Description of the Related Art Conventionally, a large number of adhesive tapes have been known, and the mainstream is an adhesive (a solution formed on a base material such as kraft paper, cloth, polyester film, polyolefin film, or soft vinyl chloride film). (Including the composition) and then dried. However, in recent years, due to safety, health and environmental problems, the desolvation has progressed, and the pressure-sensitive adhesive tape using a water-dispersed pressure-sensitive adhesive has been shifted. An acrylic ester copolymer or the like is used as such a water-dispersed pressure-sensitive adhesive.

る。Such an acrylic pressure-sensitive adhesive is coated on a polyolefin resin substrate, dried and molded. However, since the anchoring force (anchor force) between the acrylic pressure-sensitive adhesive and the polyolefin resin substrate is weak, the pressure-sensitive adhesive and the substrate often peel off as they are. Therefore, conventionally, a corona treatment has been performed on the surface of the polyolefin substrate on which the pressure-sensitive adhesive layer is to be formed, and a pretreatment such as increasing the anchoring force by providing a polar group on the surface has been performed.

An object of the present invention is to provide a pressure-sensitive adhesive tape having excellent anchoring properties between a substrate and a pressure-sensitive adhesive without performing such corona treatment.
