Embodiment 1

[0184] High-quality paper (thickness 100 μm) laminated with polyethylene was used as the carrier sheet 1, and a polyether-type moisture-permeable polyurethane elastomer solution was coated on the surface of the polyethylene side by a bar coating method so that the dried The thickness was 5 μm, and drying was performed to form a support 2 . The polyether type polyurethane elastomer solution was Seiko Chemicals Co., Ltd.'s trade name "Lack Skin US2268" (Tg = -23.1° C.).

[0185] On one side of the release sheet 4 (polyethylene laminated paper treated with silicone, 10 cm in length, 12 cm in width, and 120 μm in thickness), an acrylic adhesive (acrylic acid 2-ethyl Hexyl hexyl ester / vinyl acetate / acrylic acid=85 / 11 / 4 weight ratio copolymer) in an organic solvent solution so that the thickness after drying was 5 μm, and then dried to form the adhesive layer 3 .

[0186] On the support body 2 side of the laminate composed of the carrier sheet 1 and the support body 2 obtained abov...

Embodiment 2

[0191] The sticking body sheet was produced in the same procedure as in Example 1 except that the pick-up part a was only the carrier sheet 1 (the support body 2, the adhesive layer 3, and the peeling sheet 4 were removed). Table 1 shows the evaluation results of the sticking characteristics of the sticky body sheet.

Abstract

Disclosed is an adhesive sheet comprising a carrier sheet, an adhesive patch, and a release sheet, laminated in that order. In the disclosed adhesive sheet, (a) the adhesive patch comprises two layers, namely a support body and an adhesive layer of the same shape, (b) the carrier sheet is adjacent to the support body of the aforementioned adhesive patch, (c) said adhesive sheet is configured from a grip section and a body part, (d) in the body part, or in the body part and the grip part, the surface area of the release sheet is greater than that of the adhesive patch, (e) the boundary between the grip part and the body part is formed by an incision, and (f) said incision goes through the adhesive patch from the release sheet side, and cuts into the carrier sheet from the adhesive patch side, reaching a depth greater than or equal to 20% but less than 50% of the thickness of said carrier sheet. The disclosed adhesive sheet is formed by arranging in parallel on a release sheet multiple adhesive patches, on which a carrier sheet is laminated. Also disclosed are uses of the aforementioned adhesive sheet for adhesion to the skin surface to prevent direct irritation of an affected area of the skin, or, for adhesion to the face for a cosmetic lift; also disclosed is a method of adhering the aforementioned adhesive sheet.

Description

technical field [0001] The present invention relates to an attached body sheet comprising an adhesive (referring to both the case where the adhesive layer contains a pharmacologically active substance and the case where the adhesive layer does not contain a pharmacologically active substance.), in detail, the present invention It relates to an adhesive sheet that can apply an adhesive agent having a thin support to the surface to be attached, such as the skin, with good one-handed operability and without the adhesive agent coming into contact with the fingers, and which results in less waste when the application is completed. . More preferably, it relates to an attached body sheet comprising an adhesive applied to the skin surface and used to prevent direct scratching of the skin affected part, or a cosmetic adhesive applied to the face and used for lifting Attach body sheet. Background technique [0002] Adhesives used for sticking to the skin surface are usually provided...
