A number of studies have been carried out to investigate the photo-oxidation and which occur in various multifunctional acrylated systems . The complex formulations of radiation curable resins complicate our understanding of the mechanisms involved. For example, high concentrations of photoinitiators in UV curable resins will often dominate the subsequent photo reactions and contribute significantly to photoyellowing.

In this paper, we have examined the postcured photoyellowing and properties of a number of different dialkylamine terminated diacrylate resins prepared via a Michael reaction of the corresponding secondary amine with a trifunctional monomer Photomer 4094, and compared the results with our standard amine synergist Photomer 4116.
