Abstract

A pressure-sensitive adhesive tape suitable for component cutting process is provided. The pressure-sensitive adhesive tape includes a release film layer, an adhesive layer, and a support base layer that are stacked in sequence. Based on the adhesive layer having a total weight percent of 100 wt %, the adhesive layer includes 40-50 wt % of an acrylic resin, 40-65 wt % of an epoxy monomer, 0.05-0.5 wt % of a hardener, and 0.5-1.0 wt % of an initiator. The adhesive layer has a first acid value before being exposed to an ultraviolet light, the adhesive layer has a second acid value after being exposed to the ultraviolet light, and the second acid value is smaller than the first acid value.
