Since the cerium oxide particles have voids inside, the refractive index is lower than that of the solid particles. The refractive index of the particles is 1 to 40 or less, preferably 1.35 or less, and more preferably 1.3 or less. The reason why the refractive index is 1.40 or less is that even if the addition ratio exceeds 1.40, the curing which is excellent in antireflection property cannot be obtained. Further, the antireflection performance is preferably as low as the lower limit of the refractive index of 1. 使用 When the hollow particles are used, the strength of the particles is lowered due to the low refractive index, and the hardness or scratch resistance of the cured film is lowered. Therefore, the refractive index is preferably 1.20. The "refractive index" in the present specification means the refractive index of the Na-D line (589 μm) at 25 °C. In the present specification, the "refractive index of particles" in the same matrix makes the content of the particles in the solid component 1% by mass.

Isopropyl alcohol solvent), "JX1 009SIV" (number average particle diameter 50 nm obtained by a transmission electron microscope, refractive index 1.29, solid content 20 mass%, methyl isobutyl ketone solvent). The hollow cerium oxide particles used in the embodiment may be modified by a particle modifier. The particle modifier is exemplified by a compound having a polymerizable unsaturated group and a hydrolyzable decyl group (hereinafter also referred to as "polymerizable particle modifier"). The polymerizable unsaturated group of the polymerizable particle modifier is exemplified by a vinyl group or a (meth) acrylonitrile group. Further, the hydrolyzable decyl group means a group which reacts with water to form a stanol group (S i - Ο Η ), for example, a fluorene-bonded one or more methoxy groups, ethoxy groups, n-propoxy groups, and isopropyloxy groups. An alkoxy group such as a group or a n-butoxy group, an aryloxy group, an ethoxy group, an amine group or a halogen atom. A commercially available product such as methacryloxypropyltrimethoxydecane may be used as the polymerizable particle modifier used in the embodiment, and for example, a compound described in International Publication WO097/12942 may be used. Further, as the particle modifier, a compound having a fluorine-containing hydrolyzable 矽 18 · 201127919 alkyl group (hereinafter also referred to as "fluorine-containing particle modifier") may be used. When a fluorine-containing particle modifier is used, the hollow ceria particles can be efficiently obtained. A commercially available product such as tridecafluorooctyltrimethoxydecane can be used as the fluorine-containing particle modifier used in the embodiment. Further, a particle modifier having an alkyl group or a particle modifier having an anthrone may be used in the same manner as the fluorine-containing particle modifier. The above various particle modifiers may be used singly or in combination of plural kinds. In order to modify the hollow cerium oxide particles used in the present embodiment, it is preferred to mix the hollow cerium oxide particles and the particle modifier to bond the two by hydrolysis. The ratio of the organic polymer component in the obtained reactive hollow ceria particles, that is, the hydrolyzate of the hydrolyzable decane to the condensate is usually a constant amount of % by weight of the dry powder when it is completely burned in the air, for example, It can be obtained in the air by thermogravimetric analysis from room temperature to usually 800 °C.

According to the method for producing the antireflection laminate, the curable composition satisfying the above conditions can be applied to the substrate once and hardened, and the surface which is in contact with the substrate is formed on the opposite side to have a high density. A layer of particles having a refractive index of 1.40 or less. According to this, it is possible to produce an antireflection laminate which has both scratch resistance and low refractive index. Each step is explained below. 2 · 1 · 1 · Step (a) Step (a) is a step of preparing the aforementioned curable composition. Since the constitution, manufacturing method, and the like of the curable composition are as described above, detailed descriptions thereof will be omitted. 2.1.2. Step (b) Step (b) is a step of hardening the hardenable composition prepared in the step (a) after it is applied to a substrate. The method of applying the curable composition prepared in the step (a) to the substrate is not particularly limited, and for example, coating bar coating, air knife coating, -24 - 201127919 gravure coating, concave plate reverse roller can be used. Conventional methods such as coating, reverse roll coating, lip coating, die coating, dip coating, lithography, flexographic printing, screen printing, and the like. The curing condition of the hardening composition is not particularly limited, but the curable composition may be applied to various substrates such as a triethylenesulfonyl cellulose resin substrate or a polyethylene terephthalate substrate. Make the hardener. Specifically, the curable composition may be applied, and it is preferred to dry the volatile component at 0 to 200 ° C and then perform radiation treatment and/or heat hardening to form an antireflection layer. The preferable conditions for the heat hardening are carried out at a temperature of from 20 ° to 150 ° C in the range of from 1 sec to 24 hours. When hardening with radiation, it is preferred to use ultraviolet rays or electron beams. The amount of ultraviolet light is preferably 0.01 to 1 〇 J/cm 2 , more preferably 0 1 to 2 J/cm 2 . Further, the irradiation conditions of the electron beam are a pressurization voltage of 1 〇 to 3 〇〇 kV ' electron density of 0.02 to 0.30 mA/cm 2 and an electron beam irradiation amount of 1 to i 〇 Mrad. 2.2. Antireflection laminate The antireflection laminate of the present embodiment is produced by the method for producing an antireflection laminate. Fig. 1 is a cross-sectional view schematically showing a laminate for antireflection of the present embodiment. As shown in FIG. 1, the antireflection laminate 100 of the present embodiment is formed by curing the curable composition on the substrate 形成0 to form a cured film 20, and the cured film 20 is in contact with the substrate 10. The hard layer 24 in which the particles 22 are substantially absent is formed on the surface side, and the low refractive index layer 2 6 in which the particles 2 2 are present at a high density is formed on the surface opposite to the surface in contact with the substrate. In the cured film 20, a portion other than the particles (hereinafter also referred to as "matrix") is obtained by hardening the component other than the component (B) of the curable composition, and the hydroxyl group concentration and carboxyl group in the matrix of jg - 25 - 201127919 The total concentration, the phosphate group concentration, and the base concentration are preferably 0.5 mmol/g or more and 15 mmol/g or less. Hereinafter, each layer of the antireflection laminate of the present embodiment will be described. 2.2.1. Base material The type of the substrate 10 used for the antireflection laminate of the present embodiment is not particularly limited, and examples thereof include triethyl fluorenyl cellulose resin, polyethylene terephthalate resin, and poly A carbonate resin, a polyester resin, an acrylic resin, glass, or the like. Among these, a substrate composed of a triethyl fluorenyl cellulose resin or a polyethylene terephthalate resin is preferred. By forming the antireflection laminate containing the substrates, the component (A1) contained in the curable composition can be easily pulled to the vicinity of the substrate. In particular, when the substrate is a triethylenesulfonyl cellulose resin and 2-hydroxyethyl (meth)acrylate is contained as the component (A1), the effect is remarkably exhibited. According to this, the low refractive index layer 26 in which the particles 22 are present at a high density can be formed on the opposite side to the surface in contact with the substrate. In addition, by making the antireflection laminate containing the substrates, it is possible to apply a wide range of hard coatings such as a lens portion of a camera, a screen display portion of a television (CRT), or a color filter in a liquid crystal display device. Excellent scratch resistance and anti-reflection effects are obtained in the field of use of layers and/or anti-reflection films. 2.2.2. Hard coat layer The hard coat layer 24 is formed in a cured film 20 having a two-layer structure obtained by hardening the above-mentioned curable composition, and is formed of a layer substantially free of particles 22 -26-201127919. The thickness of the hard coat layer 24 is not particularly limited 'better than 1 to 5 Μ01' and more preferably 1 to 10 μm, because the thickness of the hard coat layer 24 is less than Ιμηι, and there is no possibility of increasing the density of the substrate. In the case where the 'other aspect' exceeds 50 μm, it is difficult to form a uniform film. 2.2.3. Low-refractive-index layer The low-refractive-index layer 26 is composed of a layer having a two-layer structure in which a cured film having a two-layer structure obtained by curing the curable composition is formed of a layer having particles 22 at a high density. The thickness of the low refractive index layer 26 is not particularly limited, but is preferably 50 to 200 nm, more preferably 60 to 150 nm, and most preferably 80 to 120 nm. The reason for this is that when the thickness of the low refractive index layer 26 is less than 50 nm, sufficient antireflection effect cannot be obtained. On the other hand, when the thickness exceeds 200 nm, the antireflection effect is lowered. The difference in refractive index between the hard coat layer 24 and the low refractive index layer 26 in the antireflection laminate of the present embodiment is preferably 0.05 or more. The reason for this is that when the refractive index difference between the hard coat layer 24 and the low refractive index layer 26 is less than 〇5〇, the synergistic effect of the antireflection films cannot be obtained, and the antireflection effect is lowered. 3.
