    摘要： A sheet for protecting paint films of automobiles which can prevent the paint film of automobiles from suffering from damages such as discoloration and denaturation even if rainwater or washer penetrates into the gap between the adhesive cover and the paint film while achieving excellent protection function to suspended matters, colliding matters, etc. inherent to protecting sheets and being easily peeled off and removed after completion of the desired protection. The sheet for protecting paint films of automobiles comprises a pressure-sensitive adhesive layer having a roughened surface provided on a substrate made of fiber sheet. Even when rainwater, washer, etc. penetrates into the gap between the pressure-sensitive adhesive layer and the paint film of automobiles from wrinkles formed thereon, the liquid diffuses by capillary action through the gap developed by the roughened pressure-sensitive adhesive layer, making it possible to avoid the residence and concentration of the penetrated dirty water and hence prevent the occurrence of damages such as discoloration and denaturation of the paint film. Further, the arrangement of a pressure-sensitive adhesive layer having a roughened surface reflecting the fiber constituting the protecting sheet, particularly a fibrous continuous roughened surface, makes it possible to further diffuse the contaminating dirty water and hence further avoid the retention and concentration of the penetrated dirty water. Thus, the damages on the paint film can be more securely prevented.

    摘要翻译： 一种用于保护汽车漆膜的片材，即使雨水或垫片渗透到胶粘剂盖和漆膜之间的间隙中也能够防止汽车漆膜遭受损坏，例如变色和变性，同时对悬浮物实现优异的保护功能 ，碰撞物等，以保护片材，并在完成所需保护之后容易地剥离和除去。 用于保护汽车漆膜的片材包括设置在由纤维片制成的基材上的具有粗糙表面的压敏粘合剂层。 即使雨水，洗涤器等渗透到压敏粘合剂层和汽车漆膜之间的间隙中，由于毛孔作用而通过由粗糙化的压敏粘合剂层形成的间隙而扩散， 可以避免渗透的脏水的滞留和浓缩，从而防止出现诸如漆膜的变色和变性的损害。 此外，具有反映构成保护片的纤维的粗糙表面的压敏粘合剂层的布置，特别是纤维连续粗糙化表面，使得可以进一步扩散污染的污水，因此进一步避免了保留和保留 渗透脏水。 因此，可以更可靠地防止漆膜上的损伤。
