Embodiment

[0196] The present invention is further illustrated by the following examples. However, this invention is not limited and interpreted to the Example shown below.

[0197] In Examples 1 to 5 and Comparative Examples 1 to 2, the adhesive layer-forming composition compounded in the mass ratio shown in Table 1 was produced, and the release film (Mitsubishi Chemical Corporation, Ltd. Co., Ltd. PET film) was developed so that the thickness of the adhesive layer became 100 μm.

[0198] Next, for Examples 1 to 5 and Comparative Example 2, a release film with a thickness of 75 μm (PET film manufactured by Mitsubishi Chemical Corporation) subjected to silicone release treatment was further laminated on the adhesive layer to form a laminate, and a metal halide Lamp irradiation device (Ushio Inc., UVC-0516S1, lamp UVL-8001M3-N), the irradiation amount at a wavelength of 365nm is 2000mJ / cm 2 The aforementioned laminate was irradiated with light to obtain a laminate of an adhesive sheet i...

Abstract

Provided is a novel adhesive sheet which is capable of exhibiting an effect of sufficient corrosion prevention for silver and copper, and of which the relative permittivity and the temperature dependence thereof can be reduced. Proposed is a single-layer adhesive sheet including an adhesive layer containing a polyolefin, an acrylic polymer, and a nitrogen heterocyclic compound; or a multilayer adhesive sheet provided with the adhesive layer as a surface layer.

Description

technical field [0001] The present invention relates to a PSA sheet containing a rust preventive agent, a conductive member laminate using the same, and an image display device. Background technique [0002] In recent years, display devices such as liquid crystal displays (LCDs) and organic EL displays (OLEDs), and input devices such as touch panels have been widely used in various fields. In the manufacture of these display devices, input devices, etc., a transparent adhesive (OCA) sheet is used for bonding optical members. For example, acrylic transparent pressure-sensitive adhesive sheets are generally used for bonding optical members in various display devices such as touch panels. [0003] These display devices and input devices have a problem that metal wiring and transparent electrodes are corroded by corrosive components contained in transparent adhesive sheets and corrosive components that penetrate into the interior from the external environment. Furthermore, wit...
