Abstract
A hardenable composition containing: PA1 a) a material polymerizable by free radical or cationic polymerization, PA1 b) at least one iron compound of the formula I ##EQU1## wherein a is 1 or 2 and q is 1, 2 or 3, PA1 L is a divalent to heptavalent metal or non-metal, PA1 Q is a halogen atom, PA1 m is an integer corresponding to the sum of the values of L and q, PA1 R.sup.1 is an unsubstituted or substituted .eta..sup.6 -benzene and PA1 R.sup.2 is an unsubstituted or substituted cyclopentadienyl anion, and PA1 c) at least one sensitizer for the compound of the formula I, PA1 and, in the case of materials polymerizable by free radical polymerization, also d) an electron acceptor as an oxidizing agent, which is also advantageously used concomitantly for the material polymerizable by cationic polymerization. The composition is suitable for the production of protective layers and photographic images.
