Abstract
[Problem] To provide a thermoplastic resin composition which is excellent in transparency and adhesion properties and hardly causes staining of an adherend after it is separated, a multilayer laminate using the composition, an article, and a method for protecting a surface of an article. [Means for solving problem] A thermoplastic resin composition (X) comprising the following components (A) to (C): (A) isotactic polypropylene containing not less than 90% by mol of propylene units, in an amount of 1 to 65% by weight, (B) a propylene copolymer which is a copolymer of propylene and at least one α-olefin of 2 to 20 carbon atoms (excluding propylene) and whose melting point, as measured by DSC, is lower than 65° C. or is not observed, in an amount of 30 to 94% by weight, and (C) a 1-butene-based polymer which is selected from the group consisting of a 1-butene homopolymer and a copolymer of 1-butene and an α-olefin of 2 to 20 carbon atoms (excluding 1-butene) (said copolymer containing not less than 16% by mol of 1-butene units) and whose melting point, as measured by DSC, is in the range of 65 to 135° C., in an amount of 5 to 60% by weight, the total amount of said components (A) to (C) being 100% by weight.
