Adhesive composition, adhesive film, and method for utilizing same

Abstract

The invention provides an adhesive composition comprising a copolymer of monomer components containing a first monomer, second monomer, third monomer and fourth monomer, wherein the first monomer is 2-ethylhexyl acrylate (2-EHA), second monomer is butyl methacrylate (BMA), ethyl methacrylate (EMA) or 2-ethylhexyl methacrylate (2-EHMA), or comprises all of the foregoing, third monomer is acrylic acid (AA), and fourth monomer is n-vinyl-2-pyrrolidone (NVP) monomer or acrylamide, or comprises both.

Description

technical field [0001] The present invention relates to an adhesive composition and an adhesive film. Background technique [0002] Recently, interest in the design of automobiles or vehicles has increased, and at the same time, interest in a scheme that can maintain such a design for a long period of time has also increased. [0003] As an example of a method of changing the design of a car or vehicle, there is a method of repainting its surface or exterior surface, but this method is too expensive, so as an alternative, wrap the car or vehicle with a predetermined film The surface or external surface method, that is, the packaging (wrapping) method is on the rise. [0004] As mentioned above, the adhesive film is used as a predetermined film for wrapping the surface or exterior surface of automobiles or vehicles. In the process of construction, the adhesive film needs to be adhered and peeled off for positioning. As one of the properties, the repositionable properties (r...

Problems solved by technology

[0005] However, commonly used adhesive films are made of acrylic compositions, but there is a problem that the above two physical properties cannot be simultaneously achieved at an excellent level.
