ABSTRACT:
Polymerizable compositions contain (A) a cationically polymerizable material, such as an epoxide resin, a phenoplast or a cyclic vinyl ether, (B) a hydroxy compound such as styreneallyl alcohol copolymer, and (c) an aromatic iodosyl salt of formula ##STR1## where R.sup.3 and R.sup.4, which may be the same or different, each represent a monovalent aromatic radical having from 4 to 25 carbon atoms, x denotes 1, 2 or 3, and Z.sup.x- denotes an x-valent anion of a protic acid.
Suitable salts of formula II include diphenyliodosyl hexafluorophosphate and tetrafluoroborate. The compositions may be photopolymerized or they may be thermally polymerized in the presence, as catalyst for the iodosyl salt, of a salt or complex of a d-block transition metal, a stannous salt, an organic peroxide or an activated .alpha.-hydroxy compound.
The compositions may be used as surface coatings and adhesives, and in the preparation of printing plates, printed circuits and reinforced composites.
