Abstract: 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 microembossed patterns produce microreplicated adhesive surfaces having both microchannels for fluid egress and pegs for improved adhesive properties.

Abstract: A sign having raised or recessed, three-dimensional graphics and a method of making the sign are disclosed. The sign is fabricated from a laminated, multi-layered blank having a substantially continuous face layer formed of a conformable, thermoplastic material; a substantially continuous middle layer formed of a colored film; and a substantially continuous profile layer formed of a profile film. In use, dimensional characters are cut into the blank through the profile and middle layers only. Unwanted material is weeded out from around the cut, dimensional characters, and the resulting blank is vacuum-thermoformed to cause the uncut face layer to conform to the dimensional characters. A background sheet of a color contrasting to the middle sheet is then laminated to the back of the blank to form the completed sign.

Abstract: A 3-D graphic sign construction is provided comprising: (a) a conformed laminate comprising a sign face layer, one or more visual characters, a background color layer, and (b) one or more 3-D characters positioned in register with the visual characters and a method of make the same.

Abstract: A hydroxyorganosilane composition which upon curing provides a polymer that is an electrical conductor is disclosed. The composition comprises 1 to 95 weight percent of a hydrolyzate of a hydroxyorganosilane and optionally up to 50 weight percent of a silanol-sulfonate compound. When the cured polymer, which has a siloxane backbone, is a film in a composite structure, the resultant article has antistatic properties.
