Definitions

  • the present invention has a high degree of biomass, has sufficient adhesive strength, and applies an adhesive tape for a long period of time in a high temperature environment (about 85 ° C or higher) or a high temperature / high humidity environment (about 60 ° C or higher, about 90% or higher). It is possible to provide an adhesive tape having excellent disassembly after use.
  • non-woven fabric base material examples include non-woven fabrics obtained by using chemical fibers such as Manila hemp, wood pulp, rayon, acetate fiber, polyester fiber, vinylon fiber (polyvinyl alcohol fiber), polyamide fiber, and a mixture thereof. Be done. Above all, it is more preferable to use a non-woven fabric produced by using 50% or more of a plant-derived raw material.
  • Example 2 With the same composition as in Example 4, only the cross-linking agent was changed to 2.9 parts by weight and blended to obtain a pressure-sensitive adhesive having a gel fraction of 45% by weight. Next, a double-sided adhesive tape was obtained in the same procedure as in Example 1. Then, the double-sided adhesive tape was subjected to an evaluation test on adhesive strength and easy disassembly. The details of the evaluation results are shown in Table 2.
