る効果が低下する。The present invention will be described in more detail below. As the plastic film used in the present invention, polyethylene, polyolefin films such as polypropylene,
Examples of the film or sheet include polyester, polystyrene, polyvinyl chloride, polyvinyl chloride, polyvinylidene chloride, polyvinyl acetate, polyurethane, polyamide, Teflon, natural rubber, synthetic rubber, and the like, among which strength when thinned, and A polyester film having an excellent barrier property is particularly suitable. Furthermore, in order to increase the flexibility of the adhesive tape and improve the adhesion to the adherend, and to reduce the discomfort when it is applied to the skin when used for medical purposes, the polyester film is preferably thin and porous. Depending on the type, a thickness of 5 μm or less is preferable. On the other hand, as the porous body, for example, wood pulp, hemp, honey,
Examples include natural fibers such as grooves and chemical fibers such as rayon, vinylon, polyester, nylon, polyphenylene sulphite, acrylonitrile, etc., either alone or mixed and formed into a dry or wet sheet. However, it is preferable to use polyester fibers from the viewpoint of chemical resistance to adhesives and pressure sensitive adhesives, strength and the like. When an adhesive is applied to the porous body side to form an adhesive tape, the thickness of the porous body is 20 μm or more in order to enhance the anchoring property of the adhesive to the porous body.
Air permeability at 6-6.27.1 is 100-300 cm
It is preferably 3 / cm 2 / sec. If the thickness of the porous body is less than 20 μm, the anchoring property of the pressure-sensitive adhesive to the porous body becomes weak when the amount of the adhesive adhered increases. On the other hand, when the air permeability is less than 100 cm 3 / cm 2 / sec, the penetration of the pressure-sensitive adhesive into the porous body becomes poor and the effect of supporting the pressure-sensitive adhesive becomes low. When the air permeability is higher than 300 cm 3 / cm 2 / sec, the pressure-sensitive adhesive can penetrate into the porous body well, but the anchoring effect is weakened and the effect of supporting the pressure-sensitive adhesive is reduced.

る。In the present invention, the above film and the porous body are laminated with an adhesive.
For example, polyester resin, polyvinyl acetate resin,
Examples include ethylene-vinyl acetate-based resins, polyacrylic acid ester-based resins, vinyl chloride-vinyl acetate copolymer resins, etc., but when polyester-based ones are used as the porous material, the polyester-based resins have good adhesiveness. Particularly preferred. As a method for laminating the film and the porous body via an adhesive, for example, a so-called wet laminating method in which an adhesive solution is applied to the film and / or the porous body, they are superposed before the solvent evaporates, and then dried. Alternatively, a so-called dry laminating method in which an adhesive is applied to the film and / or the porous body, dried and then laminated by hot pressing can be applied. The obtained base material is JIS
The rigidity at -L1096-6.20.1 is required to be 10 mg or less, and when it is more than 10 mg, the flexibility of the pressure-sensitive adhesive tape becomes poor and the adhesion to an adherend is poor. The present invention can also be provided with a silicone coating layer on the non-laminated surface of the film, but as the present method, for example, a silicone oil is diluted to an arbitrary concentration, and a usual bar coater, gravure coater, roll coater, etc. A method of applying by a coating method can be mentioned. As for the coating amount of silicone, since it is coated on the film layer having a high barrier property, even a small amount can exert its effect,
0.003 to 0.3 g / 〓 is suitable. If it is less than this range, the effect of slipperiness is not exhibited, and if it is more than this range, there is an adverse effect such as transfer to another surface. In order to process the adhesive tape using the substrate of the present invention, a known method may be used, for example, an arbitrary adhesive is applied to the porous body side of the substrate and, if necessary, a porous body layer of the adhesive is formed. It is processed by applying pressure, etc. to increase the penetration of the and the anchoring property. Further, it is optional to apply the pressure-sensitive adhesive to the non-laminated surface of the film instead of the porous body side, but adhesive residue of the pressure-sensitive adhesive is likely to occur.

め、粘着剤を担持する効果が低下する。On the other hand, as the porous material, for example, natural fibers such as wood pulp, hemp, honey bees, and groats, or chemical fibers such as rayon, vinylon, polyester, nylon, polyphenylene sulphite, acrylonitrile, etc. are used alone. Alternatively, they may be mixed and formed into a sheet form by a dry method or a wet method, and among them, a polyester fiber is preferable from the viewpoint of chemical resistance to adhesives, pressure-sensitive adhesives, etc. and strength. When a pressure-sensitive adhesive tape is formed by applying a pressure-sensitive adhesive to the porous body side, the thickness of the porous body should be 20 μm or more in order to enhance the anchoring property of the pressure-sensitive adhesive to the porous body.
The air permeability in IS-L1096-6.27.1 is 10
It is preferably from 0 to 300 cm 3 / cm 2 / sec. If the thickness of the porous body is less than 20 μm, the anchoring property of the pressure-sensitive adhesive to the porous body becomes weak when the amount of the adhesive adhered increases. The air permeability is 100 cm 3 / cm 2 / se
If it is less than c, the penetration of the pressure-sensitive adhesive into the porous body becomes poor,
The effect of supporting the adhesive becomes low. Air permeability is 300 cm
When it exceeds 3 / cm 2 / sec, the penetration of the pressure-sensitive adhesive into the porous body is improved, but the anchoring effect is weakened, and the effect of supporting the pressure-sensitive adhesive is reduced.

へ転移するなどの弊害がでてくる。As a method of laminating the film and the porous body with an adhesive, for example, an adhesive solution is applied to the film and / or the porous body, the films are superposed before the solvent is evaporated, and then dried. A wet laminating method or a so-called dry laminating method in which an adhesive is applied to a film and / or a porous body, dried and then laminated by hot pressing can be applied. The obtained substrate is
The rigidity according to JIS-L1096-6.20.1 is 10
It is necessary to be less than or equal to mg, and if it is more than this, the flexibility when formed into an adhesive tape is poor and the adhesion to an adherend is poor. The present invention can also be provided with a silicone coating layer on the non-laminated surface of the film, but as the present method, for example, silicone oil is diluted to an arbitrary concentration,
Bar coater, gravure coater, roll coater, etc.
A method of applying by a normal application method can be mentioned. As the coating amount of silicone, since it is coated on the film layer having a high barrier property, the effect can be exhibited even with a small amount, and 0.003 to 0.3 g / m 2 is preferable. If it is less than this range, the effect of slipperiness is not exhibited, and if it is more than this range, there is an adverse effect such as transfer to another surface.

あるが、粘着剤の糊残りが生じやすくなる。A known method may be used for processing the pressure-sensitive adhesive tape using the base material of the present invention. For example, an arbitrary pressure-sensitive adhesive may be applied to the porous body side of the base material, and if necessary, the pressure-sensitive adhesive may be porous. It is processed by applying pressure in order to increase the penetration into the body layer and to further improve the anchoring property. Further, it is optional to apply the pressure-sensitive adhesive to the non-laminated surface of the film instead of the porous body side, but adhesive residue of the pressure-sensitive adhesive is likely to occur.
