of being converted into higher-molecular weight materials under the influence of a cationic catalyst, such as 1,2-epoxides, aminoplasts, vinyl monomers or prepolymers, or phenoplasts, are so converted by exposure to actinic radiation in the presence of a sulphoxonium salt (II) of formula ##STR1## where P denotes zero or 1,
