Abstract
To provide a low-viscosity pressure-sensitive adhesive which can contribute to the saving of petroleum resources by increasing the ratio of an environmentally friendly material, has heat resistance, wet heat resistance, and yellowing resistance, and can achieve a high solid content, and to provide a pressure-sensitive adhesive sheet using the same, a laminate, and a device with a pressure-sensitive adhesive layer.SOLUTION: A pressure-sensitive adhesive containing an acrylic copolymer (A) that is a copolymer of a monomer mixture containing specific amounts of 2-octyl (meth) acrylate, an alkyl (meth) acrylate having an alkyl group having 1 to 4 carbon atoms, and a monomer having a carboxy group, or a pressure-sensitive adhesive composition containing the acrylic copolymer (A).SELECTED DRAWING: Figure 1
