A heat-sensitive adhesive material contains a substrate and a heat-sensitive adhesive layer that contains a thermoplastic resin and a solid plasticizer, and the heat-sensitive adhesive material is so configured as to be heated and applied to an adherend, wherein the heat-sensitive adhesive material exhibits such an adhesive strength to the adherend as to increase with time from immediately after applying the heat-sensitive adhesive material to the adherend.

Heat-sensitive adhesive material, adhered article, process and apparatus for thermally activating the heat-sensitive adhesive material

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 &#x2212;70&#xb0; C. or higher and below 0&#xb0; C.

Heat-sensitive adhesive material

A heat-sensitive adhesive material includes a substrate, a heat-sensitive adhesive layer containing a thermoplastic resin and a solid plasticizer formed on the substrate, and a heat-fusible substance capable of depressing the solidifying point of the solid plasticizer in at least one of the heat-sensitive adhesive layer and a layer adjacent to the heat-sensitive adhesive layer. The heat-fusible substance satisfies the following condition (A): E&#x3c;Ewhere Eis heat energy to fuse the solid plasticizer; and Eis heat energy to fuse the heat-fusible substance.

A method for issuing a label, including feeding a first label sheet including a support and a thermosensitive adhesive layer located overlying one side of the support, wherein the first label sheet has a timing mark on the thermosensitive adhesive layer; detecting the timing mark; and cutting or semi-cutting the first label sheet to produce a second label sheet, wherein the timing mark is present at a position other than corners of the second label sheet, and wherein a ratio of an area of the timing mark to an area of the second label sheet is from 0.5 to 35%.
