ABSTRACT:
In order to provide heat-sensitive adhesive materials that represent high pressure-sensitive adhesive strength with respect to rough adherends such as cardboards or polyolefin wraps and lower decrease of adhesive strength with time, are thermally activated with lower energy and exhibit excellent blocking resistance, heat-sensitive adhesive materials are disclosed that contain a support, an underlayer, and a heat-sensitive adhesive layer, in this order, wherein the underlayer comprises a thermoplastic resin and a hollow filler, and the glass transition temperature of the thermoplastic resin is −70° C. or higher and below 0° C.
