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.)
(FR)
Cette invention concerne une composition d'agent antiadhésif comprenant une résine polyester (A) et un polymère acrylique (B), dans laquelle : le polymère acrylique (B) comprend la formule structurale (1) à titre de motif structural ; et le rapport (A):(B) entre la quantité de mélange de ladite résine polyester (A) et la quantité de mélange dudit polymère acrylique (B) est compris dans la plage de 50:50 à 95:5 en rapport en poids. L'invention concerne une feuille antiadhésive, une feuille adhésive simple face, et une feuille adhésive double face formées à partir de ladite composition d'agent antiadhésif. Il est également possible d'empêcher le transfert de la composition d'agent antiadhésif sur la surface d'un matériau de base de la feuille antiadhésive quand la feuille antiadhésive formée à partir de la composition d'agent antiadhésif est enroulée pour obtenir un rouleau, et de conférer une faculté d'antiadhésivité accrue à la feuille antiadhésive. (Dans la formule, R1 est H ou CH3, et R2est un groupe alkyle en C10-30 ayant une structure ramifiée).
