摘要：
Novel blends of photo-initiators and photo-absorbers are disclosed. By the proper selection of the type and amount of absorber and initiator used in a composition, it is possible to regulate the conditions under which photo-induced reactions occur. In a specific embodiment, blends of UV initiators and photoabsorbers are used to control the conditions under which UV initiated polymerization occurs.
