A substrate 2 having provided in a pressure-sensitive adhesive layer 3 side thereof recesses 21 that continue as far as side edges of the substrate 2, and a pressure-sensitive adhesive layer 3 in which are formed a plurality of penetrating passages 31 that penetrate through the pressure-sensitive adhesive layer 3 in a thickness direction are laminated together such that the recesses 21 in the substrate 2 and the penetrating passages 31 in the pressure-sensitive adhesive layer 3 communicate with one another, thus obtaining a pressure-sensitive adhesive sheet 1. According to this pressure-sensitive adhesive sheet 1, air entrapment and blistering can be prevented or eliminated while securing adequate adhesive strength and with no marring of the appearance of the pressure-sensitive adhesive sheet.

In a process for recording into a rewritable recording medium of a non-contact type, when adjacent lines or adjacent overlapping lines are drawn by scanning the medium having a reversible heat sensitive color developing layer on a substrate with laser light and a second line 2 is drawn after a first line 1 is drawn, the time between the start of drawing 1 and the end of drawing 2 and/or the width of the overlapped portion r is controlled as the means for suppressing discoloration of the recorded lines by interference between heat remaining after 1 has been drawn and heat generated while 2 is drawn. When characters, bar codes, solid images or figures are drawn into a rewritable recording medium of the non-contact type by scanning with laser light, excellent readability and visibility of the bar codes can be obtained in recording a plurality of line elements.
摘要:
A method for using a rewritable thermal label of the non-contact type which comprises recording and erasing information repeatedly in accordance with a non-contact method on a rewitable thermal label which remains attached to an adherend. The label contains (a) an anchor coat layer comprising a crosslinked resin, (b) a heat-sensitive color development layer, (c) a light absorption and a photo-thermal conversion layer and (d) an adhesive layer. The layers (a), (b), (c) and (d) are laminated on a first face of a substrate successively. The anchor coat layer is placed next to the substrate. The layer (c) is an outermost layer. The adhesive layer is placed on a second face of the substrate.

There are disclosed a pressure-sensitive adhesive sheet which comprises a substrate sheet, a pressure-sensitive adhesive layer formed on one side of the substrate sheet and a release layer comprising a cured product from an ionizing radiation-curing type releasable resin formed on the other side of the substrate sheet; and a laminate which comprises a plurality of these pressure-sensitive adhesive sheets that are superimposed on one another so that the pressure-sensitive adhesive layer and the release layer directly face each other and the whole surfaces of the pressure-sensitive adhesive layers are covered with the release layers. The above pressure-sensitive adhesive sheets and the laminate formed therefrom can be produced with good workability with a simplified apparatus without the generation of curls, and thus are well suited for use as display labels etc.

摘要:
A recording medium and a recording method are provided which, in a printer comprising a recording head for performing recording without contact with a recording medium and means for changing the carrying direction of the recording medium, can effectively prevent contact of a recording medium with a recording head. The recording medium comprises: a recording sheet; an adhesive layer provided on one side of the recording sheet; and a release sheet provided on the adhesive layer, the recording medium having a Gurley stiffness of 200 to 1500 mgf, the adhesive layer comprising a crosslinked acrylic polymer, the recording medium being such that, in a holding power test according to JIS-Z-0237, the time taken for causing a test piece of the recording medium to drop from an adherend is 500 min or more, or when the time taken for causing a test piece of the recording medium to drop from an adherend is less than 500 min, the test piece drops as a result of coming off at the interface between the adherend and the adhesive layer.
