[0003] JP 2015-120253 A
[0004] The present disclosure relates to a method for producing a laminate, comprising: step 1 of forming an intermediate layer (c) by vapor deposition on an antireflection layer of a substrate (s) having an antireflection layer; and step 2 of forming a water-repellent layer (r) on the intermediate layer (c); the intermediate layer (c) is a vapor-deposited layer of an organosilicon compound (C) having a silicon atom and an amino group and / or an amine skeleton; the water-repellent layer (r) is a cured layer of a mixed composition (ca) of an organosilicon compound (A) in which a monovalent group having a perfluoropolyether structure is bonded to the silicon atom with or without a linking group, and a hydrolyzable group is bonded to the silicon atom with or without a linking group; and the average vapor deposition rate when forming the intermediate layer (c) on the antireflection layer by vapor deposition is 0.2 nm / s or more and less than 1.2 nm / s.
[0005] The method for producing a laminate according to the present disclosure will be described in detail below. It is desirable for a laminate to exhibit excellent abrasion resistance in order to maintain water repellency, and there is a need for a production method that can produce a laminate exhibiting the above properties with high productivity. The method for producing a laminate according to the present disclosure can produce a laminate exhibiting excellent abrasion resistance with high productivity. In this disclosure, "productively producible" means that when a plurality of laminates are produced, the difference in abrasion resistance between the laminates is small. A small difference in abrasion resistance between the laminates means that a laminate exhibiting consistent properties can be stably produced, i.e., the productivity is excellent.
[0006] The following description of the constituent elements may be based on a representative embodiment of the present disclosure, but the present disclosure is not limited to such an embodiment. In this specification, a numerical range expressed using "to" means a range that includes the numerical values before and after "to" as the lower and upper limits.
[0007] Below, we will first explain each step of the manufacturing method of the present disclosure (hereinafter also referred to as the present manufacturing method), and then we will explain the laminate manufactured by the present manufacturing method (hereinafter also simply referred to as the laminate).
[0008] [Step 1] This production method includes Step 1, in which an intermediate layer (c) is formed by vapor deposition on the antireflection layer of a substrate (s) having an antireflection layer. The average vapor deposition rate when forming the intermediate layer (c) is 0.2 nm / s or more and less than 1.2 nm / s. The materials and components used in this step, as well as the procedure, are described below.
[0009] [Substrate (s) Having an Antireflection Layer] The material of the portion of the substrate (s) having an antireflection layer other than the antireflection layer (ar) is not particularly limited and may be either an organic material or an inorganic material, as long as the antireflection layer (ar) is provided on at least one side surface. Examples of organic materials include thermoplastic resins such as acrylic resins, polycarbonate resins, polyester resins, styrene resins, acrylic-styrene copolymer resins, cellulose resins, polyolefin resins, and vinyl resins (polyethylene, polyvinyl chloride, polystyrene, vinylbenzyl chloride resins, polyvinyl alcohol, etc.); and thermosetting resins such as phenolic resins, urea resins, melamine resins, epoxy resins, unsaturated polyesters, silicone resins, and urethane resins. Examples of inorganic materials include metals such as iron, silicon, copper, zinc, and aluminum, as well as alloys containing these metals, ceramics, and glass.
[0010] The laminate can be suitably used, for example, in eyeglass lenses. In this case, the substrate (s) having an antireflection layer is preferably one in which an antireflection layer (ar) is formed on a glass layer (sg) or a resin layer (sp). The antireflection layer (ar) is preferably formed at least on the intermediate layer (c) side. Examples of materials contained in the resin layer (sp) include allyl diglycol carbonate resin, polycarbonate resin, thiourethane resin, episulfide resin, etc. A primer layer and / or a hard coat layer may be formed between the glass layer (sg) or the resin layer (sp) and the antireflection layer (ar). The primer layer is a layer that improves the adhesion between the two layers laminated via the primer layer, and known materials can be used. The hard coat layer is a layer that imparts scratch resistance to the glass layer (sp) or the resin layer (sg) and exhibits a pencil hardness of H or higher according to the test method specified in JIS K5600. As the hard coat layer, known hard coat layers can be used, such as organic hard coat layers, inorganic hard coat layers, and organic-inorganic hybrid hard coat layers. The primer layer and hard coat layer can be formed, for example, by applying a precursor composition to a substrate and curing it, and the method for forming a water-repellent layer (r) described below can be used. The antireflection layer (ar) is a layer that has the function of preventing the reflection of incident light. Specifically, it is preferably a layer that exhibits reflective characteristics with a reflectance reduced to approximately 5.0% or less in the visible light region of 530 nm. The structure of the antireflection layer (ar) is not particularly limited, and it may be a single-layer structure or a multilayer structure. In the case of a multilayer structure, a structure in which low-refractive index layers and high-refractive index layers are alternately laminated is preferred. Examples of materials constituting the high-refractive index layer include oxides of titanium, zirconium, aluminum, tantalum, and lanthanum, and examples of materials constituting the low-refractive index layer include silica. The multilayer antireflection layer (ar) can be made of a material such as SiO 2 and ZrO 2 are alternately laminated, and the outermost layer opposite to the glass layer (sg) or resin layer (sp) is SiO 2The antireflection layer (ar) can be formed by, for example, a vapor deposition method.

[0070] The organosilicon compound (C) may be used alone or in combination of two or more.
[0071] [Procedure of Step 1] Step 1 is a step of forming an intermediate layer (c) by vapor deposition on the antireflection layer of a substrate (s) having an antireflection layer. The intermediate layer (c) is a vapor-deposited layer of an organosilicon compound (C) having a silicon atom and an amino group and / or an amine skeleton. The organosilicon compound (C) used for vapor deposition is as described above.
[0072] As the deposition method, a known method can be used, for example, a vacuum deposition method. In the vacuum deposition method, a deposition source is evaporated in a vacuum chamber and attached to the surface of a substrate. In the vacuum deposition method, the degree of vacuum during deposition is 1.0 × 10 -1 Pa or less, and 5.0 × 10 -2 Pa or less is more preferable, and 2.0 × 10 -2 The lower limit is not particularly limited, and is preferably 1.0 × 10 -4 Pa or higher in most cases.
[0073] Examples of methods for evaporating the deposition source in vacuum deposition include electron beam, resistance heating, heater heating, and induction heating, with the electron beam being preferred from the viewpoint of energy conversion efficiency. The output of the electron beam may be appropriately adjusted depending on the raw materials and substrate used, the deposition apparatus, the degree of vacuum, the irradiation area, and the average deposition rate, and a beam current of, for example, 6 to 36 mA is preferred.
[0074] The average deposition rate when vapor-depositing the organosilicon compound (C) onto the antireflection layer of the substrate (s) having an antireflection layer is 0.2 nm / s or more but less than 1.2 nm / s (0.20 nm / s or more but less than 1.20 nm / s), preferably 0.2 nm / s to 1.15 nm / s, and more preferably 0.2 nm / s to 1.1 nm / s. The average deposition rate is the value obtained by dividing the thickness of the vapor-deposited film by the deposition time required to form a vapor-deposited film of the above thickness (average deposition rate (nm / s) = film thickness (nm) / deposition time (s)). If the average deposition rate is 1.2 nm / s or more, abrasion resistance and productivity decrease, while if the average deposition rate is less than 0.2 nm / s, productivity decreases, which is undesirable.
[0075] [Intermediate layer (c)] The intermediate layer (c) is a vapor-deposited layer of the organosilicon compound (C). The vapor deposition method is as described above. The intermediate layer (c) has silicon atoms and an amino group or an amine skeleton (—NR 100 - and R 100 is a hydrogen atom or an alkyl group), and the intermediate layer (c) has an amino group or an amine skeleton. In a preferred embodiment, a hydrolyzable group or a hydroxy group is bonded to the silicon atom of the organosilicon compound (C), and Si-OH groups produced by hydrolysis of the Si-OH groups and / or the hydrolyzable groups bonded to the silicon atoms of the organosilicon compound (C) undergo dehydration condensation with each other, so that the intermediate layer (c) preferably has a condensation structure derived from the organosilicon compound (C). The intermediate layer (c) can function as a primer layer for the water-repellent layer (r).
[0076] The thickness of the intermediate layer (c) is, for example, about 1 to 1000 nm, preferably 5 nm or more, more preferably 10 nm or more, and even more preferably 20 nm, and is preferably 100 nm or less, more preferably 80 nm or less, and even more preferably 50 nm or less.
[0077] [Step 2] This production method includes Step 2, in which a water-repellent layer (r) is formed on the intermediate layer (c) obtained in Step 1. The water-repellent layer (r) is a cured layer of a mixed composition (ca) of an organosilicon compound (A) in which a monovalent group having a perfluoropolyether structure is bonded to a silicon atom via a linking group or not, and a hydrolyzable group is bonded to the silicon atom via a linking group or not. Among these, the mixed composition (ca) is preferably a mixed composition of an organosilicon compound (A) and an organosilicon compound (B) described below. The materials and procedures used in this step are described below.
[0078] <Organosilicon Compound (A)> The organosilicon compound (A) is a compound in which a monovalent group having a perfluoropolyether structure is bonded to a silicon atom via a linking group or not, and a hydrolyzable group is bonded to the silicon atom via a linking group or not. The water-repellent layer (r) is obtained by applying and curing the mixed composition (ca), and has a structure derived from the organosilicon compound (A). As described above, the organosilicon compound (A) has a hydrolyzable group bonded to a silicon atom (which may be bonded via a linking group), and the -SiOH groups (Si and OH may be bonded via a linking group) of the organosilicon compound (A) generated by hydrolysis undergo dehydration condensation, so the water-repellent layer (r) usually has a condensation structure derived from the organosilicon compound (A). Examples of the hydrolyzable group include an alkoxy group, a halogen atom, a cyano group, an acetoxy group, and an isocyanate group.
[0079] The perfluoropolyether structure can also be referred to as a perfluorooxyalkylene group. The perfluoropolyether structure has liquid repellency such as water repellency or oil repellency. The number of carbon atoms contained in the longest linear chain portion of the perfluoropolyether structure is, for example, preferably 5 or more, more preferably 10 or more, and even more preferably 20 or more. The upper limit of the carbon number is not particularly limited, and may be, for example, about 200. It is preferable that the monovalent group having a perfluoropolyether structure of the organosilicon compound (A) further has a perfluoroalkyl group at the free end.
[0080] The water-repellent layer (r) can also be shown as a layer having a perfluoropolyether structure and a polysiloxane skeleton, and preferably further has a perfluoroalkyl group. The water-repellent layer (r) preferably has a structure in which a monovalent group having a perfluoropolyether structure and a perfluoroalkyl group at the free end is bonded to a silicon atom of a part of the polysiloxane skeleton. The presence of the perfluoroalkyl group at the free end improves the water repellency of the water-repellent layer (r).
[0081] The number of carbon atoms in the perfluoroalkyl group (particularly the number of carbon atoms in the longest straight chain portion) is, for example, preferably 3 or more, more preferably 5 or more, and even more preferably 7 or more. There is no particular upper limit on the number of carbon atoms, and even a group of about 20 carbon atoms will exhibit excellent water repellency.
[0082] The perfluoroalkyl group may be bonded to a hydrocarbon group and / or a group in which at least some of the hydrogen atoms of the hydrocarbon group have been substituted with fluorine atoms to form a fluorine-containing group such as a fluoroalkyl group, for example, CF 3 (CF 2 ) m - (CH 2 ) n -, CF 3 (CF 2 ) m -C 6 H 4 - (wherein m is 1 to 10, preferably 3 to 7, and n is 1 to 5, preferably 2 to 4), and CF 3 (CF 2 ) m - (CH 2 ) n - (wherein m is 1 to 10, preferably 3 to 7, and n is 1 to 5, preferably 2 to 4) is preferred. It is more preferred that the perfluoroalkyl group is directly bonded to the perfluoropolyether structure.
[0083] In organosilicon compound (A), the monovalent group with perfluoropolyether structure and silicon atom can be bonded via suitable linking group, or the monovalent group with the above-mentioned perfluoropolyether can be directly bonded to silicon atom without this linking group.As linking group, for example, can be enumerated hydrocarbon group such as alkylene group, aromatic hydrocarbon group, (poly) alkylene glycol group, or the group in which part of their hydrogen atom is replaced by F or substituent, and the group in which these are suitably bonded.The carbon number of linking group is, for example, 1 or more and 20 or less, preferably 2 or more and 15 or less.
[0084] The hydrolyzable group functions to bond the organosilicon compounds (A) together or to bond the organosilicon compound (A) to active hydrogen (such as a hydroxyl group) on the surface of the substrate through a hydrolysis / dehydration condensation reaction. Examples of such hydrolyzable groups include alkoxy groups (particularly alkoxy groups having 1 to 4 carbon atoms), hydroxy groups, acetoxy groups, and halogen atoms (particularly chlorine atoms). Preferred hydrolyzable groups are alkoxy groups and halogen atoms, with methoxy groups, ethoxy groups, and chlorine atoms being particularly preferred.
[0085] The hydrolyzable group may be bonded to the silicon atom via a linking group, or may be bonded directly to the silicon atom without a linking group. The number of hydrolyzable groups bonded to the silicon atom may be one or more, and may be two or three, preferably two or three, and particularly preferably three. When two or more hydrolyzable groups are bonded to the silicon atom, different hydrolyzable groups may be bonded to the silicon atom, but it is preferable that the same hydrolyzable group is bonded to the silicon atom. The total number of fluorine-containing groups and hydrolyzable groups bonded to the silicon atom is usually four, but may be two or three (particularly three). When the number is three or less, the remaining bonds may be bonded to monovalent groups other than hydrolyzable groups, for example, alkyl groups (particularly alkyl groups having 1 to 4 carbon atoms), H, NCO, etc.
[0086] The monovalent group having a perfluoropolyether structure in the organosilicon compound (A) may be linear or may have a side chain, but is preferably linear.

[0161] <Solvent (D)> The mixed composition (ca) preferably contains a solvent (D). As the solvent (D), it is preferable to use a fluorine-based solvent, for example, a fluorinated ether solvent, a fluorinated amine solvent, a fluorinated hydrocarbon solvent, or the like can be used, and it is particularly preferable that the solvent has a boiling point of 100°C or higher. As the fluorinated ether solvent, hydrofluoroethers such as fluoroalkyl (particularly a perfluoroalkyl group having 2 to 6 carbon atoms)-alkyl (particularly a methyl group or an ethyl group) ether are preferred, for example, ethyl nonafluorobutyl ether or ethyl nonafluoroisobutyl ether can be mentioned. As the ethyl nonafluorobutyl ether or ethyl nonafluoroisobutyl ether, for example, Novec (registered trademark) 7200 (manufactured by 3M, molecular weight approximately 264) can be mentioned.

[0169] [Procedure of Step 2] Step 2 is a step of forming a water-repellent layer (r) on the intermediate layer (c) obtained in Step 1. As described above, the water-repellent layer (r) is a cured layer of the mixed composition (ca). The method of forming the cured layer is not particularly limited, and an example thereof includes a method of applying the mixed composition (ca) on the intermediate layer (c) obtained in Step 1, and then subjecting the applied mixed composition (ca) to a curing treatment.
[0170] The mixed composition (ca) can be prepared, for example, by mixing the respective components. The order and / or timing of mixing the respective components is not particularly limited, and for example, the organosilicon compound (A) and, if necessary, any optional components are sequentially added to a container, and then the mixture is stirred and mixed. Furthermore, when adding the respective components to the container, they may be added all at once, or may be added in portions over several times.
[0171] The stirring may be carried out using a known stirring device, for example, a mechanical stirrer, a magnetic stirrer, a homogenizer, or an ultrasonic disperser.
[0172] Examples of methods for applying the mixed composition (ca) to the intermediate layer (c) include dip coating, roll coating, bar coating, spin coating, spray coating, die coating, and gravure coating.
[0173] The method for applying the mixed composition (ca) is preferably a dip coating method from the viewpoint of productivity. The immersion time in the dip coating method may be appropriately adjusted depending on the mixed composition (ca) and the substrate, but is preferably 1 to 180 seconds, more preferably 5 to 60 seconds. The pull-up speed in the dip coating method may also be appropriately adjusted depending on the mixed composition (ca) and the substrate, but is preferably 1.0 to 10.0 mm / second, more preferably 2.0 to 6.0 mm / second.
[0174] Methods for curing the mixed composition (ca) applied to the intermediate layer (c) include, for example, drying and thermal curing. The curing method may be appropriately selected depending on the composition of the mixed composition (ca). For example, the water-repellent layer (r) can be formed by curing the mixed composition (ca) applied to the intermediate layer (c) by wet heating. The curing temperature is preferably 5°C or higher, more preferably 10°C or higher, and even more preferably 15°C or higher. It is also preferably 100°C or lower, more preferably 80°C or lower, and even more preferably 60°C or lower. The curing humidity is preferably 30% RH or higher, more preferably 50% RH or higher, even more preferably 60% RH or higher, and preferably 90% RH or lower, and even more preferably 85% RH or lower. The curing time is preferably 5 minutes or longer, more preferably 10 minutes or longer, and even more preferably 20 minutes or longer. It is also preferably 24 hours or shorter, more preferably 12 hours or shorter, even more preferably 6 hours or shorter, and particularly preferably 1 hour or shorter.
[0175] [Water-repellent layer (r)] The water-repellent layer (r) is a cured layer of the mixed composition (ca) of the organosilicon compound (A). As described above, the water-repellent layer (r) is obtained, for example, by applying and curing the mixed composition (ca), and has a structure derived from the organosilicon compound (A). The organosilicon compound (A) has a hydrolyzable group bonded to a silicon atom (which may be bonded via a linking group), and the -SiOH groups (Si and OH may be bonded via a linking group) of the organosilicon compound (A) generated by hydrolysis undergo dehydration condensation with each other, so the water-repellent layer (r) usually has a condensation structure derived from the organosilicon compound (A).
[0176] The thickness of the water-repellent layer (r) is, for example, 1 to 1000 nm.
[0177] [Step 3] The present production method preferably includes, before step 1, step 3, in which the antireflection layer of the substrate (s) having an antireflection layer is subjected to a hydrophilic treatment. Examples of hydrophilic treatment include corona treatment, plasma treatment, ultraviolet treatment, and ion cleaning treatment, with plasma treatment and ion cleaning treatment being more preferred. By performing a hydrophilic treatment such as plasma treatment, functional groups such as OH groups and COOH groups can be formed on the surface of the antireflection layer. When such functional groups are formed on the surface of the antireflection layer, the adhesion between the intermediate layer (c) and the substrate (s) having the antireflection layer can be particularly improved. Therefore, when step 3 is performed, step 1 is preferably a step of vapor-depositing an organosilicon compound (C) on the surface that has been subjected to the hydrophilic treatment. However, when the laminate is used for an eyeglass lens, it is preferable to vapor-deposit the organosilicon compound (C) without subjecting the antireflection layer of the substrate (s) to a hydrophilic treatment. Therefore, the hydrophilic treatment is preferably performed when the laminate is used for purposes other than eyeglass lenses.
[0178] [Manufacturing of Spectacle Lenses] The present manufacturing method is suitable for use in the manufacturing process of spectacle lenses. The present manufacturing method may be carried out in combination with or after other processes carried out on the laminate for manufacturing spectacle lenses. Examples of other processes include a edging process, a dyeing process, a shaping process, and an inspection process for the laminate. The laminate may be used as is as a spectacle lens.
[0179] [Laminate] The laminate produced by the present production method will be described. [Configuration of Laminate] The laminate comprises a substrate (s) having an anti-reflection layer, an intermediate layer (c) formed on the anti-reflection layer by vapor deposition, and a water-repellent layer (r) formed on the intermediate layer. The laminate may also include other components as long as they do not impair the effects of the present disclosure. Examples of other components include a primer layer, a hard coat layer, a protective film, and a hydrophobic resin film.
[0180] [Physical Properties of Laminate] After the abrasion resistance test described below is performed on the surface of the water-repellent layer (r) side of the laminate, the water contact angle and water sliding angle measured on the surface subjected to the abrasion resistance test preferably satisfy at least one of the following requirements (1) and (2), and more preferably satisfy both requirements (1) and (2): (1) The water contact angle is 110° or more. (2) The water sliding angle is 10° or less. The contact angle is also preferably 115° or more, and may be 130° or less. The sliding angle may be 0.5° or more.
[0181] The abrasion resistance test involves rubbing the surface of the water-repellent layer (r) of the laminate 20,000 times with a load of 200 g per 1.5 cm x 1.5 cm area. The rubbing is preferably performed with pulp paper, more preferably with pulp paper attached to an elastic body. Kimwipe S-200 manufactured by Nippon Paper Crecia Co., Ltd. is preferably used as the pulp paper. For example, Kimwipe S-200 is preferably used with the abrasion resistance test, with a stroke distance of 30 mm and a rubbing speed of 70 to 90 strokes per minute, and the contact angle and sliding angle are measured approximately at the center of the stroke area. When applying the load, it is sufficient to apply a pressure equivalent to a load of 200 g per 1.5 cm x 1.5 cm area. Laminates having a water-repellent layer (r) measuring less than 1.5 cm x 1.5 cm are also included within the scope of the present disclosure.
[0182] [Uses of Laminate] The laminate can be used in a variety of applications. When a spectacle lens substrate is used as the substrate, it can be suitably used as a spectacle lens. The laminate can also be preferably used as a front panel in a flexible display device, which is sometimes referred to as a window film. The flexible display device preferably comprises a laminate for a flexible display device and an organic EL display panel, with the laminate for a flexible display device being disposed on the viewing side of the organic EL display panel and configured to be foldable. The laminate for a flexible display device may further contain a polarizing plate (preferably a circular polarizing plate), a touch sensor, etc., and while these may be stacked in any order, they are preferably stacked in the order of window film (i.e., the laminate obtained by the present manufacturing method), polarizing plate, and touch sensor from the viewing side, or in the order of window film, touch sensor, and polarizing plate. The presence of a polarizing plate on the viewing side of the touch sensor is preferable because it reduces the visibility of the touch sensor pattern and improves the visibility of the displayed image. Each component can be stacked using an adhesive, pressure-sensitive adhesive, etc. The flexible display device may also include a light-shielding pattern formed on at least one surface of any one of the window film, the polarizing plate, and the touch sensor.
[0183] The present disclosure will be described in more detail below with reference to examples. The present disclosure is not limited to the following examples, and can of course be implemented with appropriate modifications within the scope of the invention, all of which are within the technical scope of the present disclosure.
[0184] Examples 1 to 4 and Comparative Examples 1 and 2 Preparation of Laminate Preparation of Substrate (s) Having Antireflection Layer A coating liquid was applied by immersion to the surface of Nikon-Essilor's NL3-SP (size 75 mmφ, center thickness 1.1 mm), followed by heat curing to laminate, in this order, a urethane-based impact resistance improving coat (primer layer) having a thickness of approximately 1 μm and a silicone-based scratch resistance improving hard coat (hard coat layer) having a thickness of approximately 2 μm. Next, a multilayer antireflection coat (corresponding to the antireflection layer (ar); a layer formed by alternating silica layers and zirconia layers) having a thickness of approximately 0.4 μm made of inorganic oxides (silica and zirconia) was formed by vacuum deposition on the hard coat layer to obtain a substrate (s) having an antireflection layer.
[0185] <Step 1> As the organosilicon compound (C), a reaction product of N-2-(aminoethyl)-3-aminopropyltrimethoxysilane and chloropropyltrimethoxysilane (trade name: X-12-5263HP, manufactured by Shin-Etsu Chemical Co., Ltd.), which is described in JP-A 2012-197330 and is represented by the following formula, was used.
[0186]
[0187] Using a vacuum deposition device (manufactured by Satisloh, model number 1200-DLX-2), the output of the electron beam was set so that the average deposition rate was the value shown in Table 1, and the vacuum was 1.0 × 10 -2 An organosilicon compound (C) was vapor-deposited onto the antireflection layer of a substrate (s) having an antireflection layer at 1000 Pa to form an intermediate layer (c) having a thickness of 15 to 35 nm. The average vapor deposition rate was calculated by dividing the thickness of the vapor-deposited film by the vapor deposition time required to form a vapor-deposited film of the above thickness (average vapor deposition rate (nm / s) = film thickness (nm) / vapor deposition time (s)). The above film thickness was measured using a quartz crystal film thickness meter calibrated to indicate the film thickness on the substrate.
[0188] <Step 2> OPTOOL (registered trademark) UF503 manufactured by Daikin Industries, Ltd. was used as the organosilicon compound (A), and FAS13E(C) was used as the organosilicon compound (B). 6 F 13 -C 2 H 4 -Si(OC 2 H5 ) 3 , manufactured by Tokyo Chemical Industry Co., Ltd.), and FC-3283 (C) as solvent (D). 9 F 21 A solution was prepared by mixing organosilicon compound (A) and Fluorinert (manufactured by 3M Co.), and the mixture was stirred at room temperature for a predetermined time to obtain a mixed composition (ca). In the mixed composition (ca), the proportion of the organosilicon compound (A) was 0.425% by mass, and the proportion of the organosilicon compound (B) was 0.05% by mass, when the entire mixed composition (ca) was taken as 100% by mass. The mixed composition (ca) was applied onto the intermediate layer (c) formed in step 1 above using a dip coater (DT-0001-S3, manufactured by SDI Co., Ltd.) under conditions of a liquid immersion time of 10 seconds and a pull-up speed of 3.5 mm / sec. Thereafter, wet heat curing was performed at 50°C and 80% RH for 30 minutes to form a water-repellent layer (r), which is a cured layer of the mixed composition (ca).
[0189] [Evaluation] The laminates obtained in the examples and comparative examples were evaluated by the following methods.
[0190] On the water-repellent layer (r) of the laminate, 16 sheets of Kimwipe Wiper S-200 manufactured by Nippon Paper Crecia Co., Ltd. were attached to a 15 mm square elastic body (plastic eraser model number 1156SMTR00 manufactured by Maped (France)), and a 200 g load was applied, 30 mm stroke, 90 r / min (90 back and forth per minute) 20,000 times rubbing abrasion resistance test was performed. Then, at the approximate center of the abrasion site, the water contact angle and water sliding angle after the abrasion resistance test were measured by the following method. A 1 μL water droplet was dropped on the water-repellent layer (r) of the obtained laminate, and a contact angle measurement device (manufactured by Kyowa Interface Science Co., Ltd., DM-500 / DM-SA) was used to measure the water contact angle by the sessile drop method (analysis method: ellipse fitting method). A 20 μL drop of water was dropped onto the water-repellent layer (r) of the obtained laminate, and the sliding angle of the water was measured using a contact angle measuring device (DM-500 / DM-SA, manufactured by Kyowa Interface Science Co., Ltd.) by the sliding method (analysis method: perfect circle fitting method, tilt method: continuous tilt, sliding detection: before sliding, movement judgment: forward and backward, sliding judgment distance: 10 dots).
[0191] For each of the laminates prepared under the conditions described in Examples 1 to 4 and Comparative Examples 1 and 2, the water contact angle and water sliding angle were measured after the abrasion resistance test. After the abrasion resistance test, samples that satisfied both of the following requirements (1) and (2) were judged to be good products with excellent abrasion resistance, and samples that did not satisfy at least one of the requirements were judged to be defective. (1) The water sliding angle after the abrasion resistance test was 10° or less. (2) The water contact angle after the abrasion resistance test was 110° or more.
[0192] The rate of non-defective products among the three samples evaluated was taken as the rate of non-defective products and calculated (rate of non-defective products (%) = number of non-defective samples / number of measured samples × 100). A higher rate of non-defective products indicates higher abrasion resistance and higher productivity of the laminate.
