Patent

CA 2512538

Blends of monofunctional and multifunctional (meth)acrylate monomers, optionally in addition to oligomeric multifunctional (meth)acrylates), can be cured by ultraviolet radiation in contact with a photoinitiator to produce optical resinous articles having a glass transition temperature of at least 35 ~C and having physical properties making them suitable for use as microstructure-bearing articles.

L'invention concerne des mélanges contenant des monomères de (méth)acrylate monofonctionnels et multifonctionnels, éventuellement des (méth)acrylates multifonctionnels oligomériques et un photoamorceur, pouvant être durcis par rayonnement ultraviolet pour produire des articles optiques à base de résine ayant une température de transition vitreuse d'au moins 35 ·C et possédant des propriétés physiques qui permettent de les utiliser dans des articles à microstructure.
