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.
