Embodiment

[embodiment 1]

As shown in Figure 1, the skin masking material 2a of embodiment 1 is the layer for possessing film layer 4a and adhesive phase 6a Stack 14.Adhesive phase 6a is laminated in film layer 4a one side 12.

Film layer 4a has retractility.When skin masking material 2a is pasted on into skin, film layer 4a at least a portion Follow the curved surface of skin and the state stretched is presented.Skin masking material 2a can be with the offside of adhesive phase 6a one side 12 The integral sealing of skin contact 16 attached in the mode of curved skin.

In order that film layer 4a has retractility, the film that tensile modulus of elasticity is 0.2~5MPa is preferably used as film Layer 4a raw material.When tensile modulus of elasticity is less than 0.2MPa, film layer 4a can be retractable to more than necessary degree, accordingly, it is difficult to Skin masking material 2a is won with finger tip and is peeled off from skin.When tensile modulus of elasticity is more than 5MPa, film layer 4a will not be chased after With in the curved surface of skin, therefore, skin masking material 2a is possible in a short time from skin peeling after being pasted on skin.Separately When outside, more than 5MPa, after pasting skin masking material 2a, user can feel that skin is tight, and therefore, user, which can produce, does not relax Clothes sense.

The tensile modulus of elasticity value of film determines by the following method.

(1) measure is carried out in nitrogen atmosphere with 35 DEG C.Apply the initial load-carrying 1mN of 10 minutes, sample to sample film Temperature keeps balancing with atmosphere temperature.

(2) sample is made to carry out elongation until load-carrying reaches 30kPa with the draw speed of 100mm/ minutes.

(3) in the state of load-carrying is 30kPa, make sample that creep occur.

(4) specimen length (distance between chuck) when applying the initial load-carrying 1mN of 10 minutes is denoted as L0, load-carrying is reached Specimen length during 30kPa is denoted as L30.Also, obtain E values using following mathematical expression.

E=W × L0/ (L30-L0)

Herein, W value is 30kPa.The E values calculated according to above-mentioned mathematical expression are denoted as to the value of tensile modulus of elasticity.

As film layer 4a raw material, urethane resin system film, vinylacetate system film, acrylic compounds can be included Resin system film, organic siliconresin system film.As acrylic resin system film, it can include what is formed by following copolymer Film, the copolymer using the carbon number of alkyl as 1~8 alkyl acrylate and alkyl methacrylate as mainly into Point, and polymerizable monomer or prepolymer comprising that can be copolymerized with them and with hydrogen bonding capability, comprising 0~20 mole of % Polymerized unit.For example, as acrylic resin system film, the dihydroxypropyls such as hydroxyethyl acrylate (HEA) can be included 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, ethyl acrylate can be exemplified.The mol ratio of methyl methacrylate and ethyl acrylate is, for example, 40:90~40: 180.They are copolymerized to the acrylic resin system film formed in the case where its smooth surface and its thickness are 30 μm, moisture-inhibiting Degree reaches 900~1,300g/ (m²My god).

Or butyl acrylate can be exemplified as alkyl acrylate herein.Methyl methacrylate and acrylic acid fourth The mol ratio of ester is, for example, 10:16~10:25.By they be copolymerized the acrylic resin system film that forms in its smooth surface and In the case that its thickness is 30 μm, moisture permeability reaches 900g/ (m²My god) left and right.

As adhesive phase 6a raw material, can include selected from by acrylic adhesive, elastomeric adhesive, organic Adhesive in the group of silicon systems adhesive, urethane system adhesive and their mixture composition.In addition, acrylic adhesive, Silicon-type adhesive, the moisture permeability of urethane system adhesive are higher than elastomeric adhesive, it is therefore preferable that will be selected from by acrylic acid series Adhesive in the group that adhesive, silicon-type adhesive, urethane system adhesive and their mixture form is used as adhesive Layer 6a raw material obtain the high skin masking material 2a of moisture permeability.

Adhesive phase 6a raw material are more preferably acrylic adhesive., can during using acrylic adhesive Adhesive phase 6a moisture permeability is adjusted by the combination of monomer.For example, it will be selected from by hydroxyethyl acrylamide (HEAA), third The copolymer of 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, adhesive phase 6a moisture permeability uprises.In addition, during using acrylic adhesive, can be by adhesive phase 6a Gel is made.When adhesive phase 6a is gel, when skin masking material 2a is attached at into skin, when being peeled off from skin, The damage of cutin can be suppressed.Acrylic adhesive is HMW body and has cohesive, therefore is glued using acrylic acid series During mixture, adhesive phase 6a is substantially free of the low molecule amount addition of the molecular weight 1, less than 000 of material the reason for can turning into allergy Thing.

Adhesive phase 6a thickness is preferably 10~30 μm.When thickness is less than 10 μm, according to the original as adhesive phase 6a The difference of the adhesive species of material, skin masking material 2a do not have defined bonding force to skin.When thickness is more than 30 μm, After pasting skin masking material 2a, not only cosmetics are possible to be attached to adhesive phase 6a marginal portion and cause border to become It is obvious, it is also possible to as skin masking material 2a tangle finger, clothes and the reason for peel off.In addition, during more than 30 μm, according into For the difference of the adhesive species of raw material, it is difficult to adhesive phase 6a is possessed sufficient penetrability.

Adhesive phase 6a bonding force is the stripping adhesive strength experiment side according to the bonding agent based on JIS K 6854-2 The value that the 180 degree of method is peeled off and determined, bonding force of the skin masking material 2 on SUS plates is preferably 0.1~10 (N/25mm). When bonding force is less than 0.1N/25mm, bonding force is too weak, and therefore, skin masking material 2a is possible in a short time from skin Peel off.When bonding force is more than 10N/25mm, bonding force is too strong, and therefore, when skin masking material 2a is peeled off from skin, having can Skin can be stimulated and damage cutin.

On the film layer 4a another side 10a point height Rz of nao-and micro relief ten, the another of film layer 4a will be coated on When the average grain diameter of the powder included in the cosmetics of face 10a foundation cream, concealer etc is denoted as d, the Rz is 1~60 times of d, That is d≤Rz≤60d.In addition, when film layer 4a thickness is denoted as into w, the Rz of another side 10 is below w, i.e. Rz≤w.Need Bright, another side 10a Rz is according to JIS B 0601:2001 500 μm of datum length, 200 μm of sample length condition Value obtained from the lower surface configuration using surface roughness measurement machine measure another side 10a.

The average grain diameter d of the powder included in cosmetics is according to JIS Z 8825-1:2001 are swashed using granularmetric analysis The accumulated value using volume reference particle size distribution meter of optical diffraction method measure is 50% particle diameter, i.e. median particle diameter.

0.1 μm≤d≤60 μm or so be present in the average grain diameter d of the particle included in the cosmetics of foundation cream, concealer etc Amplitude.On the other hand, another side 10a Rz is 1 times~60 times of d.Another side 10a Rz greatly to more than average grain diameter d, because This, the powder included in cosmetics enters mostly to be formed in the recess in another side 10a bumps, and is maintained in recess. It is considered that：When another side 10a is coated with cosmetics, powder is got into recess, because film layer 4a has retractility, therefore Recesses fit powder shape and stretched, even if 1 times or size close to 1 times of the another side 10a Rz for d, the big portion of powder Dividing can also enter and be maintained in recess.And then another side 10a Rz is average grain diameter d less than 60 times of size, therefore, User can be wiped away into the powder in recess.User can adjust the cosmetics amount for being applied to another side 10a, therefore, It can be finely adjusted while avoiding dressing thicker so that another side 10a tone is consistent with the colour of skin.

Film layer 4a another side 10a thickness w of the concavo-convex difference of height not over film layer 4a is formed at, therefore, Another side 10a Rz is below w.In the state of Rz=w, in other words, it is through in the recess for being formed at another side 10a In the state of adhesive phase 6a is exposed in film layer 4a through hole, the bottom of the through hole, it will can also be included in cosmetics 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 When in order to hide the position be attached at skin, further smear cosmetics on the skin masking material 2a attached surface When, makeup is good.

The currently manufactured urethane film that embossing processing is applied with surface, but its surface texture is：Arithmetic mean roughness Spend Ra and be less than 0.3 μm, Rz is about less than 1 μm.2~60 μ are in even in the surface coating average grain diameter d of conventional urethane film The powder of m scopes, powder can also slide from film surface.

On the other hand, skin masking material 2a another side 10a Rz is d≤Rz≤60d, therefore, even in cosmetics In in the case that the average grain diameter d of powder that includes is in 2~60 μ ms, makeup is also good.It should be noted that on Another side 10a Rz, in the case where d is 2 μm, 2 μm≤Rz≤120 μm and Rz≤w.In the case where d is 6 μm, 6 μm≤ Rz≤360 μm and Rz≤w.In the case where d is 60 μm, 60 μm≤Rz≤3,600 μm and Rz≤w.

[relation of Rz and total light transmittance to another side are studied]

In embodiment 1~10 and comparative example 1, the raw material of the film layer of skin masking material are to make composition identical particulate Disperse the urethane film formed in a manner of it accounts for 13.3 weight % relative to the film weight as film layer raw material, thin The thickness w of film layer be 30 μm this under the same conditions, the size difference of the Rz based on another side, the total light transmittance of sample Produce difference.As shown in table 2 like that, in embodiment 1~10, the Rz of another side is 6~25 μm, the total light transmittance of film layer For 86.0%~89.8%.On the other hand, in comparative example 1, Rz is 0.9 μm, total light transmittance 91.1%.Need what is illustrated It is in comparative example 3, particulate in a manner of occupying 13.3 weight % disperse and the Rz of another side is thin for 5 μm of polyethylene Raw material of the film as film layer, total light transmittance 90.6%.

Shown by the Rz of another side and the relation of total light transmittance of film layer：When Rz is more than 6 μm, total light transmission Rate reaches less than 90%.It is considered that：When Rz, which is more than 6 μm, makes the concavo-convex difference of height for being formed at another side big, inject The light of film layer significantly reflects because concavo-convex, and total light transmittance is reduced to less than 90%.Otherwise it is considered that：Because Rz value is small Make the concavo-convex difference of height hour for being formed at another side in 6 μm, another side is approximate smooth shape, and therefore, incident light is not Easily significantly reflected because concavo-convex.It is considered that：, will in order to which the total light transmittance of skin masking material is remained into less than 90% The Rz of another side is set to 6 μm above is effective.

[studying the relation of particulate and total light transmittance]

In comparative example 1, disperse in a manner of the weight relative to the film as film layer raw material accounts for 13.3 weight % There is particulate, the Rz of another side is 0.9 μm, total light transmittance 91.1%.On the other hand, in comparative example 2, be free of in film layer Particulate, Rz are 3 μm, total light transmittance 95.9%.It is considered that：The total light transmittance although Rz values are larger of comparative example 2 Still the reason for uprising is, particulate is free of in comparative example 2, therefore incident light will not be absorbed because of particulate so as to scatter. It is considered that：In order to which the total light transmittance of the film layer in skin masking material is remained into less than 90%, into film layer Disperse particles is effective.

[studying the relation of particulate and parallel rays transmissivity and mist degree (haze value)]

Similarly, during by comparative example 1 and comparative example 2 contrasting parallel rays transmissivity and mist degree (haze value), although than Big compared with the Rz values of example 2, compared with comparative example 1, the parallel rays transmissivity of film layer still uprises, the mist degree (haze value) of film layer Step-down.It is considered that：Because the film layer of comparative example 2 is free of particulate, thus incident light will not be produced because of particulate and diffusing reflection from And the effect spread.On the other hand, in a manner of the weight relative to the film as film layer raw material accounts for 13.3 weight % Disperse fine-grained embodiment 1~10, in comparative example 1 and 3, regardless of Rz values, parallel rays transmissivity reaches 9.3~ 10.6%, mist degree (haze value) reaches 87.8~89.4%.It is considered that：In order to by the parallel of the film layer in skin masking material Light transmittance remains 0~12%, the mist degree (haze value) of film layer is remained into 84~100%, disperses in film layer micro- Grain is effective.

[embodiment, comparative example adhesive phase in the composition that includes]

It will include in the adhesive phase of the sample for the skin masking material that obtained in embodiment, comparative example for skin Effective component is shown in table 3.In addition, by included in adhesive phase at normal temperatures for liquid and with polar group organic compound Thing and its it is shown in table 4 relative to the weight ratio of adhesive phase.

[table 3]

[table 4]

[to studying at normal temperatures for liquid and with the organic compound of polar group in adhesive phase]

[being used for the composition for preparing the curtain coating solution of adhesive phase in embodiment, comparative example]

For the curtain coating solution as adhesive phase raw material, the part composition of monomer, crosslinking agent is shown in table 5.

[table 5]

[curtain coating used during to preparing adhesive phase is studied with the composition of solution]

The present inventor have studied the list added to curtain coating solution to prepare the adhesive phase of embodiment and comparative example The composition of body, crosslinking agent.When being studied, for the comonomer as crosslinking points as cohesive high-molecular compound, Addition acrylic acid (AA) simultaneously makes its copolymerization, further adds the situation of isocyanates system crosslinking agent, evaluates the bonding of adhesive phase The adhesion characteristics such as power, sticky and cohesive force.Outcome research based on evaluation makes the adhesion characteristic of adhesive phase reach good friendship When joining the addition of agent, in order that the bonding force of adhesive phase is in the range of 0.1~10 (N/25mm) and made sticky, interior Poly- power etc. becomes good, it is necessary to reach 2.0 weight % relative to the weight ratio shared by adhesive phase with the solid constituent of crosslinking agent Mode above largely adds crosslinking agent.

Therefore, as shown in table 5 like that, in the sample prepared as embodiment 1~4,6,7,10 and comparative example 1~3, add Add acrylic acid (AA) as comonomer and make its copolymerization, further with the solid constituent of isocyanates system crosslinking agent relative to viscous Weight shared by mixture layer prepares adhesive phase than reaching compositions more than 2.0 weight %.Nevertheless, embodiment 1~4,6, 7th, 10 and comparative example 1~3 sample still confirm adhesive phase cohesive force is weak, peel sample when easily produce inclining for cull To.It is considered that：Addition acrylic acid (AA) is as comonomer and when making its copolymerization, the reason for cohesive force of adhesive phase dies down It is, because curtain coating is with the single oleic acid sorbitan ester included in solution with high concentration, the friendship of crosslinking agent and acrylic acid (AA) Connection reaction is suppressed, and the crosslinking of cohesive high-molecular compound becomes insufficient.

On the other hand, hydroxyethyl acrylamide (HEAA) is added as the comonomer as crosslinking points and makes it common When poly-, addition Hydroxyethyl Acrylate (HEA) and when making its copolymerization, even if the solid constituent of isocyanates system crosslinking agent relative to Weight shared by adhesive phase is still better than as little as 0.8 weight %, the adhesion characteristic of adhesive phase.

Result based on research, when adding hydroxyethyl acrylamide (HEAA) and making its copolymerization, add dihydroxypropyl Ethyl ester (HEA) and when making its copolymerization, with the weight shared by the solid constituent of isocyanates system crosslinking agent than reaching 0.8 weight %'s Composition prepares embodiment 5,9.It is considered that：Add hydroxyethyl acrylamide (HEAA) or Hydroxyethyl Acrylate (HEA) simultaneously When making its copolymerization, compared with addition acrylic acid (AA) and making the situation that it is copolymerized, cross-linking reaction is not easily susceptible to single oleic acid sorbose The suppression of alcohol acid anhydride ester, even if the addition of isocyanates system crosslinking agent is few, the cross-linking reaction of cohesive high-molecular compound also can Fully carry out.

On the other hand, simultaneously make it common as the comonomer as crosslinking points, addition hydroxyethyl acrylamide (HEAA) It is poly-, and then add as crosslinking agent when the isocyanates system crosslinking agent of (end-blockingization) is protected with end-capping reagent, in order that The adhesion characteristic of adhesive phase becomes good, it is necessary to relative to be blocked the solid constituent of the isocyanates system crosslinking agent of agent protection It is added in the weight shared by adhesive phase than reaching 1.1 weight % mode.

Result based on research, addition hydroxyethyl acrylamide (HEAA) simultaneously make its copolymerization and then addition end-capping reagent During the isocyanates system crosslinking agent of protection, system is formed than reach 1.1 weight % with the weight shared by the solid constituent of crosslinking agent Standby embodiment 8.It is considered that：During the isocyanates system crosslinking agent that addition is protected with end-capping reagent, the feelings with the protection of unused end-capping reagent Condition is compared, it is necessary to largely add crosslinking agent, but can not say that cross-linking reaction is suppressed.It is considered that：Isocyanates system crosslinking agent Molecule in participate in cross-linking reaction be NCO, but the molecular linkage of crosslinking agent has the molecule of end-capping reagent, therefore, isocyanide Perester radical ratio shared in the molecule of crosslinking agent is reduced, and a large amount of addition crosslinkings are needed including the wt part of end-capping reagent Agent.It is considered that：During the isocyanates system crosslinking agent that addition is protected with end-capping reagent, each NCO and the feelings of embodiment 9 Condition similarly carries out cross-linking reaction.

These evaluation results can be said differently by Rz relative to the value of average grain diameter d ratio.In other words, Rz phases When ratio for the average grain diameter d of the powder included in cosmetics is 3.0 times or 4.2 times, compared with the skin do not made up, sense Feel that makeup is constant.When the ratio is 1.7 times, compared with the skin do not made up, feel that makeup has incongruity.The ratio is At 1.0 times, compared with the skin do not made up, feel that makeup is slightly poor.When the ratio is 0.2 times~0.8 times, with the skin do not made up Skin is compared, and feels that makeup is substantially poor.It can be seen from these evaluation results, skin masking material of the invention in order to give play on The good effect of adornment, the Rz of another side are 1.0 times of the average grain diameter d of the powder included in cosmetics above is necessary.

Additionally, it is believed that in comparative example 3, polyethylene (PE) resin and the compatibility of the powder included in cosmetics of film layer Recess band that is low, being formed at another side is cambered, powder easily slide and comparative example 3 in subject perception makeup it is substantially poor The reason for.Think as polyether-polyurethane (EU) resin, polyester polyurethane resin, to include in the resin and cosmetics of film layer Powder compatibility it is high when, can further give play to the good effect of makeup.

It should be noted that in embodiment 1~10, comparative example 1,2, the resin of film layer is set for polyether-polyurethane (EU) Fat, turn into the tensile modulus of elasticity of film of film layer raw material in the range of 0.2~5MPa, after pasting sample, subject Cheek sense of touch there is no incongruity.On the other hand, in comparative example 3, the resin of film layer is polyethylene (PE) resin, turns into thin For the tensile modulus of elasticity of the film of film layer raw material more than 5MPa, after pasting sample, subject feels that cheek is tight, has and does not assist Adjust sense.Therefore, in comparative example 3, subject's trace that dressing is peeled off when unconsciously touching sample with finger after being coated with cosmetics Mark is obvious.Accordingly it will also realize that：On the basis of another side keeps powder, turn into the drawing of the film of film layer raw material Modulus of elasticity is stretched preferably in the range of 0.2~5MPa.
