Title (EN) REPOSITIONABLE SHEETS
(FR) FEUILLES REPOSITIONNABLES
Abstract:
(EN) A repositionable sheet comprising a backing having front and back major surfaces and an adhesive on at least a portion of the back major surface, wherein the adhesive is an acrylic pressure sensitive adhesive derived from the reaction product of: (a) an acrylic acid ester of monohydric alcohol having an alkyl group of 5 to 10 carbon atoms; and (b) a nonpolar acrylic monomer having a solubility of less than about 9.2 as measured by the Fedors method using a homopolymer of the nonpolar acrylic monomer, wherein the reaction product has side chain crystallinity.
(FR) La présente invention concerne une feuille repositionnable comprenant un support ayant des surfaces principales avant et arrière et un adhésif sur au moins une partie de la surface principale arrière. L'adhésif est un adhésif acrylique sensible à la pression dérivé du produit de réaction de : (a) un ester d'acide acrylique d'alcool monohydrique contenant un groupe alkyle de 5 à 10 atomes de carbone ; et (b) un monomère acrylique non polaire ayant une solubilité inférieure à environ 9,2 telle que mesurée par le procédé de Fedors au moyen d'un homopolymère du monomère acrylique non polaire. Le produit de réaction présente une cristallinité de chaîne latérale.
