MULTILAYER OPTICAL FILM

摘要

Thermoplastic birefringent multilayer optical films are described. More particularly, thermoplastic multilayer films having alternating first and second layers having a linear layer profile where both outer layers are thinner than 350 nm but thicker than 150 nm are described. Thermoplastic birefringent multilayer optical films with thinner outer protective boundary layers are described.

1. A thermoplastic birefringent multilayer optical film comprising:
alternating first and second layers having a linear layer profile; wherein both outer layers of the thermoplastic birefringent multilayer optical film are thinner than 350 nm but thicker than 150 nm; wherein no intermediate layer is thicker than 350 nm; wherein both outer layers of the thermoplastic birefringent multilayer optical film include the same material as either the first or second layer; and wherein a minimum average delamination of the thermoplastic birefringent multilayer optical film is greater than 100 g/in.
