Abstract
The present disclosure provides a redox initiator system for initiating polymerization comprising an oxidizing agent, a photolabile reducing agent derived from a barbiturate, and a transition metal complex that participates in a redox cycle. On exposure to actinic radiation, such as UV, the photolabile compound photolyzes, releasing the reducing agent and initiating the redox-initiated polymerization.
