The tape was produced using the obtained pressure-sensitive adhesive. . "Adhesive strength and re-peelability of the resulting tape. The results of these evaluations are shown in Table 94. 94856.doc -29. Comparative Example In this example, $ h η + A used in Example 3 is used. In the same way, the polyglycolic sensitization is obtained, but the abbreviated number of the hexagram is used instead of the 0.6 weight of the aromatic amine mixture. The θ system is used for the transmission. The polydecyloxy pressure-sensitive adhesive was used to obtain the strength. The strength and re-peelability of the obtained tape were evaluated. The results of the evaluations are shown in Table 3.
