The present invention provides a surface-protective film for polarizing plate. The surface-protective film has excellent adhesion force balance under low peel speed and high peel speed, and has excellent attaching force to polarizing plate even in low adhesion force. Therefore, the surface-protective film has excellent durability, re-operability and antistatic ability.nA surface-protective film for polarizing plate composed by forming an adhesion agent layer in a surface of a resin film, wherein the adhesion agent layer is composed by crosslinking adhesion agent composition having an acrylic polymer, a crosslinking agent and an antistatic agent, characterized in that: the acrylic polymer is composed by a copolymer which is copolymerized by (A) a (meth)acrylate Monomer having an alkyl group with 4 to 18 carbon atoms, (B) a copolymerizable monomer having hydroxyl group and (C) a copolymerizable monomer having carboxyl group. In the shear holing power test for polarizing plate under loading 500g and leaving 24 hours at 23℃, the surface-protective film for polarizing plate attached in the polarizing plate does not have dislocation. |
