    • There is provided a removable water-dispersible pressure-sensitive adhesive composition to form a pressure-sensitive adhesive layer of a pressure-sensitive adhesive sheet capable of exhibiting good curl regulatability. There are also provided a pressure-sensitive adhesive sheet capable of exhibiting good curl regulatability, and an optical component having the pressure-sensitive adhesive sheet laminated thereon. The removable water-dispersible pressure-sensitive adhesive composition according to the present invention forms a pressure-sensitive adhesive layer of a pressure-sensitive adhesive sheet having an initial curl height of not less than 20 mm as determined by a curl test, and a difference in curl height of not more than 10 mm as determined by the curl test. The pressure-sensitive adhesive sheet according to the present invention has a pressure-sensitive adhesive layer formed of the removable water-dispersible pressure-sensitive adhesive composition. The optical component according to the present invention has the pressure-sensitive adhesive sheet laminated thereon.
    • 提供一种可移除的水分散性压敏粘合剂组合物,以形成能够表现出良好卷曲调节性的压敏粘合片的压敏粘合剂层。 还提供了能够表现出良好的卷曲调节性的压敏粘合片,以及其上层叠有压敏粘合片的光学部件。 根据本发明的可去除的水分散性粘合剂组合物形成通过卷曲试验确定的初始卷曲高度不小于20mm的压敏粘合片的压敏粘合剂层, 卷曲高度不超过10毫米,由卷曲测试确定。 根据本发明的压敏粘合片具有由可去除的水分散性压敏粘合剂组合物形成的压敏粘合剂层。 根据本发明的光学部件具有层压在其上的压敏粘合片。

    • This invention relates to the modification of polyolefin structures, parts or components, used in assemblies to enhance the bonding of polar adhesives to surface of the polyolefin structures. Disclosed herein are novel articles comprising polyolefin structures having one or more surfaces modified according to the invention. The polyolefin structures have one or more surfaces with an epoxy resin layer disposed directly on the surface and then disposed on the epoxy resin layer is a layer of one or more compounds, oligomers or prepolymers having reactive isocyanate groups. The invention is also a method for modifying one or more surfaces of a polyolefin structure by successively depositing on the surfaces an epoxy resin layer disposed and a layer of one or more compounds, oligomers or prepolymers having reactive isocyanate groups. Also disclosed are kits of the modified polyolefin structures and one or more of adhesives or coatings having polar reactive groups. Further disclosed are methods of bonding the modified polyolefin structures to other substrates by contacting adhesives having polar reactive groups with the modified surfaces and the other substrates with the adhesive disposed therebetween. Also disclosed are coating methods which comprise contacting one or more coatings comprising polar reactive groups with the modified surfaces of the polyolefin structure.
    • 本发明涉及用于组件中用于增强极性粘合剂与聚烯烃结构表面的粘合的聚烯烃结构,部件或部件的改进。 本文公开了包含具有根据本发明修饰的一个或多个表面的聚烯烃结构的新型制品。 聚烯烃结构具有一个或多个表面,其中环氧树脂层直接设置在表面上,然后设置在环氧树脂层上,是一层或多层具有活性异氰酸酯基团的化合物,低聚物或预聚物。 本发明还是通过在表面上依次沉积设置的环氧树脂层和一种或多种具有反应性异氰酸酯基团的化合物,低聚物或预聚物的层来修饰聚烯烃结构的一个或多个表面的方法。 还公开了改性聚烯烃结构的试剂盒和一种或多种具有极性反应性基团的粘合剂或涂层。 进一步公开的是通过将具有极性反应性基团的粘合剂与改性表面和其它基材接触而将改性聚烯烃结构粘合到其它基材上的方法,其中粘合剂设置在其间。 还公开了包括使包含极性反应性基团的一种或多种涂层与聚烯烃结构的改性表面接触的涂覆方法。
