Curable compositions containing metallocene complexes, the activated precursors obtainable therefrom and the use thereof The present invention provides activated curable compositions obtainable by irradiating a curable composition which comprises A) a cationically polymerisable organic material and B) at least one compound of the formula I ¢(R1) (R2M)a! +an ? ¢LQm!-q (I) wherein a is 1 or 2, each of n and q independently of the other is an integer from 1 to 3, M is the cation of a monovalent to trivalent metal of groups IVb to VIIb, VIII or Ib of the Periodic Table, m is an integer corresponding to the valency of L + q, Q is a halogen atom, L is a divalent to heptavalent metal or non-metal, R1 is a -arene and R2 is a -arene or the anion of a arene, at a temperature which is below that employed for the subsequent heat curing. These compositions are suitable for the production of surface coatings, printing plates and in particular, printed circuits. The curable compositions comprising (A) and (B) as defined above may be heat-cured direct, but are preferably first irradiated to give storage stable activated precursors and then heat-cured. |
