Antistatic surface protection film
歐洲專利號(hào)Priority number:TW201542744
Abstract:The present invention provides an antistatic surface protection film that have little contamination of an adherend and that have superior peeling antistatic performance which does not deteriorate over time. The present invention is made by, in order: a step of forming, on one surface of a base film 1 including a transparent resin, an adhesive layer 2 including an adhesive composition, which includes an acrylic-based polymer of a copolymer, and which further contains (D) a bifunctional or higher isocyanate compound, (E) a cross-linking promoting agent of a metal chelate compound, (F) a keto-enol tautomer compound; a step of attaching a peeling film 5, which has a release agent layer 4 containing an antistatic agent laminated on one surface of a resin film 3, on a surface of the adhesive layer 2 via the release agent layer 4, wherein the release agent layer 4 is formed by a resin composition including: a release agent having dimethylpolysiloxane as the main component; a silicone-based compound that is a liquid at 20 DEG C; and an antistatic agent, wherein the peeling charge pressure of theadhesive layer 2 is +- 0.6 kV or less.
