するものである。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a splicing tape for photographic development. More specifically, in a system for performing photographic development in a short time, a negative film and a lead film are spliced. The present invention provides a splicing tape for photographic development, which prevents the negative film from fogging in a cartridge.

脂を主体とする粘着性物質層を設けたことにある。The present invention provides a novel splicing tape for photographic development that solves the drawbacks of the prior art. The gist of the present invention is to add 0.1 to 50 parts by weight of a light-shielding agent to 100 parts by weight of plastic. And at least 2
The light transmittance in the visible light region is 20 at a thickness of 5 μm.
The adhesive layer mainly composed of rubber and / or synthetic resin is provided on the surface of the tape support having a percentage of not more than%.
以下図面を本考案の実例を具体的に説明する。 An example of the present invention will be specifically described below with reference to the drawings.

類等が選択される。In FIG. 1, 1 indicates a light transmittance of 20 in the visible light region.
% Of the tape support, the support 1 comprises a thermoplastic such as polyester, polyolefin, polyvinyl chloride, polyethersulfone, or polycarbonate, and a light-shielding agent such as a pigment and / or a dye, and a plastic.
It is prepared by mixing 0.1 to 50 parts by weight of a light-shielding agent with respect to 100 parts by weight and forming a film having a thickness of 25 to 100 μm. That is, the type of the light-shielding agent or the like is selected so that the support 1 has a light transmittance of 20% or less in the visible light region in a thickness of at least 25 μm.

には支持体１と同様に遮光剤を配合することができる。On the surface of the tape support 1 thus constructed, the adhesive substance layer 2 mainly composed of rubber and / or synthetic resin is formed by a conventional method in a thickness range of 5 to 50 μm. Material layer 2
A light-shielding agent can be blended in the same as in the support 1.
物質層２は天然ゴム、合成ゴムなどのゴム類と接着性付

る。Since the novel splicing tape for photographic development of the present invention is constructed as described above, even if it is rewound after splicing using this tape as shown in FIG. Since the light transmittance in the visible light region is 20% or less, it has a feature that the inner negative film is not exposed. Further, the support is composed of plastic and a light-shielding agent, and has a light transmittance of 20% or less in the visible light region with a thickness of at least 25 μm, so the desired splicing effect (adhesive strength to both films ) And the certainty of shading.
