Abstract
A protection sheet is provided for application to a vehicle window plate to protect the window plate. Protection sheet includes a substrate and a PSA layer provided on one surface of substrate. Protection sheet has a 30-minute peel strength (S1) of less than 0.10 N/20 mm and a 48-hour peel strength (S2) of 0.05 N/20 mm or greater when applied to a glass plate by a wet application method where water is provided to the surface of the glass plate and protection sheet is press-bonded to the glass plate while pushing the water present between the glass plate surface and PSA layer to the outside of the bonding area.
