  • Patent number: 6890400
    Abstract: Overlaminated faceless PSA label constructions of this invention comprise a low material cost, thin prelaminate PSA construction having a layer of pressure-sensitive material disposed on a release surface of a removable substrate, and a nonblocking continuous film disposed over a surface of the layer of pressure-sensitive adhesive to render the pressure-sensitive adhesive tack free. An optically transparent overlaminate film layer is disposed over the nonblocking continuous film, and a printed indicia is interposed between the overlaminate film layer and nonblocking continuous film. The prelaminate PSA construction does not include a conventional facestock formed from paper, cardboard or plastic, and is highly conformable.

  • Patent number: 6720025
    Abstract: A method of slot extrusion coating is provided that can be used to apply thin coatings using liquid compositions having high percent solids. A window of operability advantageously identifies the limits of a process to provide these thin high solids coatings. The window of operability is determined by obtaining a first graphical curve representing actual values of wet thickness as a function of percent solids level. The critical wet thickness is then identified on the first graphical curve. The window of operability is identified as an area defined by the boundaries: percent solids greater than the point at which critical wet thickness occurs, an actual wet thickness greater than all points above the first graphical curve and equal to or less than the critical thickness.

  • Patent number: 5415993
    Abstract: A photographic emulsion containing: a photosensitive silver halide; a light-insensitive, reducible silver source; a reducing agent for the light-insensitive, reducible silver source; and a binder consisting essentially of poly(vinyl butyral) having a poly(vinyl alcohol) content of about 17.5 to 21.0 wt. % and at least one solvent selected from the group consisting of: toluene, methyl ethyl ketone, acetone, tetrahydrofuran, and 1,4-dioxane. Additionally, a process for coating a substrate involving applying at least one layer of a molten thermoreversible organogel layer; causing it to gel; and removing residual solvent.

  • Patent number: 5378542
    Abstract: Process for the simultaneous application of at least two molten, thermoreversible organogel layers to a substrate. The organogel layers can optionally contain dispersed additive ingredients, such as pigments. The organogel layers are coated onto a suitable substrate and then rapidly cooled or chilled to form a gel. Residual solvent is then removed. Multilayer coated films are thus formed with minimal interlayer mixing or interlayer diffusion of the additive ingredients.

  • Patent number: 5368894
    Abstract: A method is provided for producing a multilayered element having a top coat. The method includes the application of an undercoating to the upper surface of a support and the application of a continuous top coat coating composition to the surface of the undercoating. The undercoating includes a binder while the top coat composition includes one or more dissolved or dispersed materials and one or more solvents. At least one of the solvents is compatible with the binder. The composition and coating weight of the top coat composition and of the undercoating are controlled such that the ratio T/B is less than or equal to 3, whereinT is the coating weight of the compatible solvent(s), andB is the coating weight of the binder.
