Acrylate-containing compositions are photocured by mixing at least one N-oxyazinium salt photoinitiator, a photosensitizer for the N-oxyazinium salt, an N-oxyazinium salt efficiency amplifier, an aromatic heterocyclic, nitrogen-containing base, and one or more photocurable acrylates to form a photocurable composition. This photocurable composition is then irradiated to effect polymerization of the one or more acrylates. This method can be carried out in oxygen-containing environments. |

1. A method of photocuring an acrylate-containing composition comprising:
mixing at least one N-oxyazinium salt photoinitiator, a photo sensitizer for the N-oxyazinium salt, an N-oxyazinium salt efficiency amplifier, an aromatic heterocyclic, nitrogen-containing base, one or more photocurable acrylates, and optionally, one or more inert organic solvents, to form a photocurable composition,
wherein the aromatic heterocyclic, nitrogen-containing base has a pKa of at least 10 and up to and including 22 in acetonitrile, and irradiating the photocurable composition to effect polymerization of the one or more acrylates. |
