Title:
貼り替え可能な微小球粒子接着剤塗布物品
Document Type and Number:
Japanese Patent JP5485864
Kind Code:
B2
Abstract:
An adhesive coated article comprises a layer of microsphere adhesive onto a portion of at least one major surface of a substrate. The microspheres in the adhesive are obtained as the reaction product of (a) at least one alkyl (meth)acrylate ester wherein the alkyl group contains four to about 14 carbon atoms, preferably four to about 10 carbon atoms and (b) a comonomer(s). The comonomer may be a nonpolar, ionic, polar comonomer or mixtures of such monomers. This microsphere adhesive either contains a (meth)acrylamide comonomer or a polyacrylamide material is post-added to the microsphere adhesive. The adhesive exhibits a lower than expected adhesion to coated papers without sacrificing the adhesion to standard uncoated (bond) papers and the 90 DEG peel adhesion, as measured on Kromkote TM paper (used as an industry standard) is in the range of 20 to 250 grams/inch.
