Adhesive Composition And Surface Protection Film

Abstract

The present invention provides an adhesive composition which possesses an anti-static performance, is excellent in binding force balance at low peel-away speed and high peel-away speed, is long in storage period, and is also excellent in durability and reprocessability. The adhesive composition of the present invention comprises (A) a (meth) acrylate monomer of which the carbon number of alkyl is C4-C18, (B) a copolymerizable monomer having hydroxide radical, (C) a copolymerizable monomer having carboxyl, (D) a poly alkylene glycol single (meth) acrylate monomer, (E) a vinyl monomer having nitrogen instead of hydroxy or alkyl(meth)acrylates having alkoxy, acrylic copolymer of copolymer of which the acid value is 0.01-8.0, (F) a bifunctional isocyanate compound, (G) a crosslinking catalyst of a metallo-chelate, (H) a ketone-enol tautomer compound, (I) an antistatic agent, (J) a polyether modified silicone compound, and (K) an antioxidant.

Description

technical field

[0001] The invention relates to an adhesive composition and a surface protection film. In more detail, the present invention relates to the provision of a polarizing plate having antistatic properties, excellent balance of adhesive force at low peeling speed and high peeling speed, long shelf life, durability, and reworkability. Adhesive composition for surface protection film and surface protection film. Background technique

[0002] For adhesives for optical applications, from the viewpoint of excellent transparency, it is preferable to use an alkyl (meth)acrylate copolymerized with an acrylic monomer having a hydroxyl group, a carboxyl group, etc. as a functional group. Acrylic adhesive composed of In addition, adhesives that appropriately adjust various physical properties such as adhesive force are required. In particular, in order to be suitable for the manufacturing process of factory production, adhesives for surface protection films, etc., require...
