A release agent composition of the present invention comprises a polyester resin (A) and an acrylic polymer (B) having the following structural formula (1) as a constituent unit, the aforementioned polyester resin ( The ratio of the blending amount of A) to the blending amount of the aforementioned acrylic polymer (B) is calculated by mass ratio as (A): (B) = 50:50 to 95:5. Structural formula (1) is □, R1nFor H or CH3n, R2nIt is an alkyl group having a branched structure and having a number of carbon atoms of 10 or more and 30 or less. According to the present invention, a release sheet, a single-sided adhesive sheet and a double-sided adhesive surface formed of such a release agent composition can be provided. When the release sheet formed by the release of the release agent composition is formed into a roll shape, the release of the release agent composition to the surface of the substrate of the release sheet can be suppressed and the release sheet can be imparted with light release property. |
