A pressure-sensitive adhesive tape comprising a support and an adhesive layer or adhesive layers made of an adhesive agent comprising a base polymer and crosslinking agents on a single surface of the support or on the surface and the other surface thereof, characterized in that the support comprises soft polyvinyl chloride comprising a plasticizer, and at least the adhesive agent on the single surface comprises, as a base polymer, an acrylic copolymer having a carboxyl group and further comprises, as the crosslinking agents, an isocyanate type crosslinking agent, a glycidylamine type crosslinking agent, and a melamine type crosslinking agent. This is a pressure-sensitive adhesive tape which uses soft polyvinyl chloride containing a plasticizer as its support, which can satisfy contradictory properties of initial adhesiveness and adhesive force stable over time, and which has no problems about surface contamination.
