An improved composition and a method of scavenging oxygen using said composition which comprise oxidizable organic compounds, transition metal catalysts in combination with certain photoinitiators is disclosed. The method comprises initiating scavenging by exposing the composition to UV radiation. The present composition uses certain defined benzophenone derivatives which maintain effectiveness of photoinitiation while providing reduced migration of the photoinitiator from the resin matrix.
