    摘要: The present invention relates to novel onium gallates or gallates of organometallic compounds and polymerizable compositions containing the same. The onium gallates include an anionic gallate moiety and a cationic moiety. The anionic gallate moiety has the formulaGaX.sub.a R.sub.b.sup.-in which X is a halogen or a hydroxy group, R is an aryl group, a and b represent integers ranging from 0 to 4 and the sum of a and b is 4. The cationic moiety is selected from the group consisting of iodonium, pyrylium, thiapyrylium, sulphonium, phosphonium, ferrocenium, and diazonium ions. The novel onium gallates are useful as cationic initiators of polymerization.
