Title
(EN) Release agent composition, release sheet, single-faced adhesive sheet, and double-faced adhesive sheet
(ZH) 剥离剂组成物、剥离薄板、单面粘合薄板和双面粘合薄板
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, R1 is H or CH3, and R2 is a C10-30 alkyl group having a branched structure.).
