Abstract: Provided is a Low-E glass plate protection method capable of preventing or inhibiting Low-E layer alteration. The protection method includes a step of applying a protective sheet to a surface of a Low-E glass plate having a Low-E layer comprising a zinc component. Here, the protective sheet has a PSA layer. The Low-E layer comprises a zinc component. The PSA layer includes ammonia and an acid or acid salt capable of forming a counterion to an ammonium ion.

Abstract: To provide a method for protecting a Low-E glass plate, the method being capable of preventing or inhibiting alteration of Low-E layers. Provided is a Low-E glass plate protection method. The protection method includes a step of applying a protective sheet to a surface of a Low-E glass plate having a Low-E layer comprising a zinc component. Here, the protective sheet has a PSA layer. The Low-E layer comprises a zinc component. The PSA layer includes an adsorbent capable of adsorbing ammonia.

Abstract: A pressure-sensitive adhesive sheet includes a resin film as a substrate and a pressure-sensitive adhesive layer provided on a first face of the substrate. In the pressure-sensitive adhesive sheet, a second face of the substrate is a release face, and the second face has a slip resistance value of 3.5 N or more. The pressure-sensitive adhesive sheet has a high-speed peel strength of 4.5 N/20 mm or higher, which is measured under conditions of a tensile speed of 30 m/min after 30 minutes of application to a stainless steel plate, and it has a difference between the maximum and minimum values of a self-backside adhesive strength of 1.5 N/20 mm or lower, which is measured under a condition of a tensile speed of 30 m/min.

Abstract: Provided is a Low-E glass plate protection method capable of preventing or inhibiting Low-E layer alteration. In the protection method, a protective sheet having a substrate and a PSA layer provided to at least one face of the substrate is applied for protection via the PSA layer to a Low-E glass plate having a Low-E layer that comprises a zinc component. The method is characterized by using the protective sheet wherein the PSA layer is formed from a water-dispersed PSA composition and includes less than 850 ?g ammonia per gram of PSA layer weight.
