| abstract |
The stripping agent composition comprises a polyester resin (A) and an acrylic polymer (B), wherein the acrylic polymer (B) takes the following structural formula (1) as a constitutional unit, and the mass ratio of the mixing amount ratio of the polyester resin (A) and the acrylic polymer (B) is (A): (B) 50: 50-95: 5. The invention also provides a release sheet, a single-sided adhesive sheet and a double-sided adhesive sheet which are composed of the release agent composition. Further, when the release sheet composed of the release agent composition is rolled in a roll shape, the release agent composition is prevented from transferring to the surface of the release sheet base material, and light releasability can be imparted to the release sheet. ... (1) (in the formula, R 1 Is H or CH3, R 2 An alkyl group having a branched structure and having a carbon number of 10 to 30). |
