WIPO Patent Application WO/2020/137955
Kind Code:
A1
Abstract:
Provided is an adhesive sheet which has anti-metal corrosion properties and can therefore be used even on a metal adherend and which can also prevent or inhibit contamination of the surface of the adherend while maintaining good removability even when adhered to the adherend for a long period of time. An adhesive sheet which includes an adhesive layer is provided. The adhesive layer contains a base polymer at a proportion of at least 95% by weight. Moreover, the chloride ion content as measured by hot water extraction is less than 300μg per gram of the adhesive layer.
