欠点があつた。 However, when a tape partially formed with a pressure-sensitive adhesive layer or a non-adhesive material layer is wound into a roll like this, the thickness is uneven, so it deforms over time, resulting in a poor product appearance. The disadvantage was that it significantly reduced the
本考案はかかる従来技術の情況に鑑み鋭意検討
の結果考案されたものであり、以下その具体例を
図面を用いて説明する。 The present invention was devised as a result of intensive studies in view of the situation of the prior art, and specific examples thereof will be explained below with reference to the drawings.

is an adhesive treatment layer 3 formed on the entire surface of the support 1.
a pressure-sensitive adhesive layer with a thickness of 10 to 300 μm (for example, composed of a material mainly composed of rubber and/or synthetic resin that has pressure-sensitive adhesive properties at room temperature), 4 is a support A release treatment layer (for example, polyvinyl N-octadecyl carbamate, having a carbon number of 14
It is composed of polyacrylic acid ester copolymer, silicone resin, etc. ).

処理、金属ナトリウム処理などが挙げられる。 The adhesive treatment layers 3a and 3b are formed by chemical or physical treatment such as oxidizing or etching the surface of the support 1, or by applying an undercoat material. Examples include high-voltage electric shock treatment accompanied by corona discharge, chromic acid treatment in sulfuric acid or hot nitric acid, sputter etching treatment, metallic sodium treatment, and the like.

うに設計されていることが必要である。 However, when the tape base constructed as described above is wound into a roll and layered as shown in FIG. Adhesive strength (B) with release treatment layer 4 and adhesive treatment layer 3 partially formed with release treatment layer 4
It is necessary that the design be such that the adhesive force (C) with b satisfies the relationship (A)<(B)<(C).
このように設計したロール状テープを巻き戻す

層２の表面に転着され、部分接着構造が構成され
る。 When the rolled tape thus designed is rewound, the release layer 4' is partially transferred onto the surface of the adhesive layer 2, forming a partially adhesive structure, as shown in FIG.
本考案の接着テープは以上のように構成されて
いるから、巻き戻し前は均一な厚みを有し、経日
における変形がなく、巻き戻しすることによつて
良好な部分接着テープが得られるという特徴を有
する。 Since the adhesive tape of the present invention is constructed as described above, it has a uniform thickness before unwinding, does not deform over time, and by unwinding, a good partial adhesive tape can be obtained. Has characteristics.
