A two-component initiator system having accelerators for curing polymerizable materials comprising the following components: (a) a hydroperoxide compound containing one or more hydroperoxide groups that are bound to a tertiary carbon; (b) a thiourea derivative; and (c) as accelerator, a copper compound which is soluble in the preparation is preferably free of amine and is particularly suited for polymerizable dental compositions.
