Abstract
(EN)
This release agent composition comprises a polyester resin (A) and an acrylic polymer (B), wherein: the acrylic polymer (B) includes structural formula (1) as a structural unit; and the ratio (A):(B) between the blending amount of said polyester resin (A) and the blending amount of said acrylic polymer (B) ranges from 50:50 to 95:5 in mass ratio. The present invention can provide a release sheet, a single-faced adhesive sheet, and a double-faced adhesive sheet formed from said release agent composition. Also, it is possible to keep the release agent composition from transferring onto the surface of a base material of the release sheet when the release sheet formed from the release agent composition is wound up into a roll, and to provide the release sheet with easy releasability. (In the formula, R is H or CH1 is H or CH, and R3, and R is a C2 is a C alkyl group having a branched structure.)10-30 alkyl group having a branched structure.)
