の加工を施されて商品となって使用される。Generally, release sheets used for adhesive processing are manufactured by applying a release resin such as silicone resin or polyester resin to the entire surface of a support and drying it. For example, when the adhesive sheet is produced by a transfer method, an adhesive is applied to the release sheet obtained in this way, and after drying, a base sheet such as paper, film, foil, woven fabric, non-woven fabric, etc. is laminated. It is created by tJi. The pressure-sensitive adhesive sheet thus produced is flattened or rolled into an appropriate size and subjected to processing such as printing, overlaying, half-cutting, lees removal, and guillotine, and is then used as a product.

本発明は、粘着剤に対して剥離部と非剥離部とを有する
部分剥離シートを使用するものであって、従来このよう
な部分剥離シートは、市場には全く見当たらない。The present invention uses a partial release sheet that has a release area and a non-release area for an adhesive, and such a partial release sheet has not been found on the market at all.

部と非剥離部とを設けてなる部分剥離シートであること
を特徴とする部分粘着シートである。That is, the present invention provides a pressure-sensitive adhesive sheet consisting of a base sheet, an adhesive, and a release sheet, in which the release sheet is applied to the release surface of a silicone resin layer provided on the entire surface of a support.
It is characterized by a partial release sheet that is partially subjected to corona discharge treatment to partially destroy the release properties of the release surface of the silicone resin layer, and provides a release area and a non-release area for the adhesive. This is a partial adhesive sheet.

ない欠点がある。本発明では、支持体の全面にシリコー
ン樹脂が塗布されているので凹凸の発生は全くない。In order to manufacture a partial release sheet using a conventional method, for example, a gravure roll used for applying silicone resin is engraved to create an engraved part and a non-engraved part, and the silicone resin is applied using the gravure roll. Manufacturing methods can be considered. However, when glassine paper is used as a support for a release sheet, if silicone resin is partially applied using a gravure roll, it is necessary to apply curl prevention treatment to the back side of the glassine paper after applying the silicone resin to the cloth. There is a difference in the amount of anti-curl liquid absorbed between the resin coated area and the uncoated area, making it difficult to finish both the silicone resin coated area and the uncoated area flat at the same time.
The disadvantage is that the partially released sheet has unevenness and cannot be used. In the present invention, since the entire surface of the support is coated with silicone resin, no unevenness occurs at all.

Further, a polymer film such as polyethylene, polypropylene, or polyester can be used as the support.

施すことにより、粘着剤に対して剥離部と非剥離部とを
有する部分剥離シートを使用するものである。In the present invention, by partially subjecting the release surface of the silicone resin layer of such a silicone resin release sheet to a corona discharge treatment, a partial release sheet having a release area and a non-release area for the adhesive is used. It is something to do.

ン樹脂層の剥離面はコロナ放電処理される。Corona discharge occurs between an insulated metal electrode and a grounded H
This is generated by applying a high voltage between the silicone resin release sheet and the dielectric roll.By passing the silicone resin release sheet through the interlock between the metal electrode and the dielectric roll, the release surface of the silicone resin layer is exposed to corona discharge. It is processed.

あり、本発明では、いづれの電極であってもよい。There are two types of fi poles: a variable type that can change the length of the electrode when the width of the silicone resin release sheet changes, and a fixed length type that is used when the width is constant. There are electrodes in one row and electrodes in multiple rows of two or more, and in the present invention, any of the electrodes may be used.

適宜長さ分を削って除去しておけばよい。The electrode used in the present invention has a part that emits corona discharge and a part that does not discharge corona, and when using a variable electrode, attach the electrodes of the required length to the electrode set rod at intervals. That's fine. The width of the electrode can be set so as to obtain the desired width. Further, in the case of a fixed electrode, the electrode may be removed by cutting an appropriate length so as to obtain a portion that does not cause corona discharge.

り容易に変えることが出来る。By partially subjecting the silicone resin release sheet to corona discharge treatment in the manner described above, a partial release sheet can be obtained. That is, the part of the silicone resin release sheet that has been subjected to the corona discharge treatment has the releasability of the silicone resin destroyed, and when an adhesive is applied thereto, it cannot be easily peeled off and adheres to the part. In addition, the original releasability of the silicone resin is maintained in the area that is not subjected to the corona discharge treatment, and when an adhesive is applied, it can be easily peeled off. In such a partially peelable sheet, the width and interval between the peeled portion and the non-peeled λ1 portion can be easily changed by selecting electrodes.
