The present invention provides an adhesive sheet (surface protective film) which is excellent in adhesiveness, removability, pick-up property, workability, and can prevent an increase in adhesion over time and has a surface coating excellent in whitening resistance. An adhesive sheet having an adhesive layer formed of an adhesive composition on one side of a support film, and the support film having a top coat on a side opposite to a surface having the above adhesive layer, The surface coating layer comprises a wax as a lubricant and a polyester resin as a binder, and the back surface adhesion force at a peeling speed of 0.3 m/min after being attached to the surface of the top coat layer at 23 ° C for 30 minutes (A) The adhesive force ratio (A/B) of the adhesive force (B) at a peeling speed of 30 m/min after the adhesive surface of the pressure-sensitive adhesive layer was attached to the TAC surface at 50 ° C for one week was 3 or more. |
