example 1

[0048] Example 1 prepared 12% by weight sulfopolyester C, 3.6% by weight CYMEL 301 (30% by weight relative to sulfopolyester solids), 0.05% by weight ), and an aqueous solution composed of 0.15% by weight of TOMADOL 25-9, wherein all weight ratios outside the brackets are relative to the total amount of the aqueous solution. The mixing sequence is as follows: water, surfactant, binder, crosslinker and catalyst. Mix the solution thoroughly after each addition of a substance.

[0049] The solution was coated onto a cast polyester multilayer optical film using a #3 wire wound rod. After coating was completed, the film was dried at 80° C. for 2 minutes. Multilayer optical films were prepared as described in US 2001 / 0013668 (Neavin et al.). Then, the coated multilayer optical film was preheated at 160° C., and then stretched at a constant rate of 50% / sec at a transverse stretch ratio of 6.5:1.

Abstract

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.

Description

technical field [0001] This invention relates to coatings for optical films, and more particularly, to primer layers for multilayer optical films. Background technique [0002] In the field of polymer films, the problem is often encountered that it is difficult to provide strong adhesion between a substrate and a functional coating applied thereto. This is particularly the case with polyester-based substrates. To solve this problem, a primer layer or coating is usually applied to the polyester substrate to improve the adhesion between the substrate and the functional coating. Especially difficult adhesion problems are often encountered during the manufacture of optical films having a microstructured surface layer disposed on a multilayer optical film. The microstructured surface layer is formed by coating a UV-curable acrylic resin onto a multilayer optical film and then curing the resin by pressing it against a microstructured roll. Contents of the invention [0003] D...
