OPTICAL ARTICLE HAVING ANTISTATIC HARDCOAT LAYER

摘要

Disclosed herein is an optical article that may be used to protect the exposed viewing surface of a display device. The optical article comprises: a light transmissive substrate; and a hardcoat layer disposed on the light transmissive substrate, the hardcoat layer comprising: a (meth)acrylate-functionalized metal oxide having an average particle size of less than about 100 nm, a multifunctional (meth)acrylate monomer, and a cationic copolymer comprising from about 25 to about 60 wt.% of a cationic monomer comprising a quaternary amine group, about 5 to 30 wt.% of a tertiary amine monomer comprising a tertiary amine group, and about 10 to 60 wt.% of a hydrophobic monomer comprising an alkyl group having from 4 to 12 carbon atoms.
