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 μg ammonia per gram of PSA layer weight.
