본 발명은 산화제, 바르비투레이트로부터 유도된 광불안정성(photolabile) 환원제, 및 산화 환원 사이클에 참여하는 전이 금속 착물을 포함하는 중합 개시용 산화 환원 개시제 시스템을 제공한다. UV와 같은 화학 방사선에의 노출 시에, 광불안정성 화합물은 광분해되어 환원제를 방출하고 산화 환원-개시 중합을 개시한다. 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.
