Embodiment approach 1

[0035] Such as figure 1 As shown, the skin masking material 2a of the first embodiment is a laminate 14 including a film layer 4a and an adhesive layer 6a. The adhesive layer 6a is laminated on one side 12 of the film layer 4a.

[0036] The film layer 4a has stretchability. When the skin masking material 2a is attached to the skin, at least a part of the film layer 4a is stretched following the curved surface of the skin. The skin masking material 2a can be attached so that the entire skin-contacting surface 16 opposite to the one surface 12 of the adhesive layer 6a closely adheres to the curved skin.

[0037] In order to impart stretchability to the film layer 4a, a film having a tensile modulus of 0.2 to 5 MPa is preferably used as a raw material of the film layer 4a. When the tensile modulus is less than 0.2 MPa, the film layer 4a expands and contracts more than necessary, making it difficult to pick and peel the skin masking material 2a from the skin with fingertips. ...

Embodiment approach 2

[0060] In this specification, the same code|symbol shown in each drawing represents the same or the same member. about figure 1 The skin-shielding material 2b according to Embodiment 2 shown will be described with respect to the different configurations and operational effects from the skin-shielding material 2a. The Rz of the other surface 10b of the skin masking material 2b is 6 μm≤Rz≤40 μm, and Rz≤w.

[0061] Compared with the conventional skin masking material, the skin masking material 2b has a larger unevenness formed on the other surface 10b, and the powder contained in cosmetics is easily retained in the concave portion. Furthermore, the Rz of the other surface 10b of the skin masking material 2b is Rz≦40μm, so the level difference of the unevenness will not be too large, and it is extremely easy to wipe off the powder held in the concave portion. The user can easily touch up the makeup, so there is no need to carefully adjust the color.

Embodiment approach

[0121] about Figure 2-5 The skin masking materials ( 2f , 2g , 2h , 2i , 2j ) of other shown embodiments will be described with respect to their different configurations and operational effects from the skin masking materials ( 2a , 2b ).

[0122] figure 2 The material of the film layer 4f in the shown skin masking material 2f is a composite film 38 in which a urethane film 34 having irregularities and a hydrophobic film 36 are laminated. Examples of the material of the hydrophobic film 36 include hydrophobic synthetic resins selected from the group consisting of polyolefin resins, thermoplastic elastomers, rubber-based resins, and mixtures thereof. Here, examples of thermoplastic elastomers include styrene-isoprene-styrene block copolymers, styrene-butadiene copolymers, and their modified products based on acrylics and the like. In addition, examples of the rubber-based resin here include isoprene rubber, butyl rubber, polyisobutylene, and modified products thereof. The ...

Abstract

Provided is a skin masking material that is attached to the skin in order to hide a site that is considered to be abnormal in appearance when the skin has an abnormal appearance, and when cosmetics are applied to the surface of the attached skin masking material, makeup sex is good. A skin masking material in which an adhesive layer is laminated on one side of a stretchable film layer, the average particle diameter of a powder contained in cosmetics coated on the other side of the film layer is denoted as d, and the thickness of the film layer is When written as w, Rz on the other side satisfies d≤Rz≤60d and Rz≤w. Since Rz on the other surface is as large as the average particle diameter d or more, powders of cosmetics often enter the unevenness formed on the other surface and are held in the unevenness.

Description

technical field [0001] The present invention relates to a skin masking material attached to the skin. Background technique [0002] People who have heterogeneous parts such as moles and spots on the skin of the face want to hide the heterogeneous parts from being seen by others. Therefore, cosmetics such as foundation and concealer have been used to cover the uneven parts and put on makeup. However, cosmetics run off when exposed to sweat, and peel off when touched by hands or objects, making it impossible to cover foreign parts with confidence. [0003] In contrast, Patent Document 1 discloses a skin masking material in which an adhesive layer is laminated on one side of a film layer and fine unevenness is formed on the other side of the film layer. When the skin masking material described in Patent Document 1 is pasted on the heterogeneous part, the heterogeneous part is covered and hidden. Furthermore, when cosmetics are applied to the attached skin masking material, t...
