According to the present invention, there are provided a removable pressure sensitive adhesive sheet applicable even to a coating film incompletely cured immediately after having been dried and a method of protecting an incompletely cured coating film. The removable pressure sensitive adhesive sheet of the present invention is a removable pressure sensitive adhesive sheet characterized in that the sheet is obtained by providing a substrate sheet with a pressure sensitive adhesive layer, and that the pressure sensitive adhesive layer has a storage elastic modulus at 23° C. of 1.0×105 Pa or more and a storage elastic modulus at 80° C. of 0.4×105 Pa or more. The sheet is applicable even to an incompletely cured coating film.
A removable pressure sensitive adhesive sheet to be stuck to a coating film wherein a pressure sensitive adhesive layer is formed on a substrate sheet, which comprises the pressure sensitive adhesive layer having a storage elastic modulus at 23° C. of 1.0×105 Pa or more and a storage elastic modulus at 80° C. of 0.4×105 Pa or more.
A method of protecting an incompletely cured coating film, the method comprising sticking, to the incompletely cured coating film, a removable pressure sensitive adhesive sheet obtained by providing a substrate sheet with a pressure sensitive adhesive layer having a storage elastic modulus at 23° C. of 1.0×105 Pa or more and a storage elastic modulus at 80° C. of 0.4×105 Pa or more.
