Japanese Patent JP7244369

Kind Code:

B2

Abstract:

Provided is an antistatic surface protective film having adhesive force balanced at a low-speed exfoliation speed and a high-speed exfoliation speed, and capable of ensuring compatibility of antistatic performance and anti-fouling performance. For the antistatic surface protective film of the present invention, an adhesive composition includes: (A) an acryl-based polymer containing 50 or more parts by weight of 2-ethyl hexyl acrylate and 5 to 40 parts by weight of one or more of monofunctional methacrylate monomers having Tg of 0 ℃ or higher which a homopolymer has, based on 100 parts by weight of two or more of alkyl (meth)acrylates having C1-C10 carbon atoms of an alkyl group; (C) an isocyanate compound having three functionalities or more; (D) a cross-linking delaying agent; and (E) a cross-linking promoting agent other than a tin compound. The adhesive composition is applied to the surface of a cross-linked adhesive layer (2) and an exfoliating agent layer (4) is applied to an exfoliation film (5) having exfoliating agent layers (4) containing an antistatic agent, which are stacked and bonded thereto. The antistatic agent in the exfoliating agent layer (4) is transferred to the surface of the adhesive layer (2).
