A hardener system for a synthetic resin composition having free-radical-polymerisable compounds, which includes the following constituents: a) at least one activator in the form of a metal salt, and as free-radical starter b1) (i) at least one aldehyde and/or ketone and at least one primary amine, and/or b2) (ii) at least one aldimine or (iii) at least one ketimine, or a mixture of two or more of constituents (i) to (iii). In addition, synthetic resin compositions having such a hardener system for application especially in fixing technology, and subject matters related thereto.
