Adhesives having a microreplicated topography are prepared from contacting a microembossed pattern to a layer of adhesive. When an adhesion interface is established between the layer of adhesive and a supporting substrate, the topography of the adhesive surface controls the performance of the adhesion interface. Articles having microreplicated adhesive surfaces are also disclosed that have an advantage of providing microchannels for fluid egress for an effective period of time. Multiple microeombossed patterns produce microreplicated adhesive surfaces having both microchannels for fluid egress and pegs for improved adhesive properties.

An adhesively mountable image using a non-tacky reusable adhesive surface is provided. The image carrier is removable from the adhesive carrier, and a subsequent image carrier may be releasably bound to the same adhesive carrier. Kits for this system are also provided.

Films having a microreplicated topography are prepared from contacting a microembossed pattern to a layer of film. When an adhesion interface is established between the layer of film and a supporting substrate, the topography of the film surface controls the performance of the adhesion interface. Articles having microreplicated film surfaces are also disclosed that have an advantage of providing microchannels for fluid egress for an effective period of time. Multiple microembossed patterns produce microreplicated film surfaces having both microchannels for fluid egress and pegs for improved film properties.

A web of material has a plurality of stems extending from at least one side of the web. The web includes a first layer of material having a first side and a second side and a second layer of material. The second layer of material has a first side which faces the first side of the first layer and a second side from which the plurality of stems extend. The first and second layers of material are joined together while they are both molten, before either layer has cooled. The first and second layers of material can be formed of thermoplastic material or melt processable polymeric material. A method of making a web of material includes selecting a first material for a first layer of material and selecting a second material for a second layer of material. The first and second layers of material are melt formed. Then, the first and second layers of material are joined while the layers are in the molten state to form a multiple layer sheet. Next, a plurality of stems are formed on at least the second layer of material. Melt forming can include simultaneously melt forming the first and second layers of material such as by coextrusion.
