粘合片
摘要：
本发明提供具备遮光性优异的粘合剂层的粘合片。提供一种粘合片，其具备：包含粘合性聚合物的粘合剂层。在前述粘合剂层中分散有炭黑颗粒。此外，分散在前述粘合剂层内的前述炭黑颗粒的平均粒径为300nm以下。这里，前述平均粒径为由基于TEM观察得到的个数基准的粒径分布求出的平均粒径。
摘要（英）：

The invention provides a PSA sheet having a PSA layer exhibiting superior light shielding. Provided is a PSA sheet comprising a PSA layer that includes a PSA polymer. Carbon black particles are dispersed in the PSA layer. The average particle size of the carbon black particles dispersed in the PSA layer is 300 nm or smaller. The average particle size is an average particle size determined on the basis of a number-based particle size distribution by TEM observation.
