JPH09106253A - Continuous strip of thermal labels without backing paper - Google Patents

Abstract

PROBLEM TO BE SOLVED: To smooth the let-off and transfer of labels by applying a release agent on the front surface side of a band-shaped thermal label base material and continuously or non-continuously forming the fine regions of tacky adhesive parts and non-tacky adhesive parts on the rear surface side thereof. SOLUTION: A release material layer 3 consisting of silicone, etc., is applied on the front surface side of the thermal label base material 2 of the band-shaped thermosensitive colorable label 1 and the pressure sensitive tacky adhesive layer 4 applied over the entire surface is applied on the rear surface side of this thermal label base material 2. Next, non-tacky adhesives 6, such as UV ink and UV varnish, are formed to a mesh form by a meshed roller or graver roller on the front surface of the pressure sensitive tacky adhesive layer 4. Then, the surface thereof exhibits halftone rugged shapes and the recessed thereof are indicated by a code 5. The non-tacky adhesives 6 are held embedded into these recesses 5. The pressure sensitive tacky adhesive layer 4 thereof has a partly projecting state and has weakly tacky adhesive power and, therefore, the stripping resistance in letting-off is good and the transfer of the labels is smoothed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermal label continuous body without a mount, which is used by being set in a roll shape in a label printer, an automatic label sticking machine or the like.

[0002]

2. Description of the Related Art In a pressure-sensitive label continuous body without a backing sheet, since there is no strip-like backing sheet on the back surface of the label as in the conventional case and a pressure-sensitive adhesive is applied to the back surface of the label, it is wound in a roll shape. When rotated, the adhesive surface comes into contact with the surface of the label, and has a defect that it is not smooth even when it is delivered (peeled) and transferred inside the device.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art and to provide a thermal label continuous body without a backing sheet, which makes it possible to smoothly feed and transfer the label.

[0004]

In the thermal label continuum without a mount of the present invention, a release agent layer 3 is applied to the surface side of a belt-shaped thermal label substrate 2, and an adhesive portion 4 is applied to the back side thereof. The thin area of the non-adhesive portion 6 is formed continuously or discontinuously.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The heat-sensitive thermal label without a mount of the present invention will be described with reference to FIG. 1 shown as a back view thereof, FIG. 2 which is a partial perspective view thereof and FIG. 3 which is a sectional view.
The thermosensitive color-developing label 1 to which the mesh-shaped non-adhesive 6 shown in FIG. 1 is applied is wound in a roll shape with the back side thereof as the inside. With particular reference to FIG. 3, a belt-shaped thermosensitive color-developing label 1
A release material layer 3 made of silicon or the like is applied to the front surface side of the thermal label base material 2, and a pressure sensitive adhesive layer 4 applied over the entire surface is provided on the back surface side of the thermal label base material 2.

Next, a non-adhesive agent 6 such as UV ink or UV varnish is formed on the surface of the pressure-sensitive adhesive layer 4 in a mesh shape with a mesh roller and a gravure roller. Therefore, this surface has a concavo-convex pattern of halftone dots as shown in FIGS.
Reference numeral 5 denotes a recess, in which the non-adhesive 6 is in a buried state, and a part of the pressure-sensitive adhesive layer 4 is in a protruding state, so that it has a weak adhesive force.

Further, the non-adhesive agent 6 may be applied on the entire surface, and in this case, by applying a thin coating, it is possible to obtain a weak adhesive property as described above.

[0008]

As described above, according to the present invention, the release agent layer 3 is formed on the surface of the band-shaped thermal label substrate 2, and the thin areas of the adhesive portion 4 and the non-adhesive portion 6 are continuously or non-existent on the back surface thereof. Since it is formed continuously, its adhesive force can be weakened. Therefore, there is an advantage that the thermal label continuum without a mount is excellent in peeling property when it is fed out from the rolled state and the label is smoothly transferred inside the device.
