Abstract:
1. A multilayer laminate that is adherable to a substrate and selectively releasable therefrom upon application of an agent to an outer face or perimeter of the laminate and appropriate contacting between the agent and the adhesive, the laminate comprising: an interior layer defining a plurality of fluid passageway conduits or apertures extending through the interior layer, the interior layer exhibiting a controllable flow profile across the thickness of the interior layer, the interior layer defining a bottom surface and an oppositely directed top surface; an adhesive layer disposed along the bottom surface of the interior layer, wherein the adhesive layer includes channels incorporated in the adhesive layer of the multilayer laminate which allow for rapid ingress of an adhesive deactivating agent; a carrier layer is disposed on the top surface of the interior layer; wherein upon contacting the adhesive layer to the substrate, the laminate is adhesively adhered thereto; upon removal of the cover layer from the laminate, the interior layer and plurality of fluid passageway conduits are exposed; and upon application of an effective amount of the agent to the top surface of the interior layer, transport of the agent to the adhesive, and passage of sufficient contact time between the agent and the adhesive, the adhesively adhered laminate can be easily removed from the substrate.
