  • Publication number: 20140313579
    Abstract: The present disclosure describes a front projection system. The front projection system includes a light absorbing layer having an absorbance in a visible range of the electromagnetic spectrum of at least 80% and a light diffusing layer disposed on the light absorbing layer between the light absorbing layer and the projector. The light diffusing layer includes a plurality of metal flakes uniformly distributed in a host material, an average size of the plurality of metal flakes being in a range from about 0.5 microns to about 20 microns, at concentration of in a range from about 3% to about 30% by weight. A plurality of light absorbing particles uniformly distributed in the host material at a concentration of less than about 7% by weight, and a major front surface facing the projector having an average surface roughness in a range from about 0.5 microns to about 10 microns.

  • Patent number: 6911243
    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 microeombossed patterns produce microreplicated adhesive surfaces having both microchannels for fluid egress and pegs for improved adhesive properties.

  • Patent number: 6531021
    Abstract: 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.

  • Patent number: 6436218
    Abstract: 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.

  • Patent number: 6106922
    Abstract: 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.
