Document Type and Number:
WIPO Patent Application WO/2014/034580
Kind Code:
A1
Abstract:
Provided is a surface protection sheet wherein it is possible to inhibit "floating" or "peeling" from occurring between inner sheets and it is possible to easily peel off only the outer sheet when peeling off the outer sheet for the purpose of exposing the inner sheet. This surface protection sheet, in which n (n represents an integer of 2 or greater) layers of adhesive sheets having a base layer and an adhesive agent layer are laminated in the order of one to n, is characterized in that the adhesive agent layers of the first to (n-1)th adhesive sheets respectively come into contact with the base layers of the second to nth adhesive sheets, and the adhesive force of the nth adhesive sheet (against a glass plate, at a tension rate of 300 mm/sec and at a peeling angle of 180°) is greater than the adhesive force of the (n-1)th adhesive sheet (against a PET film, at a tension rate of 300 mm/sec and at a peeling angle of 180°).
