PROBLEM TO BE SOLVED: To provide an adhesive sheet for protecting surface which has excellent staining and wettability to adherend, in which jamming of air bubble hardly occurs, which may be adhered with hands, and which has excellent adhesion and light detachability.SOLUTION: In an adhesive sheet for protecting surface of the present invention, in a case where the adhesive sheet for protecting surface comprising an adhesive agent layer obtained by crosslinking of adhesive agent composition containing polymer, minimum load of load curve of the adhesive agent layer surface by nanoindentation measurement is -0.3 μN or less and hardness of the adhesive agent layer surface is 0.1 MPa or more, after that standard adhesive tape is adhered on adhesive surface of adherend, adhesion upon detachment of the adhesive tape from the adhesive surface is defined as adhesion A, after that the adhesive agent layer surface of the adhesive sheet for protection is adhered on the adhesive surface of adherend, the adhesive sheet for protection is detached from the adhesive surface, in addition, standard adhesive tape is adhered on the adhesive surface from which the adhesive sheet for protection is detached, adhesion upon detachment of the adhesive tape from the adhesive surface is defined as adhesion B, remaining adhesion calculated with the following formula is 50% or more. Remaining adhesion (%)=100×[(adhesion B)/(adhesion A)].SELECTED DRAWING: None |
