PRESSURE-SENSITIVE ADHESIVE SHEET FOR SURFACE PROTECTION

摘要

The present invention provides a pressure-sensitive adhesive sheet for surface protection which has been laminated the following three layers of: (A) a layer which contains 60 - 100% by weight of an elastomer, containing 100 - 50% by weight of a hydrogenated random copolymer consisting of 1 - 50% by weight of styrene and 99 - 50% by weight of a diene hydrocarbon and 0 - 50% by weight of a low-molecular-weight elastomer, and 40 - 0% by weight of a polyolefin; (B) a layer which contains 3 - 95% by weight of a hydrogenated random copolymer consisting of 1 - 50% by weight of styrene and 99 - 50% by weight of a diene hydrocarbon and 97 - 5% by weight of a polyolefin; and (C) a layer which has at least one layer of a polyolefin, which has good adhesion to an object to be adhered, which can be easily removed (peeled off) from an object to be adhered after exposure to carbon arc, which has also good adhesion between the respective layers and which neither stains the surface to which the adhesive sheet is adhered nor leaves any adhesion mark thereon.
