16. A process for forming a coating on a substrate comprising providing a coating composition comprising:
-
(A) a donor/acceptor component for forming a charge transfer complex said component being selected from the group consisting of;
(i) a bifunctional compound having an electron donor group and an electron withdrawing group and a polymerisable unsaturated group;
(ii) a mixture of (a) at least one unsaturated compound having an electron donor group and a polymerisable unsaturated moiety; and
(b) at least one unsaturated compound having an electron acceptor group and a polymerisable unsaturated group; and
