[0280] The composition of the present disclosure may or may not contain a solvent. In the case of containing a solvent, it is usually supplied for curing after removing the solvent as described above.

[0281] 8-1. Curable composition

[0282] The composition of the present disclosure comprises the polysiloxane compound represented by the formula (1), and the radical polymerization initiator and / or cationic polymerization initiator. Further, the other components may be included. When a solvent is included as the other component, generally, before the composition of the present disclosure is cured, the solvent is removed by drying or the like to obtain a cured product, which is used as a primer coat. Therefore, among all the components other than the solvent in the composition of the present disclosure, the proportion of the polysiloxane compound represented by the formula (1) is preferably 50 parts by weight or more, more preferably 70 parts by weight or more, and still more preferably 90 parts by weight or more. By setting it within the preferred range, a cured product with good adhesion to the inorganic material layer can be obtained.

[0283] In the case of a mixed solvent, its usage amount can be arbitrarily set according to the purpose and is not particularly limited. For example, relative to 100 parts by weight of the polysiloxane compound represented by the formula (1), it can be 1 to 20,000 parts by weight, more preferably 10 to 1,000 parts by weight, and still more preferably 50 to 500 parts by weight.

[0284] 8-2. Coating method

[0285] The method for coating the composition of the present disclosure on a resin substrate is not particularly limited and is appropriately selected according to the constituent material and shape of the substrate, etc. For example, common coating methods such as casting method, spin coating method, bar coating method, dip coating method, spraying method, roll coating method, flow coating method, and gravure coating method can be used.

[0286] The coating thickness of the composition of the present disclosure is not particularly limited and can be arbitrarily set according to the purpose. It is preferably 0.1 to 100 μm, more preferably 0.5 to 50 μm, and still more preferably 1 to 10 μm.

[0287] 8-3. Curing method

[0288] In the present disclosure, according to whether the curable composition is curable by active energy rays and / or heat, its curing method and curing conditions are selected. In addition, the curing conditions are appropriately selected according to the type and amount of the polymerization initiator and the types of other polymerizable compounds contained in the composition of the present disclosure (in the case of curing by active energy rays, for example, the type of light source and the light irradiation amount, etc.; in the case of heat curing, the heating temperature and heating time, etc.).

[0289] (1) Actinic energy ray curing method

[0290] When the composition of the present disclosure is a curable composition for active energy rays, as its curing method, irradiation with active energy rays can be performed using a known active energy ray irradiation device or the like. Examples of the active energy rays include electron beams, and light such as ultraviolet rays, visible rays, and X-rays. However, light is preferably used because a cheap device can be used, and ultraviolet rays are more preferably used.

[0291] Examples of the ultraviolet irradiation device include a low-pressure mercury lamp, a medium-pressure mercury lamp, a high-pressure mercury lamp, an ultra-high-pressure mercury lamp, a metal halide lamp, an ultraviolet (UV) electrodeless lamp, a chemical lamp, a black light, a microwave-excited mercury lamp, and a light-emitting diode (LED).

[0292] The light irradiation intensity on the film coated with the composition of the present disclosure can be selected according to the purpose, use, etc. The light irradiation intensity in the light wavelength region effective for activating the active energy ray polymerization initiator (referred to as a photoinitiator in the case of photocuring) (varies depending on the type of the photoinitiator, but light with a wavelength of 220 to 460 nm is preferably used) is preferably 0.1 to 1000 mW / cm 2 .

[0293] In addition, the irradiation energy should be appropriately set according to the type of the active energy ray and the composition, and the light irradiation time on the film can also be selected according to the purpose, use, etc. It is preferable to set the cumulative light amount, which is the product of the light irradiation intensity and the light irradiation time in the light wavelength region, to 10 to 7,000 mJ / cm 2 . More preferably, it is 200 to 5,000 mJ / cm 2 , and further preferably 500 to 3500 mJ / cm 2 . As long as the cumulative light amount is within the above range, the curing of the composition can be smoothly performed, and a uniform cured product can be easily obtained.

[0294] In addition, heat curing can be appropriately combined before and / or after photocuring.

[0295] For example, two-stage curing can be performed. In this case, when the composition of the present disclosure penetrates into a substrate having a portion that becomes a shadow when irradiated with light, and then light is irradiated, first, the composition of the present disclosure at the portion irradiated with light is cured, and then heat is applied to cure the composition of the present disclosure at the portion not irradiated with light. Such a substrate is not particularly limited, and examples thereof include substrates having complex shapes such as cloth-like, fibrous, powdery, porous, and uneven shapes, and may also be a combination of two or more of these shapes.

[0296] (2) Thermal curing method

[0297] When the composition of the present disclosure is a thermosetting composition, its curing method and curing conditions are not particularly limited.

[0298] The curing temperature is preferably 80°C to 200°C, more preferably 100°C to 180°C, and further preferably 110°C to 150°C. Additionally, the curing temperature can be a constant temperature or a temperature increase. Furthermore, a temperature increase and a temperature decrease can also be combined.

[0299] The curing time is appropriately selected according to the type of the thermal polymerization initiator and the content ratio of other components, etc., and is preferably 10 to 360 minutes, more preferably 30 to 300 minutes, and further preferably 60 to 240 minutes. By curing the film under the above preferred conditions, a uniform cured film without swelling, cracks, etc. can be formed.

[0300] 8-4. Physical properties of cured product

[0301] The cured product obtained by curing the composition of the present disclosure (also simply referred to as "the cured product of the present disclosure" in this specification) has excellent adhesion to the resin substrate and to the inorganic material layer. The index of adhesion is not particularly limited, and known indexes are applicable, but for example, evaluation indexes based on a checkerboard peel test (cross-cut method) etc. can be cited. In the case of adopting the checkerboard peel test, for the inorganic material layer of the laminate, its adhesion can be evaluated according to JIS K5600-5-6 (ISO-2409).

[0302] In addition, the cured product of the present disclosure has excellent hardness. The index of hardness is not particularly limited, and known indexes are applicable, but for example, evaluation indexes based on a pencil hardness test and an abrasion resistance test (scratch test) etc. can be cited.

[0303] In addition, the cured product of the present disclosure is excellent in transparency, coloring resistance, ultraviolet resistance, flexibility, resin substrate followability, weather resistance, chemical resistance, abrasion resistance, durability, heat resistance, etc.

[0304] The cured product of the present disclosure is obtained by curing a composition mainly composed of the polysiloxane compound represented by the formula (1). The polysiloxane compound related to the present disclosure contains T units, and preferably also contains D units and / or M units. Therefore, the SiO content rate in the cured product, that is, the content rate of the inorganic components contained in the cured product, is high, and thus the adhesion to the inorganic material layer laminated thereon is excellent. The cured product of the present disclosure containing D units and / or M units is more excellent in flexibility or resin substrate followability, and thus is preferred. In addition, the cured product of the present disclosure containing D units and / or M units is more excellent in surface smoothness, and thus is preferred.

[0305] By appropriately balancing and adjusting the composition ratios of the respective components of the polysiloxane according to the purpose and use, particularly the composition ratios of the structural unit (b) and the structural unit (c), the cured product of the polysiloxane compound according to the present disclosure can exhibit physical properties such as good adhesion to the resin substrate, good adhesion to the inorganic material layer, hardness, flexibility, and resin substrate followability in good balance.

[0306] 9. Laminate

[0307] The laminate of the present disclosure includes the above-mentioned cured product of the present disclosure, a resin substrate, and an inorganic material layer. The laminate of the present disclosure preferably includes: at least one of the resin substrates, a cured product for laminating the inorganic material layer of the present disclosure on which the inorganic material layer of the present disclosure laminated thereon is cured, and further at least one of the inorganic material layers laminated thereon. Its structure is not particularly limited and can be arbitrarily selected according to the purpose, use, etc. For example, when the resin substrate is a film, the cured product of the present disclosure and the inorganic material layer can be laminated in sequence on one surface, and in addition, the cured product of the present disclosure and the inorganic material layer can be laminated in sequence on the two surfaces of the film, respectively.

[0311] In addition, it can be used as a decorative printed film laminate, which is useful as a decorative film for display substrates, touch panels, thin films with transparent strip electrodes, lens sheets, optical waveguides, solar cell substrates, optical discs, various transparent substrates, etc.

[0312] The functions of having an inorganic material layer or a laminate are not particularly limited, and examples include antireflection, antifogging, gas barrier, hard coating, scratch resistance, wear resistance, appearance design, antistatic, conductive, moisture resistance, weather resistance, light resistance, waterproof, oil resistance, stain resistance, antibacterial, antiviral, anti-bioactivity, ultraviolet resistance, cosmic ray resistance, acid plasma resistance, atomic oxygen resistance, etc.

In the 25-square grid, the evaluation was made based on the number of peeled squares. The fewer the number of peeled squares, the higher the adhesion. In Example 34, there were no peeled squares, that is, 0 squares.

[0444] It should be noted that in this evaluation, there were no peeled squares between the resin substrate and the thermoset of the undercoat agent composition.

[0468] (6) Abrasion resistance test of inorganic substance layer: Scratch test

[0469] <Example 42>

[0470] Using polysiloxane compound 1, PC as the resin substrate, and SiO2 as the inorganic substance layer, a scratch test was conducted on the inorganic substance layer of the laminate produced in the manner of Example 3 under the following conditions, and the critical load value was measured to evaluate the abrasion resistance of the inorganic substance layer.

[0471] Device used: Micrometer Scratch Tester (CSR-5000) manufactured by Rhesca Co., Ltd.

[0472] Diameter of the indenter (front end needle): 25 μm

[0473] Scratch speed: 10 μm / sec

[0474] Amplitude width: 100 μm

[0475] Marked load: 10 mN / sec

[0476] As a result, the critical load value was 42.1 mN. The results are shown in Table 4. The larger this value, the higher the abrasion resistance.

[0477] <Examples 43 to 56>

[0478] Except for using polysiloxane compounds 1, 5, 9, or 11, using PC, PMMA, or PET as the resin substrate, and using SiO2 or ZrO2 as the inorganic substance layer, laminates were produced in the same manner as in Example 42, and the abrasion resistance of the respective inorganic substance layers was evaluated.

[0480] Using polysiloxane compound 12, using PC as the resin substrate, after forming a curable composition for inorganic substance lamination on the PC as in Example 29, SiO2 was laminated by ion plating. For the produced laminate, the abrasion resistance of the inorganic substance layer was evaluated in the same manner as in Example 42. As a result, the critical load value was 51.1 mN. The results are shown in Table 4.

[0481] <Example 58>

[0482] Except for using polysiloxane compound 13, a laminate was produced in the same manner as in Example 57, and for this laminate, the abrasion resistance of the inorganic substance layer was evaluated. As a result, the critical load value was 69.3 mN. The results are shown in Table 4.

[0483] <Example 59>

[0484] Using polysiloxane compound 11, with PC as the resin substrate, after forming a cured product for inorganic material lamination on the PC as in Example 34, ZrO2 was laminated by ion plating. For the fabricated laminate, the abrasion resistance of the inorganic material layer was evaluated in the same manner as in Example 42. As a result, the critical load value was 63.9 mN. The results are shown in Table 4.

[0485] <Example 60>

[0486] Using polysiloxane compound 13, with PC as the resin substrate, after forming a cured product for inorganic material lamination on the PC as in Example 35, SiO2 was laminated by ion plating. For the fabricated laminate, the abrasion resistance of the inorganic material layer was evaluated in the same manner as in Example 42. As a result, the critical load value was 68.7 mN. The results are shown in Table 4.

[0487] <Comparative Examples 15 - 19>

[0488] Except for using M - 405 described in Reference Example 1 instead of the polysiloxane compound and using PMMA or PET as the resin substrate, laminates were fabricated in the same manner as in Comparative Example 5 or 6. These laminates had PC, PMMA, or PET as the resin substrate and SiO2 or ZrO2 as the inorganic material layer. In the same manner as in Example 42, the abrasion resistance of each inorganic material layer was evaluated. The results are shown in Table 4.

[0489] <Comparative Examples 20 - 24>

[0490] Except for not using M - 405 described in Reference Example 1, the abrasion resistance of each inorganic material layer was evaluated in the same manner as in Comparative Examples 15 - 19. The results are shown in Table 4.

[0491] (Table 2)

[0492]

[0493]

[0494] (Table 3)

[0495]

[0496] (Table 4)

[0497]

[0498]

[0499] As can be seen from Table 2, the inorganic matter layer-by-layer bottom coatings of the present disclosure all have good adhesion to the resin substrate and the inorganic matter layer. The adhesion (0 - 5) of Examples 1 to 35 to the inorganic matter layer is better than that of Comparative Examples 1 to 6 (6 - 12) when using a bottom coating without polysiloxane and Comparative Examples 7 to 12 (9 - 17) without using a bottom coating, showing excellent adhesion to various resin substrates and various inorganic matter layers.

[0500] In addition, as can be seen from Table 2, the bottom coating containing a polysiloxane compound having T units and D units as structural units has more excellent adhesion to the inorganic matter layer than the bottom coating containing a polysiloxane compound composed only of T units. This can be seen more clearly when comparing cases where all conditions except the polysiloxane compound are the same, for example, comparing Examples 1, 3, and 4 with Examples 5 - 10 and 13 - 15, comparing Examples 18 and 20 with Examples 21, 23, and 24, and comparing Comparative Example 29 with Example 30.

[0501] It should be noted that the adhesion of Example 16 to the inorganic matter layer is also "3", so it is excellent, but the adhesion is slightly worse than that of other substances having T units and D units. From this, it can be known that the value of x / (v + w + x + y) as the proportion of the D unit is preferably less than the ratio 0.69 of the polysiloxane compound 7 contained in Example 16.

[0502] As can be seen from Table 3, the inorganic matter layer-by-layer bottom coatings of the present disclosure still have good adhesion to the resin substrate and the inorganic matter layer even after warm water treatment. The adhesion (0 - 5) of Examples 36 to 41 to the inorganic matter layer is better than that of Comparative Example 13 (25) when using a bottom coating without polysiloxane and Comparative Example 14 (25) without using a bottom coating, showing excellent adhesion after warm water treatment.

[0503] As can be seen from Tables 2 to 4, the inorganic matter layer-by-layer bottom coatings of the present disclosure can both have good adhesion to the resin substrate and the inorganic matter layer and abrasion resistance of the inorganic matter layer of the laminate, with excellent practicality. This can be seen, for example, from the results of Example 42, which is the same laminate as Example 3 in Table 2, and Examples 43 to 60, which are its modification examples. In contrast, Comparative Examples 15 to 19 in Table 4 are all obtained by curing a curable composition containing a polyfunctional monomer without a polysiloxane compound. Although there are cases with high abrasion resistance, the adhesion to the inorganic matter layer is insufficient, so they are not practical. This can be seen, for example, from the results of Comparative Examples 15 and 18, which are the same laminates as Comparative Examples 5 and 6 in Table 2.

[0504] In addition, as can be seen from Table 4, the undercoat layer containing a polysiloxane compound having T units and D units as structural units has more excellent abrasion resistance of the inorganic material layer laminated thereon than the undercoat layer containing a polysiloxane compound composed only of T units. This can be seen more clearly when comparing cases where all conditions other than the polysiloxane compound are the same, for example, comparing Examples 42 to 44 with Examples 45 to 47, Comparative Examples 49 to 51 with Examples 52 to 54, and Comparative Example 57 with Example 58.

[0505] Therefore, the undercoat layer containing a polysiloxane compound having T units and D units as structural units is particularly excellent in both physical properties of adhesion to the inorganic material layer and abrasion resistance of the laminated inorganic material layer, and has more excellent practicality.

[0509] In addition, it can be used as a decorative printed film laminate, which is useful as a decorative film for display substrates, touch panels, thin films with transparent strip electrodes, lens sheets, optical waveguides, solar cell substrates, optical discs, various transparent substrates, etc.
