Abstract:
Photo-cureable coating formulations which comprise a durable and/or red-shifted hydroxyphenylbenzotriazole ultraviolet light absorber (UVA) are effectively photocured employing a combination of α-hydroxy ketone and bisacylphosphine oxide photoinitiators. The combination of the photoinitiators bis(2,4,6-trymethylbenzoyl)phenylphosphine oxide and 1-hydroxycyclohexylphenylketone is especially effective for this purpose.
