Detailed description of the invention
[embodiment 1]
As shown in Figure 1, the skin masking material 2a of embodiment 1 is to possess thin layer 4a and the layer of adhesive phase 6a Stack 14.Adhesive phase 6a is laminated in the one side 12 of thin layer 4a.
Thin layer 4a has retractility.When skin masking material 2a is pasted on skin, thin layer 4a's is at least some of Follow the curved surface of skin and present the state that stretched.Skin masking material 2a can be with the offside of the one side 12 of adhesive phase 6a Skin contact 16 integral sealing attach in the mode of curved skin.
In order to make thin layer 4a have retractility, preferably the thin film that tensile modulus of elasticity is 0.2～5MPa is used as thin film The raw material of layer 4a.When tensile modulus of elasticity is less than 0.2MPa, thin layer 4a can be retractable to more than necessary degree, accordingly, it is difficult to Win skin masking material 2a with finger tip and peel off from skin.When tensile modulus of elasticity is more than 5MPa, thin layer 4a will not chase after With in the curved surface of skin, therefore, the most at short notice from skin peeling after skin masking material 2a is pasted on skin.Separately Outward, during more than 5MPa, after pasting skin masking material 2a, user can feel that skin is tight, and therefore, user can produce and not relax Clothes sense.
The tensile modulus of elasticity value of thin film measures by the following method.
(1) mensuration is carried out with 35 DEG C in nitrogen atmosphere.Sample film is applied the initial load-carrying 1mN of 10 minutes, sample Temperature keeps balancing with atmosphere temperature.
(2) sample is made to carry out extending until load-carrying reaches 30kPa with the draw speed of 100mm/ minute.
(3) when load-carrying is 30kPa, sample generation creep is made.
(4) specimen length (chuck spacing) during the applying initial load-carrying 1mN of 10 minutes is denoted as L0, load-carrying is reached Specimen length during 30kPa is denoted as L30.Further, following mathematical expression is used to obtain E value.
E=W × L0/ (L30-L0)
Herein, the value of W is 30kPa.The E value calculated according to above-mentioned mathematical expression is denoted as the value of tensile modulus of elasticity.
As the raw material of thin layer 4a, urethane resin system thin film, vinylacetate system thin film, acrylic compounds can be listed Resin system thin film, organic siliconresin system thin film.As acrylic resin system thin film, can list and be formed by following copolymer Thin film, described copolymer using the alkyl acrylate that carbon number is 1～8 of alkyl with alkyl methacrylate as mainly becoming Point, and comprise and can comprise 0～20 mole of %'s with they copolymerization and the polymerizable monomer with hydrogen bonding capability or prepolymer Polymerized unit.Such as, as acrylic resin system thin film, the dihydroxypropyl such as hydroxyethyl acrylate (HEA) can be listed Arrcostab, hydroxyethyl acrylamide (HEAA) etc. have the acrylamide of hydroxyl.
Herein, as alkyl methacrylate, methyl methacrylate can be exemplified.And then, herein as acrylic acid Arrcostab, can exemplify ethyl acrylate.Methyl methacrylate and the mol ratio for example, 40:90～40 of ethyl acrylate: 180.By the acrylic resin system thin film of they copolymerization in the case of its surface is smooth and its thickness is 30 μm, moisture-inhibiting Degree reaches 900～1,300g/ (m2My god).
Or, herein as alkyl acrylate, butyl acrylate can be exemplified.Methyl methacrylate and acrylic acid fourth The mol ratio of ester for example, 10:16～10:25.By smooth on its surface for the acrylic resin system thin film of they copolymerization and In the case of its thickness is 30 μm, moisture permeability reaches 900g/ (m2My god) left and right.
As the raw material of adhesive phase 6a, the free acrylic adhesive of choosing, elastomeric adhesive, organic can be listed Binding agent in the group of silicon system binding agent, urethane system binding agent and their mixture composition.It addition, acrylic adhesive, Silicon-type binding agent, urethane system binding agent moisture permeability higher than elastomeric adhesive, it is therefore preferable that will select free acrylic acid series Binding agent in the group of binding agent, silicon-type binding agent, urethane system binding agent and their mixture composition is used as binding agent The raw material of layer 6a obtains the skin masking material 2a that moisture permeability is high.
The raw material of adhesive phase 6a more preferably acrylic adhesive.When using acrylic adhesive, can The moisture permeability of adhesive phase 6a is adjusted by the combination of monomer.Such as, will select free hydroxyethyl acrylamide (HEAA), third The copolymer of the monomer in the group of olefin(e) acid alkoxy alkyl, vinylacetate (VA) and their mixture composition is used as bonding During the raw material of agent, the moisture permeability of adhesive phase 6a uprises.During it addition, use acrylic adhesive, it is possible to by adhesive phase 6a Make gel.When adhesive phase 6a is gel, when peeling off when skin masking material 2a is attached at skin, from skin, The damage of cutin can be suppressed.Acrylic adhesive is high molecular body and has cohesive, therefore uses acrylic acid series to glue During mixture, adhesive phase 6a is substantially free of the low-molecular-weight of the molecular weight 1, less than 000 of the reason material that can become allergy to be added Thing.
The thickness of adhesive phase 6a is preferably 10～30 μm.When thickness is less than 10 μm, according to becoming the former of adhesive phase 6a The difference of the binding agent kind of material, skin masking material 2a does not have the bonding force of regulation to skin.When thickness is more than 30 μm, After pasting skin masking material 2a, not only cosmetics are likely attached to the marginal portion of adhesive phase 6a and cause border to become Obvious, it is also possible to become skin masking material 2a and tangle finger, clothes and the reason peeled off.It addition, during more than 30 μm, according to one-tenth Difference for raw-material binding agent kind, it is difficult to make adhesive phase 6a possess sufficient poisture-penetrability.
The bonding force of adhesive phase 6a is the stripping adhesive strength test side according to bonding agent based on JIS K 6854-2 The value that 180 degree of method are peeled off and measured, the skin masking material 2 bonding force on SUS plate is preferably 0.1～10 (N/25mm). When bonding force is less than 0.1N/25mm, bonding force is the most weak, and therefore, skin masking material 2a is the most at short notice from skin Peel off.When bonding force is more than 10N/25mm, bonding force is too strong, and therefore, when being peeled off from skin by skin masking material 2a, having can Skin can be stimulated to make cutin damage.
About nao-and micro relief 10 the height Rz of the another side 10a of thin layer 4a, another of thin layer 4a will be coated When the mean diameter of the powder comprised in the cosmetics of the foundation cream of face 10a, concealer etc is denoted as d, this Rz is 1～60 times of d, I.e. d≤Rz≤60d.During it addition, the thickness of thin layer 4a is denoted as w, the Rz of another side 10 is below w, i.e. Rz≤w.Need Bright, the Rz of another side 10a is in datum length 500 μm, the condition of sample length 200 μm according to JIS B 0601:2001 The value that lower use surface roughness measurement machine measures the surface configuration of another side 10a and obtains.
Mean diameter d of the powder comprised in cosmetics is to utilize granularmetric analysis to swash according to JIS Z 8825-1:2001 The particle diameter that accumulated value in terms of volume reference particle size distribution is 50% of optical diffraction method mensuration, i.e. median particle diameter.
Mean diameter d of the granule comprised in the cosmetics of foundation cream, concealer etc exists about 0.1 μm≤d≤60 μm Amplitude.On the other hand, the Rz of another side 10a is 1 times～60 times of d.The Rz of another side 10a greatly to more than mean diameter d, because of This, the powder comprised in cosmetics mostly enter be formed at another side 10a concavo-convex in recess in, and be maintained in recess. It is believed that: when another side 10a is coated with cosmetics, powder is got in recess, owing to thin layer 4a has retractility, therefore Recesses fit powder shape and is stretched, even if the Rz of another side 10a is d 1 times or close to the size of 1 times, the big portion of powder Divide and also can enter and be maintained in recess.And then, the Rz of another side 10a is the size of less than 60 times of mean diameter d, therefore, User can wipe the powder entered in recess away.User can adjust the cosmetics amount being applied to another side 10a, therefore, Can be finely adjusted so that the tone of another side 10a keeps consistent with the colour of skin while avoiding dressing thicker.
It is formed at the concavo-convex difference of height of another side 10a of the thin layer 4a thickness w not over thin layer 4a, therefore, The Rz of another side 10a is below w.Even if when Rz=w, in other words, being through at the recess being formed at another side 10a Under the state that adhesive phase 6a is exposed in the through hole of thin layer 4a, the bottom of this through hole, it is also possible to by what cosmetics comprised Powder is held in another side 10a.
By above-mentioned composition and effect, skin masking material 2a can be considered the position of abnormal appearance in skin generation Time be attached at skin to hide this position, smear cosmetics further on the surface of the skin masking material 2a attached Time, makeup is good.
The currently manufactured urethane thin film being applied with embossing processing on surface, but its surface texture is: arithmetic mean roughness Degree Ra is less than 0.3 μm, and Rz is about below 1 μm.Even if coating mean diameter d is in 2～60 μ on the surface of conventional urethane thin film The powder of m scope, powder also can be from film surface landing.
