Abstract
An adhesive composition which is reduced in gas generation upon heating (has low hygroscopicity), has high alkali resistance, has heat resistance of 200° C. or higher, and can be easily removed with a stripping liquid; and an adhesive film made with the adhesive composition. The adhesive composition is prepared using, at least as a major ingredient, an acrylic polymer produced from (a) styrene, (b) a (meth)acrylic ester monomer containing a cyclic skeleton, and (c) an alkyl (meth)acrylate monomer. The adhesive film has an adhesive composition layer formed from this adhesive composition.
