And the convex part 12 of the carrier 5 is hold | gripped and the carrier 5 is peeled off from the tape main body 2, and sticking of the tape main body 2 is completed.

  Thereby, when the tape main body 2 is affixed, it becomes possible to cut ultraviolet rays from 280 nm to 380 nm. At the same time, the material of the tape body 2 is made of polyurethane, and the thickness of the tape body 2 is reduced to 5 μm or more and 30 μm or less, so that it is possible to reduce the uncomfortable feeling on the skin at the time of application.

  Here, facial skin diseases such as bruises and spots are treated with a laser using a Q-switched YAG laser, etc., and the skin is temporarily in a wound state, or the skin's epidermis is peeled off and is easily tanned Even so, if the tape body 2 of the present embodiment is affixed to a treatment site on the skin of the face subjected to laser treatment, it can be used as a sunscreen for cosmetics. Further, when the tape body 2 is affixed to the face, even when the skin of the face is sensitive due to the thinness of the tape body 2, the uncomfortable feeling at the time of application can be reduced.

  Hereinafter, while showing the prescription example of the coloring agent in the tape main body 2 of an adhesive tape, a comparative test is tried about how much ultraviolet rays are cut, and the test result is shown.

[Prescription Example 1 (UV-1)]
In Formulation Example 1 (UV-1), as shown in Table 1, in the colorant, 77.52% by weight of titanium oxide, 9.70% by weight of iron oxide, and aluminum hydroxide (Al hydroxide) as a pigment coating material 4.49% by weight, 1.10% by weight dimethicone, 1.02% by weight hydrogen dimethicone, 0.87% by weight silica, and 5.30% by weight isotridecyl isononanoate.

[Prescription Example 2 (UV-2)]
In Formulation Example 2 (UV-2), as shown in Table 1, in the colorant, titanium oxide is 62.27% by weight, iron oxide is 24.06% by weight, and aluminum hydroxide (Al hydroxide) is used as a pigment coating material. 4.06% by weight, 1.71% by weight dimethicone, 1.02% by weight hydrogen dimethicone, 0.87% by weight silica, and 6.01% by weight talc as the others.

[Comparison test 1]
In Comparative Test 1, a test specimen a of a tape body in which 20% by weight of the colorant of Formulation Example 1 (UV-1) is blended in polyurethane and the thickness is 10 μm, and the color of Formulation Example 1 (UV-1) is coated on polyurethane. A test sample b of a tape body containing 30% by weight of an agent and having a thickness of 10 μm, a transparent film having a thickness of 10 μm, and a skin-colored nonwoven fabric (3M micropore skin tone (registered trademark)). The transmittance was tested. As a result, as shown in FIG. 4, at 320 nm, the transmittance of the transparent film was 81.7%, the transmittance of the skin-colored non-woven fabric was 31.1%, and the transmittance of the specimen a of the tape body was 6.5%. Thus, the transmittance of the test piece b of the tape main body was 1.6%. From this, it became clear that the test body b containing a large amount of colorant in polyurethane cuts a large amount of ultraviolet rays.
[Comparison test 2]
In the comparative test 2, the test sample c of the tape body in which 30% by weight of the colorant of the formulation example 2 (UV-2) is blended with polyurethane and the thickness is 30 μm, and the color of the formulation example 2 (UV-2) is polyurethane. The transmittance of ultraviolet rays was tested using a tape body specimen d containing 30% by weight of the agent and having a thickness of 10 μm and a skin-colored nonwoven fabric (3M micropore skin tone (registered trademark)). As a result, as shown in FIGS. 5 and 6, at 320 nm, the transmissivity of the skin-colored non-woven fabric is 31.1%, the transmissivity of the test body c of the tape body is 0.1%, and the test body d of the tape main body d The transmittance was 3.2%. From this, it became clear that the test body c with the increased thickness of the tape main body cuts much ultraviolet rays.

  Thus, according to the embodiment, the skin colorant is disposed on the polyurethane base material in an amount of 10 wt% to 40 wt%, and the total amount of titanium oxide and iron oxide is 80 wt% or more. 100% by weight or less, titanium oxide is contained at 53% by weight or more and 91% by weight or less so that the weight ratio of titanium oxide to iron oxide is 10: 1 to 2: 1. Since it is contained in an amount of from 33% by weight to 33% by weight, it is possible to reduce the damage to the skin by cutting off the ultraviolet rays. Moreover, since the polyurethane tape main body 2 is used, the uncomfortable feeling on the skin when the tape main body 2 is affixed can be reduced.

  Here, when the skin colorant is blended in the polyurethane base material in a proportion of less than 10% by weight, the effect of cutting ultraviolet rays is not appropriate, and the skin colorant is added to the polyurethane base material from 40% by weight. When arranged in proportion, it is difficult to stably manufacture the tape body 2. Further, when the total amount of titanium oxide and iron oxide is less than 80% by weight, the effect of cutting off ultraviolet rays is not appropriate.

  Further, in the embodiment, when the tape body 2 is affixed to the treatment site on the skin of the face subjected to the laser treatment and used as a sun protection material, the effect of cutting ultraviolet rays and the skin at the time of application are applied. By reducing the sense of incongruity, it is possible to suitably protect the treatment site on the facial skin subjected to laser treatment.

  Further, in the embodiment, when the carrier 5 that covers the surface of the tape main body 2 is provided so as to support the shape of the tape main body 2, the tape main body 2 can be applied in a desired shape. It can cut and damage to skin can be reduced suitably, and the feeling of strangeness to the skin when tape body 2 is stuck can be reduced. Moreover, when the tape main body 2 is formed in a sheet shape having a thickness of 5 μm or more and 30 μm or less, it is possible to reduce the uncomfortable feeling on the skin when the tape main body 2 is applied. Further, when the tape body 2 is formed in a sheet shape having a thickness of 7 μm or more and 15 μm or less, the discomfort to the skin when the tape body 2 is affixed is greatly reduced, which makes it extremely easy to affix to the face. it can. Here, when the thickness of the tape body 2 is made thinner than 5 μm, the strength of the tape body 2 is lowered and cannot be used stably. When the thickness of the tape body 2 is made thicker than 30 μm, The discomfort to the skin when the main body 2 is affixed increases rapidly.

  In the embodiment, if the pad 3 is provided on the back surface of the tape body 2, the ultraviolet light can be cut to reduce damage to the skin, and the tape body can be used for other purposes. 2 versatility can be improved.

  Note that the adhesive tape of the present invention is not limited to the above-described illustrated examples, and the location where the tape body is applied is not limited to the face, and may be applied to other parts, the tape Of course, the main body may be used for purposes other than sunscreen, and various changes may be made without departing from the scope of the present invention.
