Abstract:
Light-collimating films as well as other microstructured film articles are described that comprise a (e.g. UV) cured light transmissive film comprising the reaction product of a polymerizable resin composition. Polymerizable resin compositions are also described that comprise aliphatic urethane (meth)acrylate oligomer(s), bisphenol-A ethoxylated diacrylate(s), and a crosslinker having at least three (meth)acrylate groups.
