The present invention provides a pressure-sensitive adhesive composition and a pressure-sensitive adhesive film having excellent anti-clouding performance, even when the pressure-sensitive adhesive layer is thickly applied, which does not become cloudy even when left in a high temperature and high humidity atmosphere for a long time. (A) 0.1-10 weight part of at least 1 sort (s) or more of the copolymerizable monomer containing a hydroxyl group (B) with respect to 100 weight part of at least 1 sort (s) or more of the (meth) acrylic acid ester monomers of C1-C18 alkyl group. The acrylic polymer composed of a copolymer having a weight average molecular weight copolymerized at a ratio of 200,000 to 2 million and having an acid value of 5.0 or less, and R 1 COO- (R 3 -O) n -CO-R 2 (wherein R 1 and R 2 are An alkyl group having 4 to 17 carbon atoms, R 3 is an alkylene group having 2 to 5 carbon atoms, n represents an integer of 3 to 25), at least one or more of the (C) diester compounds, (D) an isocyanate compound, (E) It contains antioxidant. |
