Abstract
A release agent composition may include a polyester resin (A) and an acrylic polymer (B) in which the acrylic polymer (B) may include a structural unit represented by any structural formula disclosed herein, and a ratio of a blending amount of the polyester resin (A) to a blending amount of the acrylic polymer (B) may be in the range of (A):(B)=50:50 to 95:5 in a mass ratio. The release agent composition may be used to form a release sheet for a single-sided pressure-sensitive adhesive sheet or release sheets for a double-sided (faced) pressure-sensitive adhesive sheet. Further, when the release sheet is wound up in a rolled form, it is possible to suppress the release agent composition from transferring to a surface of the base material of the release sheet and to impart an easy peeling property to the release sheet.
