Abstract: A layered adhesive construction comprising a backing layer and a first and second layer of hydrocolloid adhesive, where the first and second layer of hydrocolloid adhesive have different composition, and the second layer of hydrocolloid adhesive is at least partly interposed between the first layer of hydrocolloid adhesive and the backing layer, the first and second adhesive layers consisting of a continuous phase and a discontinuous phase where the discontinuous phase of the first adhesive layer comprises a hydrocolloids providing a higher moisture absorption capacity and higher initial rate of absorption to the adhesive layer than the hydrocolloids in the discontinuous phase of the second adhesive layer, and the discontinuous phase of second layer of adhesive comprises hydrocolloids providing a higher cohesion following moisture absorption to the adhesive compared to the hydrocolloid in the discontinuous phase of the first adhesive layer.
