(57) [Abstract] [Purpose] An object of the present invention is to show that the adhesive strength does not increase with time after being adhered to the surface of an adherend such as a synthetic resin plate or a metal plate. Moreover, it is to provide a method for producing a pressure-sensitive adhesive tape for surface protection, in which the pressure-sensitive adhesive does not transfer to the surface of the adherend. According to the present invention, one surface of a substrate film is coated with a pressure-sensitive adhesive containing a cross-linking agent, dried to form a pressure-sensitive adhesive layer, and then heat treated at 50 to 80 ° C. for surface protection. Manufacturing method for adhesive tape. |
