1. A protection film, comprising:
a base; and an adhesive layer that comprises an acrylic pressure sensitive adhesive composition and is formed on one or both surfaces of the base, wherein the composition comprises:
(i) an acrylic copolymer prepared by copolymerization of monomers comprising: 90 to 99.9 parts by weight of (meth)acrylic ester monomer having C1-C12 alkyl, 0.1 to 10 parts by weight of a monomer represented by Formula 3, and 0.1 to 10 parts by weight of a monomer having a crosslinking functional group, relative to 100 parts by weight of the total monomers;(ii) a crosslinking agent;(iii) a chelating agent capable of forming a bond with a metal ion, wherein the chelating agent is present in an amount of 0.01 or more and less than 2 parts by weight, relative to 100 parts by weight of the acrylic copolymer; and(iv) a metal salt, wherein the metal salt is present in an amount of 0.001 or more and less than 0.3 parts by weight, relative to 100 parts by weight of the acrylic copolymer, wherein the base comprises one or more films selected from the group consisting of a cellulose film, a polyester film, a polyether film and a polyolefin film, and wherein the adhesive layer has a low-rate peel strength of 3.5-9.1 gf/in for a triacetyl cellulose film and 5.3-10.8 gf/in for an anti-glare triacetyl cellulose film with an angle of 180° at a peeling rate of 0.3 m/min, and a high-rate peel strength of 100-130 gf/in for a triacetyl cellulose film and 95-135 gf/in for an anti-glare triacetyl cellulose film with an angle of 180° at a peeling rate of 30 m/min: wherein, R1 is hydrogen or C1-C10 alkyl; R2 and R3 are independently C1-C10 alkylene; R4 is phenyl, benzyl, C1-C10 alkyl or C1-C10 alkoxyalkyl; m is 0 or an integer from 1 to 6; and n is an integer from 1 to 100, with proviso that m is 0, n is an integer from 2 to 100. |
