Document Type and Number:
Japanese Patent JP7406908
Kind Code:
B2
Abstract:
An objective of the present invention is to provide a glass scattering prevention sheet with an increased scattering prevention performance. To achieve this, according to the present invention, the glass scattering prevention sheet (1) adheres to a cover glass of a capacitive touch panel disposed on a visual side surface of a mobile device to prevent scattering of glass fragments when the cover glass is broken. The sheet is made of an adhesive sheet having an adhesive layer (11) formed of an adhesive composition formed on one side of a film substrate (12). The sheet can be peeled off without a stick-slip phenomenon when an adhesive layer surface of the adhesive sheet is bonded to a glass having a thickness of 3 mm with a roller having a load of 2 kgf at a temperature of 23°C and a relative humidity of 50% and the adhesive sheet was quickly peeled off from the glass at a speed of 30,000 mm/min in a 180 degree direction after 30 minutes.
