  An adhesive sheet for dicing comprising a base film provided at least one surface thereof with an adhesive layer, wherein the base film comprises an olefinic thermoplastic elastomer comprising propylene and ethylene and/or &agr;-olefin including 4 to 8 carbon atoms as polymerization components, and the peak melting temperature of the olefinic thermoplastic elastomer is 120° C. or more, is free of economical disadvantages with less reduction in the quality level of products and less generation of fibrous off-cuts during dicing. In particular, fibrous off-cuts occur less during dicing when the base film contains a crystal-nucleating agent. Further, generation of chippings during dicing can be prevented by incorporation of an ethylene series polymer into the base film.

  一种用于切割的粘合片，包括至少一表面带有粘合层的基膜，其中基膜包括丙烯和乙烯和/或α-烯烃（4-8个碳原子）作为聚合组分的烯烃热塑性弹性体，且烯烃热塑性弹性体的峰值熔点为120℃或更高，不会产生经济上的不利影响，同时产品质量水平降低和切割过程中纤维碎屑的生成较少。特别是，在基膜中含有结晶成核剂时，切割过程中的纤维碎屑会更少。此外，通过将乙烯系聚合物并入基膜中，可以防止切割过程中产生切屑。
