Acrylic pressure sensitive adhesive composition

An acrylic adhesive composition comprising:

• a) 100 parts by weight of an acrylic copolymer;
• b) 0.001-25 parts by weight of a room temperature eutectic salt prepared by mixing a metal salt represented by the formula (1) below, composed of an anion having a perfluoroalkane group, which is a conjugate base of a super acid, and an alkali metal cation with a compound having an amide group represented by the formula (2) below;
• and
• c) 0.01-10 parts by weight of a polyfunctional crosslinking agent:
• M+X−(YOmRf)n (1)
• where M is an alkali metal cation and Rf is a perfluoroalkane group having 1-4 carbon atoms (If Y is carbon, m=1. If Y is sulfur, m=2. If X is oxygen, n=1. If X is nitrogen, n=2. If X is carbon, n=3.);
• where R1 is hydrogen, an alkyl group having 1-10 carbon atoms, an alkenyl group having 2-10 carbon atoms or an aryl or alaryl group having 6-10 carbon atoms;
• R2 is hydrogen, halogen, an alkyl group having 1-10 carbon atoms, an alkenyl group having 2-10 carbon atoms or an aryl or alaryl group having 6-10 carbon atoms;
• X is carbon or nitrogen;
• and n is 0-6.
