<p>PROBLEM TO BE SOLVED: To provide an adhesive layer capable of forming an adhesive sheet which, when being peeled off from an adherend and, subsequently, another layer is to be disposed on the adherend surface where the adhesive sheet was adhered, can leave the surface of the adherend in a state having excellent wettability for the another layer and excellent adhesion (adhesiveness) between the adherend surface and the another layer.SOLUTION: Provided is an adhesive layer containing a base polymer and having the following characteristics (1) and (2): (1) a water contact angle of a surface of an adherend X is 70° or less after an adhesive sheet A, adhered to the surface of the adherend X and allowed to stand at an air temperature of 23°C and humidity of 30% for 12 hours, is peeled off; and (2) adhesive strength of an acrylic tape to the surface of the adherend X, after the adhesive sheet A adhered to the surface of the adherend X and allowed to stand at an air temperature of 23°C and humidity of 30% for 12 hours is peeled off, is higher than adhesive strength of the acrylic tape to the surface of the adherend X.</p> |
