Means for Solving the Problems As a result of intensive studies for solving the above problems, the present inventors have partially formed a thin film layer having a peeling action on one surface of a transparent film substrate. It was found that the above-mentioned problems can be achieved by providing and then printing variable information, and further by coating one of the pressure-sensitive adhesive layer and the heat-sensitive adhesive layer on the side of these layers, and based on this finding The present invention has been completed.

That is, according to the present invention, at least a part of the variable information is printed on one surface of a transparent film substrate on which at least one surface is partially provided with a thin film layer having a peeling action. A variable information printed label is provided by printing variable information as described above, and one of an adhesive layer and a heat-sensitive adhesive layer is further provided on the layer surface side thereof. is there. Hereinafter, the present invention will be described in detail.

The method for producing a variable information printed label of the present invention uses a transparent film substrate as a label substrate.

On one surface of this transparent film substrate, a thin film layer having a peeling action on at least one surface is partially provided. The thin film layer may be transparent enough to allow the variable information to be seen therethrough. The ratio of the area of the thin film layer partially provided on one surface of the transparent film substrate is not particularly limited, but is usually 5 to 90% of the area of one surface of the transparent film substrate, and preferably 10 to 6
It is 0%. This thin film layer may be a layer containing only a release agent having a release action on both sides, or may be a transparent film layer having a release action on only one of the opposing print layer or transparent film substrate.

Examples of the above-mentioned release agent include silicone resin, cellulose resin, alkyd resin, acrylic resin, polyurethane resin, polyester resin and the like, but silicone resin, cellulose resin and acrylic resin are preferable. The method of partially providing the release agent on one surface of the transparent film substrate can be performed by various methods, for example, by applying the release agent,

It is perceived by the viewer by a visual impression that is different from the visual impression of the variable information. This allows the viewer to detect the presence or absence of the peeling history.

Therefore, it is necessary that at least a part of the variable information is printed on the surface of the thin film layer. In addition, it is preferable that part of the variable information is not peeled off because it is easy to distinguish the peeled variable information part and the non-peeled variable information part. Therefore, the printing area of variable information is 3
