摘要:
The instant invention pertains to white, dyed, dipped, unscented and/or scented candle wax which is effectively stabilized against discoloration and fading by the incorporation therein of a substituted hexahydro-1,4-diazepin-5-ones in combination with a UV absorber and/or an antioxidant. Additionally, some novel substituted hexahydro-1,4-diazepin-5-one compounds are described.
摘要:
Photo-curable coating formulations which comprise a durable and/or red-shifted reactable hydroxyphenylbenzotriazole ultraviolet light absorber (UVA) are effectively photocured employing a combination of α-hydroxy ketone and bisacylphosphine oxide photoinitiators. The reactable UVA's are reacted into the coating upon curing. The combination of the photoinitiators bis(2,4,6-trimethylbenzoyl)phenylphosphine oxide and 1-hydroxycyclohexylphenylketone is especially effective for this purpose.
