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.

Abstract
L'invention concerne un ruban adhésif qui présente un niveau élevé de biomasse et une force d'adhérence suffisante et qui est extrêmement facile à éliminer. Ce ruban adhésif comporte une couche d'agent adhésif contenant une résine de polyester et est caractérisé en ce qu'il présente un niveau de biomasse d'au moins 80 % en poids dans la couche d'agent adhésif, un pourcentage de gel inférieur à 40 % en poids dans la couche d'agent adhésif et une force d'adhérence à une tôle d'acier inoxydable de 4 à 15 N/20 mm. La présente invention permet de produire un ruban adhésif qui présente un niveau élevé de biomasse, une force d'adhérence suffisante et qui est extrêmement facile à éliminer après avoir été utilisé pendant une longue période dans des conditions de température ou d'humidité élevées.
