Abstract

The invention relates to a kit of parts comprising Part A and Part B, Part A comprising: component(s) comprising an ascorbic acid moiety, stabilizer(s) selected from sulphite(s), phosphite(s) or mixtures thereof, optionally polymerizable component(s) without acidic moieties, optionally polymerizable component(s) with acidic moieties, and optionally filler(s), Part B comprising polymerizable component(s) without acidic moieties, polymerizable component(s) with acidic moieties, transition metal component(s), organic peroxide(s), and optionally filler(s). The invention is also directed to an initiator system comprising component(s) comprising an ascorbic acid moiety, stabilizer(s) selected from sulphite(s), phosphite(s) or mixtures thereof transition metal component(s), organic peroxide(s). The kit of parts and redox initiator system are particularly useful in the dental and orthodontic field.
