Abstract
An antistatic article having an antistatic layer disposed on a substrate is disclosed herein. The antistatic layer is formed from a cationic copolymer, a non-cationic (meth)acrylic polymer, and a crosslinking agent. The cationic copolymer consists essentially of a cationic monomer, a hydrophobic monomer, a crosslinkable monomer, and an optional nitrogen-containing monomer. The substrate may comprise an optical film such as a multilayer optical film. Methods for making the antistatic article and display devices containing the antistatic article are also disclosed.
