1. A pressure-sensitive adhesive sheet having a supporting film, a pressure-sensitive adhesive layer formed from a pressure-sensitive adhesive composition on one surface of the supporting film, and a top coat layer on the other surface opposite to the surface having the pressure-sensitive adhesive layer of the supporting film, wherein
the top coat layer contains wax as a lubricant and a polyester resin as a binder; and an adhesive strength ratio (A/B) of the rear surface adhesive strength (A) at a peel rate of 0.3 m/min after the surface of the top coat layer is bonded at 23° C. for 30 minutes and the adhesive strength (B) at a peel rate of 30 m/min after the pressure-sensitive adhesive surface of the pressure-sensitive adhesive layer is bonded to a TAC surface at 50° C. for 1 week is 3 or higher. |
