    • Medical dressings are disclosed that include multiple exposed pressure sensitive adhesives. One of the pressure sensitive adhesives includes a bioactive agent and is substantially contact transparent. In some embodiments, all of the adhesives are substantially contact transparent. Also provided are methods of manufacturing the medical dressings. By providing multiple exposed pressure sensitive adhesives, the pressure sensitive adhesive formulations can be varied to provide desired properties in different areas of the dressing. A pressure sensitive adhesive that exhibits relatively high tack to skin may be provided around the periphery of the dressing while a pressure sensitive adhesive incorporating a bioactive agent is provided in the center of the dressing. Alternatively, a higher tack pressure sensitive adhesive may be provided at two opposing sides of the dressing with a bioactive adhesive located in between the opposing portions of higher tack adhesive. The present invention also provides methods of transferring adhesives using a mask such that the adhesive is transferred to selected areas of a receiving surface. The mask may be provided in the form of a liner including a plurality of voids formed therein.
    • 公开了包括多个暴露的压敏粘合剂的医用敷料。 压敏粘合剂之一包括生物活性剂并且基本上是接触透明的。 在一些实施方案中,所有粘合剂基本上是接触透明的。 还提供了制造医用敷料的方法。 通过提供多个暴露的压敏粘合剂,可以改变压敏粘合剂制剂以在敷料的不同区域中提供所需的性质。 可以在敷料的周围设置在皮肤周围具有相对较高粘性的压敏粘合剂,同时在敷料的中心设置包含生物活性剂的压敏粘合剂。 或者,可以在敷料的两个相对侧设置较高的粘性压敏粘合剂,其中具有位于较高粘性粘合剂的相对部分之间的生物活性粘合剂。 本发明还提供了使用掩模转移粘合剂使得粘合剂被转移到接收表面的选定区域的方法。 掩模可以以包括形成在其中的多个空隙的衬垫的形式提供。

    • The present invention relates to graphic or informational articles that may be applied to a surface of a translucent or substantially clear substrate so that the image may be viewed through the substrate. The present invention is an indoor advertising system or kit that includes two components. The first component is a substantially clear, perforated imageable film layer with a perforated adhesive layer on a surface thereof. The second component is a non-perforated colorant transfer component that includes a removable carrier film with at least one color layer on a surface thereof. The present invention further includes a process for making the graphic articles. In the process of the present invention, an image layer is formed on a first major surface of a substantially clear, perforated imageable film layer. A colorant transfer component with at least one colored layer comprising a pigment is laminated to the imageable film layer such that the at least one colored layer is adhered to the unperforated areas of the image layer. The colorant adheres to the unperforated land areas of the image layer without significant bridging across the apertures of the image layer.
    • 本发明涉及可应用于半透明或基本上透明的基底的表面的图形或信息制品,以便可以通过基底观察图像。 本发明是一种包括两个部件的室内广告系统或套件。 第一组分是在其表面上具有穿孔粘合剂层的基本透明的可穿孔成像膜层。 第二组分是非穿孔着色剂转移组分,其包括其表面上具有至少一个着色层的可除去的载体膜。 本发明还包括制作图形制品的方法。 在本发明的方法中,在基本透明的可穿孔成像膜层的第一主表面上形成图像层。 将具有至少一种包含颜料的着色层的着色剂转印组分层压到可成像膜层上,使得至少一个着色层粘附到图像层的未穿孔区域。 着色剂粘附到图像层的未穿孔的陆地区域,而不会跨越图像层的孔径而显着桥接。
