Adhesive compositions comprising one or more silicone/acrylate copolymers are described. Also described are various healthcare adhesive articles in sheet form which include a carrier sheet, a release coating applied to the carrier sheet, one or more regions of pressure sensitive adhesive adjacent the release coating, a flow control layer for promoting distribution of one or more adhesive debonding agents, and a substrate or facestock sheet removably disposed on the carrier sheet. The adhesive layer includes a pressure sensitive adhesive having a minority proportion of a silicone containing agent blended with one or more acrylic polymers. After application to a surface of interest, the adhesive strips can be easily removed by application of a debonding agent.
