<p>The present invention relates to a protective film having an adhesion layer, is formed by an adhesive composition including (matte) acrylic ester copolymers (A), which are obtained by the living radical polymerization of the adhesion layer and have weight-average molecular weight (Mw) of 400000-2000000 and molecular weight distribution (Mw/Mn) value of less than 2.5, and isocyanate group crosslinking agents (B) and organic tin compounds (C). The (matte) acrylic ester copolymers (A) includes tellurium metal. The weight ratio of the organic tin compound (C) and the tellurium metal is 2:1-20:1. The present invention is able to provide the protective film which is attached to a substrate with sufficient adhesion and minimizes the attachment of residues on the substrate in exfoliation.</p> |
