    摘要： The pressure-sensitive adhesive sheet for surface protection has a three-layered film formed by laminating a layer A, a layer B and a layer C in this order and a pressure-sensitive adhesive layer formed on the layer C; wherein the layer A contains a polyethylene in an amount of at least 60% by weight based on a total weight of the layer A; the layer B contains a polypropylene type polymer in an amount of at least 50% by weight of based on a total weight of the layer B; and the layer C contains a hydrogenated styrene/diene type hydrocarbon copolymer in an amount of at least 10% by weight based on the total weight of the layer C. This sheet has excellent weathering resistance to undergo neither chalking nor fracture in the substrate at peeling, even after a prolonged outdoor exposure, develops less corona odor to enable extended operation of applying it, and can be manufactured inexpensively with reduced manufacturing process, since no anchor coat treating procedure is required.

    摘要翻译： 用于表面保护的压敏粘合片具有通过层叠层A，层B和层C以及形成在层C上的压敏粘合剂层而形成的三层膜; 其中层A含有基于层A的总重量至少60重量％的量的聚乙烯; 层B含有基于层B的总重量的至少50重量％的聚丙烯类聚合物; 并且层C含有基于层C的总重量至少为10重量％的氢化苯乙烯/二烯烃类共聚物。该片材具有优异的耐候性，在剥离时不会在基材中发生粉化和断裂 即使经过长时间的室外曝光，也会产生较少的电晕气味，从而能够延长使用时的操作，并且由于不需要锚固涂层处理程序，所以可以以较低的制造工艺廉价地制造。
