Antistatic article, method of making the same, and display device having the same

An article comprising:

• A) a substrate;
• and
• B) an antistatic layer disposed on the substrate, the antistatic layer comprising:
• a) a cationic copolymer consisting essentially of:
• i) from about 20 to less than 70 wt % of a cationic monomer having the formula:
• CH2═CR1COZ(CH2)nN(R2)3X
• wherein
• Z is O, S, or NH;
• R1 is H or CH3;
• R2 independently comprises an alkyl group having from 1 to 4 carbon atoms;
• X is an anion selected from the group consisting of halogen, nitrate, alkylsulfate, alkanesulfonate, and haloalkanesulfonate;
• and
• n=2 to 6;
• and
• ii) from about 10 to about 75 wt % of a hydrophobic monomer comprising an aliphatic alkyl (meth)acrylate monomer having a hydrocarbon group of from 1 to 12 carbon atoms;
• and
• iii) from about 2 to about 25 wt % of a crosslinkable monomer having the formula:
• CH2═CR3Y
• wherein
• R3 is H or CH3;
• and
• Y is selected from the group consisting of CO2M, L-CO2M, L-OH, and CONH2, wherein M is H or a counterion, and L is a divalent linking group comprising alkylene, arylene, heteroalkylene, ether, carbonyl, ester, amido, or sulfonamido functionality, or a combination thereof;
• b) a non-cationic (meth)acrylic polymer which comprises no monomer with —OH or —CO2H functional groups;
• and
• c) a crosslinking agent selected from the group consisting of melamine-formaldehyde, urea-formaldehyde, glycoluril-formaldehyde, aziridine, carbodiimide, isocyanate, and epoxy crosslinkers.
