PROBLEM TO BE SOLVED: To provide a heat shrinkable label which shrinks less of itself, is stiff and tough and is well finished. SOLUTION: This label is formed of an intermediate layer A consisting of a polystyrene or high-impact polystyrene resin of <=10wt.% butadiene content and outer layers B, C which consist of a styrene-butadiene block copolymer or styrene-butadiene-acrylic acid block copolymer and are formed on both surfaces of this intermediate layer A. The thickness of the intermediate layer A is 40 to 80% of the overall thickness. The label has a heat shrinkable film 1 of 1.580 to 1.584 in the refractive index in the longitudinal direction X when the label is mounted at an adherend 3. |
