Abstract
Official abstract text for this publication.
Disclosed herein is an optical article including a multilayer optical film and a primer layer disposed on the multilayer optical film. The primer layer consists essentially of a sulfopolyester and a crosslinker. The multilayer optical film may be a reflective film, a polarizer film, a reflective polarizer film, a diffuse blend reflective polarizer film, a diffuser film, a brightness enhancing film, a turning film, a mirror film, or a combination thereof. A microstructured or unstructured optical layer may be disposed on the primer layer opposite the multilayer optical film. Also disclosed herein is a method of making the optical article. Also disclosed herein is a display device including the optical article.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical article comprising: a multilayer optical film, and a primer layer disposed on the multilayer optical film, the primer layer consisting of a sulfopolyester, a melamine-formaldehyde crosslinker, a catalyst and a surfactant, wherein the ratio of sulfopolyester to crosslinker is from about 1:1 to about 20:1. 2. The optical article of claim 1 , the sulfopolyester comprising a water soluble sulfopolyester or a water dispersible…
