Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a transfer paper for manufacturing partial adhesive sheets, and the object thereof is to easily obtain partial adhesive sheets that have excellent pattern changeability and are easy to work with. An object of the present invention is to provide a transfer paper for producing a partial adhesive sheet that can be used to produce a partial pressure-sensitive adhesive sheet.

Conventionally, as a method for obtaining a partially adhesive sheet, the adhesive is applied partially by silk printing method, or the adhesive is applied onto a roll using Rollco-1, etc., and then the adhesive is This is done by scraping off a portion of the surface.

However, the conventional method described above has the disadvantages of local variations in coating fit, no change in pattern in non-adhesive areas, poor dimensional stability due to drying after coating, and poor workability. There is a processing problem.

As a result of intensive research to improve the above-mentioned conventional drawbacks, the present inventor has found that by using the transfer paper described in the claims, the workability is excellent, and the pattern changeability of the obtained partially adhesive notebook is improved. I was able to easily make an excellent partial adhesive sheet.

That is, in the present invention, a desired pattern is printed on the surface of a base material such as polyethylene coated paper or polyester film, and a part other than the printed pattern is coated with noricorn resin or a non-silicone resin. This is a transfer paper for producing a partial pressure-sensitive adhesive sheet, characterized in that a release agent is coated thereon.

FIG. 1 shows one embodiment of the present invention. Next, the present invention will be explained with reference to an illustrated example.

In the transfer paper 1 of the present invention, a printed layer 3 with a desired pattern is laminated on the surface of a base material 2, and a release agent layer 4 is laminated on the surface portion of the profiteer 1 other than the printed layer 3. There is. The base material 1 for the strings is preferably polyethylene coated paper, polyester film, etc., but is not necessarily limited to these, and composite paper laminated with other plastic films or other plastic films can also be used. .

The printing layer 3 applied on the base material is a printing ink selected from acrylic, rubber, urethane, etc., and has a releasability to the base material 2. Material 2
Furthermore, as the release agent layer 4 to be laminated on the surface of the base material 2, a noricorn resin is suitable. in this case,
The printed layer 3 is formed to have a thickness of 0.5 to 2 μm.

Next, to illustrate the manufacturing method of the present invention, group 4. J 2 On the surface of the base material 1, on which the desired printed part is punched out, that is, after applying the 1iilf type agent using a gravure plate in the negative form of the printed part, the release agent layer 4 is applied. on the entire surface of
Printing ink is applied by gravure plate or roll coating. In this case, the printing ink is repelled and cannot be coated on the part where the release agent layer 4 has been applied, so the printing ink is filled and applied to the part where the desired pattern is brazed and the printing layer 3
can be easily formed. Therefore, the transfer paper of the present invention can achieve printing corresponding to various patterns.

FIG. 2 shows another embodiment of the present invention (in FIG. 2, the same reference numerals as in FIG. 1 are the same parts 4d). 4. An adhesive layer 6 is laminated in advance on the surface of 4. The transfer paper 5 as shown in FIG. 2 has the advantage that the surface of the adhesive layer 6 of the transfer paper 5 can be tacked on as is without the need to apply an adhesive to the partial adhesive sheet, as will be described later.

Next, the case of manufacturing a partial adhesive sheet using the present invention will be explained using the transfer paper 1 shown in FIG. Then apply the adhesive layer 9 and die. Next, the transfer paper 1 shown in FIG. 1 is applied to the surface of the adhesive layer 9 of the partial adhesive sheet 1-7.
After pasting together the surfaces on which the printed layer 3 and the release agent layer 4 are formed, the transfer paper 1 is peeled off from the surface of the partial adhesive sheet 7, as shown in FIG.

When the transfer paper 1 is peeled off as described above, as shown in FIG. Since it has removability with the material 2, it adheres to the adhesive layer 9, and therefore, the base material 2 of the transfer paper 1 is easily peeled off and the printing layer 3 is transferred onto the surface of the adhesive layer 9.

The surface of the printed layer 3 transferred to the adhesive layer 9 does not have the same tackiness, while the adhesive layer 9 on which the printed layer 3 is not transferred
This area develops tackiness, and therefore the obtained product is a sheet having partial tackiness.

In addition, in another embodiment shown in FIG. 2, the partial adhesive notebook is not coated with an equivalent adhesive layer, and the Sogetsu is used as is\transfer paper 5.
The adhesive layer 9 coated on the surface of the adhesive layer 9 may be used for adhesion, resulting in even better workability.

Furthermore, in the present invention, by forming the printed layer 3 into an appropriately shaped stripe, check, etc., the strength of adhesiveness can be appropriately selected, and air pockets can be prevented when laminating the partial adhesive sheet. It can be prevented, has a good appearance when rolled up, and has excellent workability.

As described in "2" above, the present invention is advantageous in that a desired printing layer is formed in advance,
Since the non-printing area is coated in combination with a release agent layer, the printed pattern is highly variable and the adhesive strength can be selected as appropriate. It has the advantage of being easy to work with, since it is possible to obtain a partially adhesive note with a simple operation.
