Patent ID: 8460574

Claim:
An antistatic adhesive composition, comprising: 100 parts by weight of a (meth)acrylic adhesive resin, the (meth)acrylic adhesive resin having functional groups capable of bonding with a cross-linking agent; about 0.01 to about 15 parts by weight of a cross-linking agent; and about 0.1 to about 10 parts by weight of an ammonium salt, the ammonium salt being obtained by reacting an amine having three terminal hydroxyalkyl groups with one of an organic or inorganic acid, wherein: the amine is a tertiary amine oligomer, and the tertiary amine oligomer has a weight average molecular weight of about 1,000 to about 2,000, and the ammonium salt is represented by Formula 1: wherein: R 1 and R 3 are each independently a C 2 -C 12 linear alkyl, a C 2 -C 12 branched alkyl, an alkoxyalkyl, or a carboxyalkyl, R 2 and R 4 are each independently hydrogen, a C 1 -C 12 linear alkyl, a C 1 -C 12 branched alkyl, an alkoxyalkyl, or a carboxyalkyl, provided that exactly one of R 2 and R 4 is hydrogen, m and n are each independently 0 or 1, with the proviso that: when R 2 is hydrogen, m=0 and n=1, and when R 4 is hydrogen, m=1 and n=0, and X is a counter anion derived from the organic or inorganic acid.
