PRESSURE SENSITIVE ADHESIVE SHEET AND PROCESS FOR PRODUCING THE SAME |
摘要 |
<p>A substrate 2 having provided in a pressure-sensitive adhesive layer 3 side thereof recesses 21 that continue as far as side edges of the substrate 2, and a pressure-sensitive adhesive layer 3 in which are formed a plurality of penetrating passages 31 that penetrate through the pressure-sensitive adhesive layer 3 in a thickness direction are laminated together such that the recesses 21 in the substrate 2 and the penetrating passages 31 in the pressure-sensitive adhesive layer 3 communicate with one another, thus obtaining a pressure-sensitive adhesive sheet 1. According to this pressure-sensitive adhesive sheet 1, air entrapment and blistering can be prevented or eliminated while securing adequate adhesive strength and with no marring of the appearance of the pressure-sensitive adhesive sheet.</p> |
