Problems solved by technology

However, increasing the fluorine content of the fluoropolymer coating reduces the surface energy of the coating, which in turn reduces the bond between the fluoropolymer layer and other polymer layers or the substrate layer (to which the fluoropolymer layer is attached). interfacial adhesion

Abstract

An economic, optically transmissive, stain and ink repellent, durable low refractive index fluoropolymer composition for use in an antireflection film or coupled to an optical display. In one aspect of the invention, the composition is formed from the reaction product of a fluoropolymer or reactive fluoropolymer, an amino silane ester coupling agent or ester equivalent, a multi-olefinic crosslinker, and optional surface modified inorganic particles or sol gel precursors.

Description

[0001] Technical field and industrial applicability [0002] The present invention relates to an anti-reflection film, and more specifically, the present invention relates to a low refractive index fluoropolymer coating composition for an anti-reflection polymer film. Background technique [0003] In the display industry, anti-reflective polymer films ("AR films") are becoming increasingly important. People are developing new applications for low-refractive-index films that are coated on the substrates of products used in computers, televisions, appliances, mobile phones, aerospace, and automotive industries. [0004] In order to reduce the amount of light reflected by the surface of the optical display, AR films are usually constructed by alternating high refractive index ("RI") and low refractive index polymer layers. In AR films used on optical articles, the desired product is characterized by a low percentage of reflected light (for example, 1.5% or less) and resistance to scra...
