[0001] The present disclosure relates to compositions, film formers, kits, methods for forming a second composition on a first object, and methods for making a film of the composition.

[0002] There are known topical film-forming agents that can be applied to the body surface to form a film that can correct wrinkles, scars, and the like.

[0004] Patent No. 7202422 Patent No. 6105468 Patent No. 7212520

[0005] In view of the above, an object of one embodiment of the present disclosure is to provide a composition that has excellent solubility, can be applied uniformly, and is not sticky after curing.

[0006] In order to solve the above-mentioned problems, one aspect of the composition according to the present disclosure is a composition comprising: (a) at least one of (i) a catalyst for promoting a reaction between a vinyl group and a Si—H group, and (ii) a first compound having a Si—H group; and (b) a solvent, wherein the viscosity of the composition at 25° C. is less than 20 mPa s, the solvent includes a volatile first solvent, and the ratio of the mass of the first solvent to the total mass of the composition is greater than 10 mass %, and / or the ratio of the mass of a non-volatile second solvent to the total mass of the composition is 90 mass % or less.

[0007] According to one aspect of the present disclosure, it is possible to provide a composition that has excellent solubility, can be applied uniformly, and is not sticky after curing.

Fig. 3 is a photograph of the applicator used to evaluate surface smoothness.

[0009] Hereinafter, embodiments of the present disclosure will be described in detail. Note that the embodiments are not limited by the following description and can be modified as appropriate within the scope of the present disclosure. Furthermore, in this specification, unless otherwise specified, the term "to" indicating a range of values ​​means that the values ​​before and after it are included as the lower and upper limits.

[0010] (Composition) <First Embodiment> The composition according to the first embodiment comprises (a) at least one of (i) a catalyst for promoting a reaction between a vinyl group and a Si—H group, and (ii) a first compound having a Si—H group (hereinafter, sometimes referred to as “component (a)”), and (b) a solvent (hereinafter, sometimes referred to as “component (b)”), wherein the viscosity of the composition at 25° C. is less than 20 mPa s, the solvent includes a volatile first solvent, and the ratio of the mass of the first solvent to the total mass of the solvents is greater than 10 mass %, and / or the ratio of the mass of a non-volatile second solvent to the total mass of the solvents is 90 mass % or less. The composition according to the first embodiment may further contain other components in addition to component (a) and component (b), as necessary.

[0011] In the prior art, for example, the compositions described in Patent Documents 1 to 3, when the second agent is applied onto the first agent, the first agent is distorted due to the application pressure, and the surface of the film formed after the second agent is applied is also distorted, resulting in a problem that the surface cannot be made uniform.

[0012] Therefore, the inventors conducted extensive research and came up with the idea of ​​setting the viscosity of the composition at 25°C to less than 20 mPa·s, setting the ratio of the mass of the first solvent to the total mass of the solvent to more than 10 mass%, and / or setting the ratio of the mass of the non-volatile second solvent to the total mass of the solvent to 90 mass% or less. In one aspect, when the viscosity of the composition and the solvent composition meet the above-mentioned conditions, for example, when the above-mentioned composition is used as a second agent in the prior art, the second agent can be uniformly applied on the first agent. It was found that this allows the coating formed after application of the composition according to the first embodiment to be a uniform film, and preferably allows the surface of the coating to be smooth. Furthermore, in another aspect, when the viscosity of the composition and the solvent composition meet the above-mentioned conditions, stickiness of the coating can be suppressed.

[0013] In the present disclosure, the terms "first agent" and "second agent" refer to agents each containing components for forming a film, but the numbers are simply used to separate them for convenience and are not terms that specify the order of application. Therefore, the second agent may be applied on top of the first agent, or the first agent may be applied on top of the second agent. Furthermore, the composition according to the first embodiment may be either the first agent or the second agent.

[0014] According to one embodiment, for example, first, an arbitrary first agent is applied to the skin. Next, a second agent, the viscosity of which and solvent composition meet the above-described conditions, is applied to the skin on which the first agent has been applied. According to this embodiment, since the viscosity of the second agent is relatively low, deformation of the surface shape of the first agent due to application of the second agent can be suppressed. In particular, when the second agent is applied by a spray method (sometimes referred to as the "atomization method") or a stamp method (sometimes referred to as the "sponge method"), the above-mentioned effect is particularly pronounced.

[0015] According to another embodiment, for example, a first agent having a viscosity and solvent composition that meet the above-described conditions is first applied to the skin. Next, an optional second agent is applied to the skin on which the first agent has been applied. According to this embodiment, since the viscosity of the first agent is relatively low and relatively easy to flow, the phenomenon of "twisting" is less likely to occur compared to when a composition that does not meet the above-described conditions is used as the first agent.

[0016] In yet another embodiment, for example, when a user of the composition applies a sticker to their own skin, the user first prepares the sticker. Next, the user applies the first agent to the skin. Next, the user applies the second agent to the back surface of the sticker. The user then places the sticker on the skin to which the first agent has been applied, with the back surface of the sticker facing the skin. This results in the skin, first agent, second agent, and sticker being arranged in this order. The first agent and second agent react with each other, causing the sticker to be attached to the skin. According to this embodiment, the occurrence of the "twisting" phenomenon described above is further suppressed.

[0017] In the above-described application method, the composition used as at least one of the first and second agents may have a viscosity at 25°C of less than 20 mPa·s. Furthermore, the mass ratio of the first solvent to the total mass of the solvents contained in the composition may be greater than 10 mass%, and / or the mass ratio of the non-volatile second solvent to the total mass of the solvents may be 90 mass% or less. This may promote mixing of the first and second agents between the skin and the seal, compared to when a composition that does not meet the above conditions is used as the first or second agent. Furthermore, residual solvent between the skin and the seal may be suppressed.

[0018] In the above-mentioned application method, the application method is not particularly limited, and examples of application methods include spreading using a tool (e.g., a finger, a coater, etc.), spraying, stamping, etc. In the above-mentioned application method, the order of the steps of preparing a sticker, applying the first agent to the skin, and applying the second agent to the back side of the sticker is not particularly limited. In the step of preparing a sticker, a sticker with the second agent applied to its back side may be prepared.

[0019] In yet another embodiment, for example, when a user of the composition applies a sticker to their own skin, the user first prepares the sticker. Next, the user applies any first agent to the skin. Next, the user places the above-mentioned sticker on the skin to which the first agent has been applied. This results in the skin, first agent, and sticker being arranged in this order. The user then applies a second agent, the viscosity of which and solvent composition meet the above-mentioned conditions, over the sticker. The application method is not particularly limited, but it is preferable to use a spray method or a stamp method. According to this embodiment, the viscosity of the second agent is relatively low, so the second agent easily penetrates into the gaps between the skin and the sticker. This makes it possible to realize the above-mentioned application method.

[0020] In the present disclosure, "uniform application" means that when the second agent is applied onto the first agent, the first agent does not crease or the crease is suppressed due to the application pressure, or when the first agent is applied onto the second agent, the second agent does not crease or the crease is suppressed due to the application pressure. Methods that can achieve such application are not particularly limited, and examples include a method of spreading the composition according to the first embodiment with fingers or the like; a method of spraying the composition according to the first embodiment by filling a sprayer or the like with the composition; a method of applying the composition according to the first embodiment to a sponge and applying it to the object to be applied via the sponge using a stamp method; and a method of applying the composition according to the first embodiment to the object to be applied using a writing brush, a silicone spatula, or a paint brush. The composition according to the first embodiment has a viscosity of less than 20 mPa·s at 25°C, and is therefore suitable for these methods, but the application method is not limited thereto.

[0021] In the present disclosure, the terms "subject," "subject to be applied," "subject to be applied," "first object," and "second object" refer to the site to which the composition of the present disclosure is applied.

[0022] In this disclosure, the terms "film," "coating," and "cured film" are all used synonymously.

[0023] [Viscosity] The viscosity of the composition according to the first embodiment at 25° C. is less than 20 mPa·s, preferably 0.5 mPa·s to 19 mPa·s, and more preferably 0.8 mPa·s to 18 mPa·s. If the viscosity of the composition at 25° C. is 20 mPa·s or more, it will not be possible to apply the composition uniformly, and the surface smoothness of the cured film will be poor.

[0024] The viscosity of the composition according to the first embodiment at 25°C is measured at 25°C using a tuning fork vibration viscometer (for example, SV-10, manufactured by A&D Co., Ltd.).

[0025] In the present disclosure, "viscosity" refers to a measure of the resistance of a fluid to being deformed by either shear stress or tensile stress. For example, the viscosity of the composition according to the first embodiment at 25°C affects the thickness, spreadability, and uniformity and / or consistency of the layer formed on the substrate.

[0026] [Dosage Form] The dosage form of the composition according to the first embodiment is not particularly limited, as long as the viscosity of the composition at 25°C can be less than 20 mPa·s.

Furthermore, for example, when the first agent and / or the second agent are separated into water and oil, these agents may be forcibly converted into a two-phase system (oil-in-water or water-in-oil) from the viewpoint of crosslinking reactivity between the first agent and the second agent by shaking. Among these, a single-phase system composed of an anhydrous oil phase is preferred as the dosage form of the composition according to the first embodiment. Each of these dosage forms can be appropriately prepared by a conventional method using component (a), component (b), and optionally other components.

Specifically, the IOB value is expressed as IOB value = inorganic value / organic value. For each of the "inorganic value" and "organic value," "inorganic value" and "organic value" are set according to various atoms or functional groups, for example, an "organic value" of 20 for one carbon atom in a molecule and an "inorganic value" of 100 for one hydroxyl group. The IOB value of an organic compound can be calculated by adding up the "inorganic value" and "organic value" of all atoms and functional groups in the organic compound (see, for example, Yoshio Koda, "Organic Conceptual Diagram - Fundamentals and Applications," pp. 11-17, Sankyo Publishing, 1984).

When the catalyst induces a crosslinking reaction at a temperature equal to or lower than body temperature, the second composition can be formed at room temperature (25°C ± 5°C). When the first object is skin (body surface), the second composition can be formed at body temperature.

[0253] When the ratio of the mass of the first solvent to the total mass of the solvent contained in the first composition is Rs [mass %] and the thickness of the second composition is d [μm], it is preferable to adjust the amounts of the first composition and the second compound so that Rs ≧ 15 is satisfied when d ≦ 54, and Rs ≧ 38.143 − 0.4286 × d is satisfied when d > 54. This makes it possible to prevent oil from seeping out onto the film surface.

[0254] In forming the second composition, the ratio of the number of moles of Si—H groups in the second composition to the number of moles of vinyl groups in the second composition (molar ratio (hydride groups / vinyl groups)) is preferably 0.8 or more and 135 or less from the viewpoint of curability of the second composition, and more preferably 0.8 or more and 70 or less, and even more preferably 8 or more and 35 or less, from the viewpoint of non-stickiness of the film surface of the second composition.

[0255] <<Second Composition>> The second composition is a film-like composition containing a three-dimensionally crosslinked silicone elastomer, and the maximum value of the area of ​​a surface perpendicular to the thickness direction of the second composition is 5 mm ２ More than 50cm ２ The second composition has an average thickness of 300 μm or less, and an average surface roughness Rz of 40 μm or less. The second composition is as described in <Third Embodiment> of (Composition) of the present disclosure.

[0256] [Use] The method for forming the second composition on the first object according to one embodiment can be suitably used as a method for forming a film on skin, an electronic device, or an object. When the first object is skin, the method for forming the second composition on the first object according to one embodiment can be suitably used as a cosmetic method.

[0257] In one embodiment, when the method for forming a second composition on a first object is a cosmetic method, the arranging step preferably comprises arranging the catalyst, the first compound, the second compound, and the second object so that the catalyst, the first compound, and the second compound cover at least a portion of the second object disposed on the surface of the first object, and further comprising forming an uneven shape on the surface of the second composition opposite to the surface that comes into contact with the skin surface.

[0258] The formation of the uneven shape may be performed after the disposing step and before the forming step, or may be performed after the forming step. The uneven shape is not particularly limited and can be appropriately selected depending on the purpose.

[0259] The method for forming the uneven shape is not particularly limited, and examples thereof include a method of pressing a known stamping die or mold onto the first composition after disposing the first composition, or onto the second composition after disposing the second compound on the first composition, or onto the second composition after forming the second compound. This allows the desired uneven shape to be imparted to the second composition (coating) that is finally formed.

[0260] When the uneven shape is a fine, uniform and dense pattern, applying a makeup cosmetic on the second composition improves the application of the makeup.

[0261] When the uneven shape is a fine pattern and is uniform but not dense, it is easy to attach the decoration to the second composition, and the decoration can also be removed without peeling the second composition from the skin.

[0262] The material, shape, structure, size, etc. of the mold are not particularly limited and can be selected appropriately depending on the purpose, but from the viewpoint of conformability to the skin, it is preferable that the mold material be flexible or pliable, and examples thereof include a silicone rubber sheet, a urethane rubber sheet, a silicone mold, and a urethane mold.

[0263] There are no particular limitations on the method for manufacturing the mold. For example, the mold can be designed based on three-dimensional data of the target user's face (support surface), and manufactured using 3D printer data for a custom-made mold.

[0264] Furthermore, when the first object is skin, the method of forming the second composition on the first object according to one embodiment can also be used as a cosmetic method. In the present disclosure, the term "cosmetic method" refers to applying the second composition to skin to form a second composition to beautify the skin condition or a method for beautifying the skin condition, and is different from a method of surgery, treatment, or diagnosis for humans.

[0265] In some embodiments, a known cosmetic may be applied to the skin prior to disposing, or a cosmetic may be applied onto the second composition after forming.

[0266] The cosmetic is not particularly limited and can be appropriately selected from known cosmetic products. For example, skin care cosmetics such as serum, lotion, and emulsion; sunscreen cosmetics (sunscreen cosmetics); base cosmetics; makeup cosmetics such as foundation, gloss, lipstick, eye shadow, and nail polish; or cosmetics that combine the functions of two or more of these cosmetics can be used.

[0267] Furthermore, the method of forming a second composition on a first object according to one embodiment can be suitably used as a method of adhering the first object and the second object when the first object is skin and the second object is a decorative object for imparting design and / or functionality to the first object.

[0268] (Method for Producing a Film-Like Composition) A method for producing a film-like composition according to one embodiment includes: preparing (i) a catalyst for promoting a reaction between a vinyl group and a Si—H group; (ii) a first compound having a Si—H group; and (iii) a second compound that is a compound different from the first compound and has a vinyl group; and reacting the Si—H group of the first compound with the vinyl group of the second compound to form a film-like second composition containing a three-dimensionally crosslinked silicone elastomer, wherein preparing the catalyst, the first compound, and the second compound includes preparing a first composition containing at least one of the catalyst and the first compound, wherein the viscosity of the first composition at 25° C. is less than 20 mPa s, and wherein, in forming the film-like second composition, the maximum value of the area of ​​a plane perpendicular to a thickness direction of the second composition is 5 mm. ２ More than 50cm ２ The average thickness of the second composition is 300 μm or less, and the average surface roughness Rz of the composition is 40 μm or less.

[0269] The preparing and forming can be performed in a manner similar to the method for forming the second composition on the first object in accordance with one embodiment, and the first composition and the second composition are also similar to the method for forming the second composition on the first object in accordance with one embodiment.

[0270] The method for producing a film-like composition according to one embodiment is the same as the method for forming a second composition on a first object according to one embodiment, except that the first object and the second object are not specified, and a film-like composition that is a second composition is produced.

[0271] In the method for producing a film-like composition according to one embodiment, the substrate on which the film-like composition is formed is not particularly limited and can be appropriately selected depending on the purpose. For example, in addition to skin, electronic devices, and optical components, substrates made of any material such as plastic, glass, and silicone, preferably film-like substrates, can also be used.

[0272] The film-like composition produced by the method for producing a film-like composition according to one embodiment can be used by peeling only the film-like composition from the substrate and applying it to a desired site. For example, a film-like composition formed on a substrate such as plastic or silicone can be stored using the substrate as a protective film, and when in use, the substrate can be peeled off and the composition can be applied to a desired site, such as the skin.

[0273] The embodiments will be described in more detail below with reference to Examples, Comparative Examples, and Test Examples, but the embodiments are not limited to these Examples, Comparative Examples, and Test Examples. In the Examples, Comparative Examples, and Test Examples, the blending amounts are expressed in "% by mass" relative to the total mass of the composition unless otherwise specified.

[0274] [Evaluation Method] In the following examples and comparative examples, the "solubility" and "sprayability" of the prepared second part were evaluated by the following methods, the viscosity was measured by the following method, and the hydride group / vinyl group [molar ratio] was calculated by the following method. In addition, in the following examples and comparative examples, the "film curability" and "oil exudation from the film surface" of the second composition formed by applying the second part onto the prepared first part, i.e., the cured film, were evaluated by the following methods. The applicator used was the applicator shown in Figure 3, which was produced using a 3D printer.

[0275] <<Evaluation of Solubility of Second Agent>> The second agents prepared in the Examples and Comparative Examples were placed in transparent vials, and one expert panelist visually inspected the appearance and evaluated the solubility of the second agent based on the following evaluation criteria. Evaluations A and B are within the practical range. -Evaluation criteria- A: Transparent and dissolved B: Cloudy C: The platinum catalyst and the first solvent separated and did not dissolve at all

[0276] <<Evaluation of sprayability of second agent>> The second agents prepared in the examples and comparative examples were placed in a sprayer (spray vial, manufactured by Nippon Electric Glass Co., Ltd.) and sprayed. One expert panelist visually confirmed the state of spray and evaluated the sprayability of the second agent based on the following evaluation criteria. Evaluation A is within the practical range. - Evaluation criteria - A: Able to spray radially B: Cannot spray radially

[0277] <<Evaluation of Film Curability>> A natural rubber sheet (THERABAND, manufactured by Sakai Medical Co., Ltd.) was attached to a methyl methacrylate (PMMA) plate to prepare a substrate having a square surface measuring 5 cm long x 5 cm wide. A square coating area measuring 3 cm long x 3 cm wide was determined in the center of the substrate, and the surrounding area of ​​the substrate other than the coating area was masked with masking tape. Next, 90 mg of the first agent prepared in the Examples and Comparative Examples was applied to the coating area on the substrate using the applicator shown in Figure 3. Next, 90 mg of the second agent prepared in the Examples and Comparative Examples was placed in a sprayer (spray vial, manufactured by Nippon Electric Glass Co., Ltd.) and sprayed from directly above the coated area of ​​the first agent, 15 cm away from the coated area of ​​the first agent. Next, the masking on the substrate was removed, and the surface of the substrate opposite to the surface coated with the first and second components was placed in contact with a hot plate at 32°C for 30 minutes, and dried on the hot plate for 30 minutes under conditions of a relative humidity of 35±5%. One expert panelist rubbed the film of the second composition formed after drying with a spatula at a force of 2N to 3N, and evaluated the curability of the film based on the following evaluation criteria. Note that evaluation A represents a range that is practically usable without any particular limitations on the application, and evaluation B represents a range that is practically usable, for example, for applications where strong external forces are unlikely to be applied or where the use period is short. - Evaluation Criteria - A: The surface of the film is sufficiently cured, and the film cannot be scraped off when rubbed with a spatula. B: The surface of the film is cured, but the film can be scraped off when rubbed with a spatula. N.D.: The second component cannot be sprayed from the sprayer, and a film cannot be formed.

[0278] <<Evaluation of Oil Bleeding from Film Surface>> A natural rubber sheet (THERABAND, manufactured by Sakai Medical Co., Ltd.) was attached to a methyl methacrylate (PMMA) plate to prepare a substrate having a square surface measuring 5 cm long x 5 cm wide. A square coating area measuring 3 cm long x 3 cm wide was determined in the center of the substrate, and the surrounding area of ​​the substrate other than the coating area was masked with masking tape. Next, 90 mg of the first agent prepared in the Examples and Comparative Examples was applied to the coating area on the substrate using the applicator shown in Figure 3. Next, the second agent prepared in the Examples and Comparative Examples was placed in a sprayer (spray vial, manufactured by Nippon Electric Glass Co., Ltd.), and 90 mg was sprayed from directly above the coating area of ​​the first agent, 15 cm away from the coating area of ​​the first agent. Next, the masking on the substrate was removed, and the surface of the substrate opposite to the surface coated with the first and second components was placed in contact with a hot plate at 32°C, and dried on the hot plate for 30 minutes under conditions of a relative humidity of 35±5%. The gloss of the film as the second composition formed after drying was measured using a gloss meter (Gloss Checker, manufactured by Horiba, Ltd.) at a measurement angle of 60°. From the measured gloss value, oil exudation from the film surface was evaluated based on the following evaluation criteria. The gloss value is expressed as an integer. Ratings A and B are within the practical range. In the evaluation of film curability, if the second component could not be sprayed from the sprayer and a film could not be formed, the gloss of the film could not be evaluated either, and was therefore indicated as "N.D." - Evaluation criteria - A: Gloss of 1 to 4 B: Gloss of 5 to 24 C: Gloss of 25 or more

[0279] <<Viscosity Measurement>> The viscosity of the second parts prepared in the examples and comparative examples was measured at 25° C. using a tuning fork vibration viscometer (SV-10, manufactured by A&D Co., Ltd.).

[0280] <<Calculation of Hydride Group / Vinyl Group [Mole Ratio]>> The hydride group / vinyl group [mole ratio] in the second composition formed in the Examples and Comparative Examples is the ratio of the number of moles of hydride groups (Si—H groups) in the first compound having an Si—H group to the number of moles of vinyl groups in the second compound having a vinyl group, and was calculated based on the amount of the first compound having an Si—H group and the second compound having a vinyl group charged in the first agent and / or second agent used when forming the second composition in the Examples and Comparative Examples. Note that when the first agent and / or second agent contains a platinum catalyst (Karstedt's catalyst), vinyl dimethicone and divinyl disiloxane are contained in the platinum catalyst (Karstedt's catalyst), but because the amounts thereof are trace, they were not taken into consideration in calculating the hydride group / vinyl group [mole ratio].

[0289] Examples 6 to 8 Preparation of First Agent A first agent was prepared with the same composition and blending amounts as in Example 5.

[0290] <Preparation of Second Agent> The second agents of Examples 6 to 8 were prepared in the same manner as in Example 5, except that the type of first solvent in Example 5 was changed as shown in Table 2.

[0293] Examples 10 and 11 Preparation of First Agent A first agent was prepared with the same composition and blending amounts as in Example 5.

[0294] <Preparation of Second Agent> Second agents of Examples 10 and 11 were prepared in the same manner as in Example 9, except that the type of second solvent in Example 9 was changed as shown in Table 2. Dimethicone KF-96A-6CS (kinematic viscosity: 6.0 cSt, Shin-Etsu Chemical Co., Ltd.) was used.

[0295] Comparative Examples 4 to 6 Preparation of First Agent A first agent was prepared with the same composition and blending amounts as in Example 5.

[0296] <Preparation of Second Agent> Second agents of Comparative Examples 4 to 6 were prepared in the same manner as in Example 5, except that the first solvent in Example 5 was changed to the second solvent shown in Table 2. Neo Heliopan (registered trademark) OS (JSQI) (manufactured by Symrise AG) was used as the octyl salicylate, and NIKKOL CIO (manufactured by Nikko Chemicals Co., Ltd.) was used as the cetyl 2-ethylhexanoate.

[0297] The evaluation results of the "solubility" and "sprayability" of the second agents prepared in Examples 1 to 11 and Comparative Examples 1 to 6, as well as the "curability of the film" and "oil seepage from the film surface" for the films as the second compositions formed by applying the second agent onto the first agent, are shown in Tables 1 and 2.

[0298]

[0299]

[0300] The results in Tables 1 and 2 show that when only a non-volatile solvent is used as the solvent in the second agent, oil seeps onto the film surface, making the surface sticky. Therefore, it is suggested that the solvent in the second agent should preferably contain a volatile solvent.

[0301] Examples 12 to 21 and Comparative Examples 7 to 8 Preparation of First Agent A first agent was prepared with the same composition and blending amounts as in Example 1.

[0302] <Preparation of second agent> The second agents of Examples 12 to 21 and Comparative Examples 7 and 8 were prepared in the same manner as in Example 1, except that the blending amounts of the platinum catalyst and the first solvent in Example 1 were changed as shown in Table 3.

[0303] The evaluation results for the "solubility" and "sprayability" of the second agents prepared in Examples 12 to 21 and Comparative Examples 7 to 8, as well as the "curability of the film" and "oil seepage from the film surface" for the films as the second compositions formed by applying the second agent onto the first agent, are shown in Table 3.

[0304]

[0305] The results in Table 3 suggest that in the second agent, the ratio of the mass of the first solvent to the total mass of the solvent is more than 10 mass% and / or the ratio of the mass of the non-volatile second solvent to the total mass of the solvent is 90 mass% or less, thereby suppressing the seepage of oil from the film surface.

[0306] (Test Example 1) In the evaluation of oil seepage from the film surface in Examples 12 to 21 and Comparative Examples 7 to 8, (1) when the coating amount of the first agent was 45 mg and the coating amount of the second agent was 45 mg, (2) when the coating amount of the first agent was 90 mg and the coating amount of the second agent was 90 mg, and (3) when the coating amount of the first agent was 180 mg and the coating amount of the second agent was 180 mg, the oil seepage from the film surface of the film as the second composition was evaluated using the same method and the same evaluation criteria. At this time, the lower limit of the ratio of the mass of the first solvent to the total mass of the solvent at which an evaluation result of A or B was obtained was determined. The film thickness at the lower limit of the ratio of the mass of the first solvent to the total mass of the solvent was measured using a high-precision digimatic micrometer (MDH-25MB, manufactured by Mitutoyo Corporation), and the results are shown in Table 4.

[0307]

[0308] From the results in Table 4, a graph showing the relationship between the film thickness of the second composition and the lower limit of the mass ratio of the first solvent to the total mass of the solvent at which an evaluation result of A or B was obtained in the evaluation of oil seepage from the film surface of the film as the second composition is shown in Figure 2. From this graph, the relationship shown in the following formula 3 and formula 4 was obtained. [Formula 3] When d≦54, Rs≧15 [Formula 4] When d>54, Rs≧38.143−0.4286×d In formulas 3 and 4, Rs represents the lower limit [mass %] of the mass ratio of the first solvent to the total mass of the solvent contained in the first agent, and d represents the film thickness [μm] of the second composition.

[0309] Examples 22 to 36 and Comparative Examples 9 to 12 Preparation of First Agent A first agent was prepared with the same composition and blending amounts as in Example 1.

[0310] <Preparation of Second Agent> A second agent was prepared based on the composition and blending amounts shown in Tables 5-1 and 5-2. Specifically, 1,000 cSt of platinum catalyst (Karstedt's catalyst) as a catalyst for promoting the reaction between vinyl groups and Si—H groups and 1.5 cSt of dimethicone (KF-96L-1.5CS) as a first solvent were blended in the blending amounts shown in Tables 5-1 and 5-2 and mixed uniformly to prepare a second agent.

[0311] The evaluation results of the "solubility" and "sprayability" of the films prepared in Examples 22 to 36 and Comparative Examples 9 to 12, as well as the "curability of the film" and "oil bleeding from the film surface" for the films as the second composition formed by applying the second agent onto the first agent, are shown in Tables 5-1 and 5-2.

[0312]

[0313]

[0314] In Comparative Examples 9 to 12, the viscosity of the second part was as high as 20 mPa·s or more, making it impossible to spray radially with a sprayer. As a result, a cured film could not be formed, and the "film curability" and "oil exudation from the film surface" could not be evaluated. Furthermore, it was suggested that in order to achieve a viscosity range suitable for spraying the second part, the ratio of the mass of the catalyst to the total mass of the second part should preferably be more than 0.07 mass% and less than 35 mass%.

[0315] Examples 37 to 53 and Comparative Examples 13 to 14 Preparation of First Agent A first agent was prepared with the same composition and blending amounts as in Example 5.

[0316] <Preparation of Second Agents> Second agents of Examples 37 to 53 and Comparative Examples 13 to 14 were prepared in the same manner as in Example 5, except that the blending amounts of hydrogen dimethicone as the first compound and the first solvent in Example 5 were changed as shown in Tables 6-1 and 6-2.

[0317] The evaluation results of the "solubility" and "sprayability" of the second agents prepared in Examples 37 to 53 and Comparative Examples 13 to 14, as well as the "curability of the film" and "oil seepage from the film surface" for the films as the second compositions formed by applying the second agent onto the first agent, are shown in Tables 6-1 and 6-2.

[0318]

[0319]

[0320] In Comparative Examples 13 and 14, the viscosity of the second part was as high as 20 mPa·s or more, and it was not possible to spray radially with a sprayer. Therefore, a cured film could not be formed, and the "film curability" and "oil exudation from the film surface" could not be evaluated. Furthermore, it was suggested that in order to more effectively suppress oil exudation from the film surface, it is preferable to set the hydride group / vinyl group [molar ratio] in the second part to 0.8 or more and 70 or less.

[0322] <Preparation of Second Agent> A second agent was prepared based on the composition and blending amounts shown in Table 7-1. Specifically, 1,000 cSt of platinum catalyst (Karstedt's catalyst) as a catalyst for promoting the reaction between vinyl groups and Si—H groups and 1.5 cSt of dimethicone (KF-96L-1.5CS) as a first solvent were blended in the blending amounts shown in Table 7-1 and mixed uniformly to prepare the second agent.

[0327] Comparative Example 17 Preparation of First Agent A first agent was prepared with the same composition and blending amounts as in Example 1.

[0338] The evaluation results of the "solubility" and "sprayability" of the second agents prepared in Examples 54 to 60 and Comparative Examples 15 to 20, as well as the "curability of the film" and "oil exudation from the film surface" for the films as the second compositions formed by applying the second agent onto the first agent, are shown in Tables 7-1 and 7-1. Furthermore, in Examples 54 to 60 and Comparative Examples 15 to 20, the "surface smoothness" of the films as the second compositions formed by applying the second agent onto the first agent was also evaluated by the following method. The evaluation results are shown in Tables 7-1 and 7-1.

[0339] <<Evaluation of Surface Smoothness>> A natural rubber sheet (THERABAND, manufactured by Sakai Medical Co., Ltd.) was attached to a methyl methacrylate (PMMA) plate to prepare a substrate having a square surface measuring 5 cm long x 5 cm wide. A square coating area measuring 3 cm long x 3 cm wide was determined in the center of the substrate, and the surrounding area of ​​the substrate other than the coating area was masked with masking tape. Next, 90 mg of each of the first agents prepared in Examples 54 to 60 and Comparative Examples 15 to 20 was applied to the coating area on the substrate using the applicator shown in Figure 3. Next, the second agents prepared in Examples 54 to 60 and Comparative Examples 15 to 20 were placed in a sprayer (spray vial, manufactured by Nippon Electric Glass Co., Ltd.), and 90 mg of each was sprayed from directly above the coated area of ​​the first agent, 15 cm away from the coated area of ​​the first agent. Next, the masking on the substrate was removed, and the surface of the substrate opposite to the surface coated with the first and second components was placed in contact with a hot plate at 32°C. The substrate was then dried on the hot plate for 30 minutes under conditions of 35±5% relative humidity. After drying, the surface roughness Rz of the film as the second composition formed by coating the second component on the first component was measured under the following measurement conditions. The surface roughness Rz of the film was measured using a one-shot 3D shape measuring instrument (VR3100, manufactured by Keyence Corporation) at 12x magnification. Waviness of λ=0.8 mm or more was excluded to eliminate distortion of the substrate itself. As shown in Figure 1, three roughness curves were taken at equal intervals in the horizontal direction on the coated surface of the substrate, and Rz was calculated, and the average value of the three curves was calculated. The average value of these three curves was taken as the "surface smoothness" of the film as the second composition, and is shown in Tables 7-1 and 7-2.

[0340]

[0341]

[0342] The results of Tables 7-1 and 7-2 show that in Comparative Examples 15 to 20, in which the viscosity of the second part at 25°C exceeded 20 mPa s, spraying was not possible, and application was performed using the applicator shown in Figure 3, and the surface hardened while application pressure was applied, resulting in a rough surface of the film of the second composition. In contrast, in Examples 54 to 60, spraying was possible, and the surface of the film could be hardened without application of application pressure, so a film of the second composition with excellent surface smoothness could be formed.
