Example 1: Preparation of the pressure-sensitive transfer tape of the present invention. Preparation of pressure sensitive adhesive

90 g of sodium lauryl sulfate and 2500 g of deionized water were added to a reaction flask equipped with a mechanical stirrer, a condenser and a thermometer. Next, a mixture of 2-ethylhexyl acrylate (800 g), n-butyl acrylate (300 g) and acrylic acid (100 g) was added to the reaction flask and stirred (rotation speed 500 rpm) for 15 minutes to be mixed. Then put 50g of metabisulfite Sodium metabisulfite was placed in the reaction flask and the reaction flask was heated to 40 °C. Thereafter, 20 g of a hydrogen peroxide solution (30%) was added, and the reaction temperature was maintained at 70 ° C for 8 hours. Thereafter, the emulsion of the pressure-sensitive adhesive is obtained by filtration.

Preparation of pressure sensitive transfer tape

A PET substrate having a thickness of 12 μm and coated with a release layer on each side was obtained. An appropriate amount of the pressure sensitive adhesive emulsion is applied to the substrate to form a pressure sensitive adhesive layer. In this embodiment, the pressure-sensitive adhesive layer has a width of about 1 Å.

After applying the pressure sensitive adhesive emulsion to the substrate, the substrate is heated at 100 ° C for about 2 minutes to dry the coating layer on the substrate, thereby obtaining the pressure feeling of the embodiment of the present invention. Transfer the tape. The pressure-sensitive adhesive tape obtained in the present embodiment has a pressure-sensitive adhesive layer having a thickness of 5 μm (hereinafter referred to as "tape-5 μm", and so on).

In the same manner, a pressure-sensitive adhesive layer having a thickness of 10 μm (tape-10 μm), 15 μm (tape-15 μm), 20 μm (tape-20 μm), 25 μm (tape-25 μm) or 30 μm (tape-30 μm) was prepared. Different tapes.

Example 2: Adhesion test of the pressure sensitive transfer tape of the present invention. Use one attenuation rate and use five attenuation rates

In this experiment, the pressure-sensitive transfer tape prepared by the first embodiment and three other different transfer tapes (PLUS SPIN ECO, NICHIBAN tenori and Tombow PIT) were separately tested to obtain the stripping of the tape by the tape. Adhesive force uses a single decay rate and uses five decay rate results. A common feature of the three commercially available transfer tapes is that the pressure sensitive adhesive layer on the tape is completely applied to the substrate without any uncoated areas.

The pressure-sensitive adhesive layer of the tape obtained in the first embodiment and the other three different commercially available transfer tapes were respectively taken into one section, and the fragments were pasted using a 2 kg rubber roller. On different one-side-coated papers. The different single-coated papers were then adhered to a piece of forest paper using a 2 kg rubber roller. Subsequently, the initial peel adhesion of each tape adhesive layer was tested by a tensile tester.

After peeling off the single-sided coated paper, the two-sided coated paper was again adhered to a forest paper using a 2 kg rubber roller, and the peel adhesion of each adhesive layer was tested (ie, the test for peel adhesion was used). Primary decay rate). Next, using a 2 kg rubber roller, repeating the one-side coated paper on a piece of forest paper and peeling off, and then repeating the three times of pasting and peeling, the single-sided coated paper is again adhered to a forest. On the paper, the peel adhesion of each adhesive layer of the tape was tested (ie, the five-time decay rate was used to test the peel adhesion). The results of the initial peel adhesion, the use of a single decay rate, and the use of five decay rates are shown in Table 1 below.

According to the results of the above list 1, three different transfer tapes are commercially available because the pressure-sensitive adhesive layer is completely coated on the substrate, and therefore exhibits a strong initial peel adhesion. In the present invention, the pressure-sensitive adhesive layer of each pressure-sensitive adhesive tape is not completely coated, and therefore the thickness of the pressure-sensitive adhesive layer is a key factor affecting the peel adhesion result. That is to say, the thicker the pressure-sensitive adhesive layer, the stronger the adhesion provided. In order to obtain an initial peel adhesion equivalent to such commercially available tapes, the pressure-sensitive adhesive layer of the pressure-sensitive adhesive tape of the present invention preferably has a thickness of more than 20 μm.

However, the thicker the pressure-sensitive adhesive layer is, the less susceptible the pressure-sensitive adhesive tape has to the displaceable property; the advantages of the present invention can be seen from the use of a single decay rate and the use of five decay rates. Compared with the above-mentioned commercially available products (PLUS SPIN ECO, NICHIBAN tenori and Tombow PIT), the pressure-sensitive transfer tape of the present invention exhibits a comparable peel adhesion (the peel adhesion of some samples of the present invention is even stronger). However, the attenuation rate is significantly better than these commercially available products. That is, the pressure-sensitive adhesive layer of the pressure-sensitive transfer tape of the present invention can not only undergo several shifts but also maintain a desired adhesive force. Therefore, the thickness of the pressure-sensitive adhesive layer is preferably not more than 30 μm in consideration of the displacement demand.

Adhesion retention test

The pressure-sensitive adhesive layer of the pressure-sensitive transfer tape of the present invention and three other commercially available transfer tapes (PLUS SPIN ECO, NICHIBAN tenori, and Tombow PIT) were respectively taken into one section, and each fragment was transferred using a 2 kg rubber roller. To an upper edge surface of a different poster (84 cm x 119 cm; 150 g). In this experiment, each tape segment used was 84 cm x 1 in. The posters are then glued to a clean wall and the individual maintenance time is recorded (ie, the time the poster is dropped from the wall). The recorded test results are shown in Table 2 below.

Table 2: Maintenance time

Based on the results shown in Table 2 above, it can be seen that the posters adhered to the pressure-sensitive adhesive layer of the pressure-sensitive transfer adhesive tape of the present invention maintain the time of sticking to the wall surface longer than the posters adhered to the commercially available adhesive tapes. The thickness of the pressure-sensitive adhesive layer is preferably more than 5 μm in consideration of the adhesive retention performance of the pressure-sensitive adhesive tape.

Therefore, the thickness of the pressure-sensitive adhesive layer is preferably 5 to 30 μm in order to satisfy the requirements of displacement and adhesion retention.

Example 3: Cutting test of different types of pressure sensitive adhesive layers.

Several PET substrates were obtained, each of which had a thickness of 12 μm and a width of 310 mm, and each of which was coated with a release layer. An appropriate amount of the pressure-sensitive adhesive emulsion prepared in the above Example 1 was applied to each substrate in a different pattern to form a pressure-sensitive adhesive layer.

As shown in the sixth drawing, a tape sheet 40, a tape sheet 50, and a tape sheet 60 are obtained, and the pressure-sensitive adhesive layers on the PET substrate of the tape sheets are in different patterns. The pressure-sensitive adhesive on the tape material sheet 40 is completely coated without gaps; the tape material sheet 50 has a plurality of pressure-sensitive adhesive coating tapes having a width of 10 mm, and is coated with two pressure-sensitive adhesives. Between the belts, there is a gap 51 with a width of 2 mm; the strip of adhesive material 60 has a plurality of pressure-sensitive adhesive coating strips having a width of 8 mm, and each of the two pressure-sensitive adhesive coating strips There is a gap 61 between the widths of 4 mm. The thickness of the pressure-sensitive adhesive on the strips 40, 50 and 60 of the tape materials was 15 μm.

Thereafter, the tape sheet 40 was cut to obtain a pressure-sensitive transfer tape having a width of 12 mm, and the width of the pressure-sensitive adhesive layer was also 12 mm. On the other hand, the center of the partitions of the strips 50 and 60 of the strips are respectively cut to obtain a pressure-sensitive transfer tape having a width of 12 mm, wherein the width of the adhesive layer on the strips 50 and 60 of the strips is 10 mm and 8mm, the width of the uncoated tape is 1mm and 2mm respectively. In this way, the pressure-sensitive transfer tape of the present invention as shown in the third figure can be obtained, which has a first uncoated tape, a pressure-sensitive adhesive layer and a second uncoated tape which are disposed in the horizontal direction. .

It must be noted here that the cutter has been adhered by the adhesive during the cutting of the tape sheet 40. In fact, the procedure for cutting the strip of material 40 has been forced to pause several times in order to remove adhesive contaminants on the cutter or to replace the clean cutter so that the cutting process can continue.

On the other hand, when the adhesive-coated tape has a substrate having a spacing of 2 mm, the cutter has been slightly adhered by the adhesive, but the contaminant does not seriously affect the cutting process. Further, when the adhesive-coated tape has a substrate having a gap of 4 mm, only the cutter is contaminated by the adhesive. Therefore, it has been found through experiments that the adhesive coating tape pattern having a spacing of 4 mm is particularly advantageous for the manufacture of pressure-sensitive transfer tape.
