The continuous self-adhesive label includes: a belt-like label base material 2; a self-adhesive adhesive layer 3 provided on a back surface side of the label base material 2; the heat-sensitive coloring agent layer 11 provided on the front surface of the label base material 2; a release agent layer 12 provided on the heat-sensitive coloring agent layer 11; and cutting lines 4 for separation that allow single self-adhesive label 13 to be formed with predetermined label pitches, and that are provided on the label base material 2.

Description

    The present invention relates to a self-adhesive label continuous body and a self-adhesive label, and particularly a self-adhesive label continuous having adhesive properties to each other but difficult to adhere to other members such as general paper materials and film materials. It relates to body and self-adhesive labels.

A conventional self-adhesive label continuum and self-adhesive label will be outlined based on FIGS.
FIG. 7 is a cross-sectional view of a conventional self-adhesive label continuous body 1, and the self-adhesive label continuous body 1 includes a strip-shaped label base material 2 and a self-adhesive adhesive layer provided on the back side of the label base material 2. 3.

    The label substrate 2 is made of kraft paper, high-quality paper, other arbitrary paper material or synthetic resin material having a relatively rough surface, and forms a cutting line 4 for separation by a perforation or the like to form a predetermined label. A single-leaf self-adhesive label 5 can be formed at a pitch.

The self-adhesive adhesive of the self-adhesive adhesive layer 3 adheres firmly to each other when the surfaces of the self-adhesive adhesive layer 3 are contact-pressed, but if it is forcibly removed, the self-adhesive adhesive layer 3 itself While the self-adhesive label continuous body 1 (self-adhesive label 5) is peeled off from the back side, it has a characteristic that it is difficult to adhere even if the self-adhesive adhesive layer 3 is pressed against another member.
Therefore, a label having a general pressure-sensitive adhesive layer requires a release paper (mounting paper) for its backing, but does not require the release paper itself, which saves resources and reduces the burden on the environment. There is an advantage of less.

    Arbitrary display information, for example, fixed information 6 such as “settled” is printed in advance on the front side of the self-adhesive label 5.

When using the self-adhesive label continuous body 1 having such a configuration, the self-adhesive label 5 is separated and separated at the separation cutting line 4 and attached to an arbitrary article.
For example, FIG. 8 is a perspective view showing an example in which the self-attached label 5 is attached to the handle 8 of the my basket 7 that the purchaser brings to the retail store such as a supermarket.
As shown in the figure, when the self-adhesive label 5 is hung around the handle 8 and the self-adhesive adhesive layer 3 of the self-adhesive label 5, that is, the back surfaces are aligned and lightly pressed, the self-adhesive label 5 itself is ring-shaped on the handle 8. For example, fixed information 6 such as “settled” can be displayed to indicate that the payment settlement for the purchased item 9 in my basket 7 has been completed.

However, since the self-adhesive adhesive layer 3 of the self-adhesive label continuous body 1 (self-adhesive label 5) as described above is not adhesive, the self-adhesive label continuous body 1 has a roll shape. In other words, it is difficult to mechanically roll it out into a desired printer (not shown) and to feed it out in a strip shape. Therefore, there is a problem that there is a problem in thermal transfer printing on the surface side of the label substrate 2. Although it is conceivable to use thermal paper for the label base material 2, the surface of the thermal paper has a high smoothness, so that there is a problem of causing a problem of blocking with the self-adhesive adhesive layer 3.
That is, during the manufacturing process of the self-adhesive label continuous body 1, the fixed information 6 is printed and displayed in advance on the front surface side of the label base material 2 before the self-adhesive adhesive layer 3 is applied to the back surface side of the label base material 2. However, there is a problem that it is difficult to display information necessary at a retail store or other sites as variable information on an ad hoc basis.
In other words, the information that can be displayed on the self-attached label 5 is limited to simple advertisement information set in advance or fixed information such as a design, and there is a problem that the field of use is narrow.
