| titleOfInvention | Adhesive composition and adhesive sheet |
| abstract | 【Task】 It has sufficient adhesive strength and high tackiness, exhibits good removability even on highly polar adherends such as SUS and steel plates that tend to leave adhesive when peeled, and exhibits good removability even under high temperature or moist heat conditions when attached. A pressure-sensitive adhesive composition and a pressure-sensitive adhesive sheet that have sufficient removability even when stored for a long period of time under the same conditions, and the pressure-sensitive adhesive does not protrude from the sheet even under high temperature and high load conditions when attached, To provide a pressure-sensitive adhesive composition and a pressure-sensitive adhesive sheet capable of stacking and storing heavy adherends such as steel plates even at high temperatures. [Solution] Acrylic is a copolymer of a monomer mixture consisting of a (meth)acrylic acid alkyl ester monomer (A) having an alkyl group with 1 to 12 carbon atoms, a monomer (B) having an acidic group, and a monomer (C) having a hydroxyl group. The content of the monomer (B) containing an acid ester copolymer and an isocyanate curing agent and having an acidic group is 0.01% by mass or more and 6% by mass or less in 100% by mass of the monomer mixture. The content of the monomer (C) is 0.05% by mass or more and 10% by mass or less in 100% by mass of the monomer mixture, and the adhesive composition has a gel fraction of 55% or more. [Selection figure] None |
