A pressure-sensitive adhesive tape

摘要

The invention provided an adhesive tape that can satisfy the contradictory characteristics of an initial adhesive property and adhesive force that is stable with time and does not have problems related to surface contamination in the adhesive tape using soft polyvinyl chloride containing plasticizer as a support. The adhesive tape has an adhesive layer that is formed on one surface or both the surfaces of the support by the adhesive containing base polymer, and a cross-linking agent. The support contains soft polyvinyl chloride containing plasticizer, the adhesive on at least one surface contains acryl-based polymerization polymer having a carboxyl group as the base polymer. The adhesive tape contains an isocyanate-based cross-linking agent as a cross-linking agent, a glycidylamine-based cross-linking agent, and a melamine-based cross-linking agent.
