When the amount of the component (C) is less than 1% by weight, the scratch resistance of the obtained cured coating film may not be obtained. On the other hand, if it exceeds 15% by weight, the refractive index is lowered. (D) Compound which initiates active species by irradiation with an active energy ray A compound which induces an active species by irradiation with an active energy ray (hereinafter referred to as "(D) component") may be added to the composition of the present invention.

The compounding amount of the component (D) in the composition of the present invention is not particularly limited. The total amount of the composition excluding the organic solvent is 100% by weight. /. The case is preferably in the range of 〇~15 wt%, more preferably 2-8 wt%, and most preferably 3% wt%, and if it exceeds 15 wt%, the hardness may be lowered. (E) Organic solvent The composition of the present invention may contain an organic solvent. By containing an organic solvent, a uniform anti-reflection film of a film can be formed. As for the organic solvents, exemplified are ketones such as acetone, methyl isobutyl ketone, methyl ethyl ketone, cyclohexanone, and methyl amyl ketone, ethyl acetate, butyl acetate, and propylene glycol monomethyl ether.

Among these, ketones such as acetone, methyl isobutyl ketone, methyl ethyl ketone, cyclohexanone, and methyl amyl ketone are preferred, and ethyl acetate, butyl acetate, and propylene glycol monomethyl ether acetate are preferred. Ester and other esters; propylene glycol monomethyl ether, methanol, ethylene -27-200902622 alcohol, second butanol, third butanol, 2-propanol, isopropanol and other alcohols, more preferably methyl isobutyl A single one or a combination of two or more of a ketone, methyl amyl ketone, and a third butanol. As the organic solvent, a dispersion medium of the reactive particles of the above component (A) may be used, and it may be further used in combination with other organic solvents. The amount of the organic solvent to be blended is not particularly limited, and the total amount of the composition excluding the organic solvent is 100 parts by weight, preferably 1 Torr to 1 〇 〇, 〇 〇 0 parts by weight. The reason is that when the amount of the organic solvent is less than 10 parts by weight, it is difficult to adjust the viscosity of the curable composition. On the other hand, if it exceeds 100 parts by weight, the curable composition is present. The preservation stability is lowered or the viscosity is lowered, making the operation difficult. (F) Additive The composition of the present invention preferably contains a photosensitizer, a polymerization inhibitor, a polymerization initiator, a leveling agent, a wet modifier, and an interface within a range not impairing the object and effect of the present invention. Additives such as active agents, plasticizers, ultraviolet absorbers, antioxidants, antistatic agents, decane coupling agents, inorganic filling agents, pigments, dyes, and the like. (2) Modification method of the composition of the present invention The composition of the present invention can be mixed at room temperature or under heating, by separately adding the composition containing the above components (A) to (D) and the above (E) as needed Prepared by ~(F) ingredients. Specifically, it can be prepared by using a mixer such as a kneader, a kneader, or a ball mill 'three-roller drum. (3) Hardening conditions of the composition of the present invention The composition of the present invention can be hardened by heat and/or radiation (light). If -28-200902622 is a hot case, the heat source can use, for example, an electric heater, an infrared lamp, a hot air or the like. In the case of the radiation (light), the radiation source is not particularly limited as long as the composition can be cured for a short period of time after application. For example, as the infrared radiation source, a lamp, a resistance heating plate, and a lightning can be cited. For example, there are sunlight, lamps, fluorescent lamps, lasers, etc., and radiation sources of ultraviolet rays, such as mercury lamps, halogen lamps, lasers, etc., and electron beams. Examples of the radiation source include a cold cathode method in which a high-voltage pulse is generated by a metal by using a commercially available tungsten wire, and a secondary cathode method in which an ionized gaseous molecule and a metal are generated by collision. Electronic way. Further, examples of the radiation source of the ray, the /3 ray, and the r ray include a nuclear cleavage material such as c 〇 6 (), and a vacuum tube which accelerates electrons against the anode in the r ray system. These radiations may be irradiated one by one or two or more simultaneously or during a fixed period. As for the conditions by heat hardening, it is preferred to heat at a temperature in the range of 30 to 200 ° C for 1 to 180 minutes. By such heating, the base material is not damaged, and the antireflection film excellent in scratch resistance can be obtained more effectively. Further, for these reasons, it is preferably heated at a temperature in the range of 50 to 180 ° C for 2 to 120 minutes, preferably at a temperature in the range of 80 to 150 ° C for 5 to 60 minutes. The condition for subsequent radiation irradiation is preferably such that the exposure amount becomes in the range of 0.01 to 10 J/cm 2 . The reason is that if the exposure amount is less than 〇1 J/cm2, there is a case where the curing is poor. On the other hand, if the exposure amount exceeds 1 〇J/cm2, there is a case where the curing time -29-200902622 is abnormal. Further, for these reasons, the preferable exposure amount 値 is in the range of 0.1 to 5 J/cm 2 , more preferably in the range of 〇 3 to 3 J/cm 2 . II. Cured film and laminate The cured film of the present invention is composed of a cured product obtained by hardening the above-described composition of the present invention, and the cured film of the present invention can be used as a high refractive index because of its high refractive index and antistatic property. Antistatic layer. The laminate of the present invention contains a layer composed of the cured film of the present invention. The layer composed of the cured film of the present invention is a layer having a function of a high refractive index layer and/or an antistatic layer. Further, in the case where the laminate of the present invention is an antireflection film, a low refractive index layer, a hard coat layer, a substrate, or the like may be contained in addition to the above layer. Figure 1 shows a cross-sectional view of the antireflection film. As shown in FIG. 1, on the substrate 2, a hard coat layer 3, a high refractive index layer 4, and a low refractive index layer 5 are laminated. At this time, on the substrate 2, the high refractive index layer 4 may be directly formed instead of the hard coat layer 3. Further, a medium refractive index layer 6 (not shown) may be provided between the hard coat layer 3 and the high refractive index layer 4. (1) Low refractive index layer The curable composition for forming the low refractive index layer is not particularly limited, and a conventional material for forming a low refractive index layer can be used. The refractive index of the low refractive index layer (the refractive index of the Na-D line, the measurement temperature of 25 ° C) is preferably 1.50 or less. The reason is that when the refractive index of the low refractive index film exceeds 1,500, the antireflection effect is remarkably lowered. Accordingly, the refractive index of the low refractive index film is preferably 1.48 or less, more preferably 1.45 or less. -30- 200902622 Further, in the case of providing a plurality of low-refractive-index films, as long as at least one of the layers has a refractive index 上述 within the above range, the refractive index 其他 of the other low-refractive-index films may be more than 丨·50. . The thickness of the low refractive index layer is not particularly limited, but is preferably, for example, 50 to 200 nm. The reason for this is that if the thickness of the low refractive index layer is less than 50 nm, the antireflection effect may not be sufficiently obtained. On the other hand, if the thickness exceeds 200 nm, light interference may occur to reduce the antireflection effect. Therefore, the thickness of the low refractive index layer is more preferably from 50 to 250 nm, and further preferably from 70 to 150 nm. (2) High refractive index layer The high refractive index layer is composed of a cured film obtained by curing the composition of the present invention. Since the high refractive index layer also has antistatic properties, the dustproofness of the laminate can be improved. In the constitution and the like of the composition of the present invention, the above description is well known, and the detailed description thereof will be omitted. Hereinafter, the high refractive index layer and the thickness will be described. The refractive index of the high refractive index layer is preferably 1.57 or more, more preferably 1.58 or more, and most preferably 1.59 or more. If the refractive index of the high refractive index layer is less than 1.57, sufficient antireflection may not be obtained. Further, the difference in refractive index between the low refractive index layer and the low refractive index layer is preferably 0.16 or more, more preferably 〇1.7 or more. The difference in refractive index between the high refractive index layer and the low refractive index layer may not be sufficient to achieve an antireflection effect if it does not reach 〇 · 1.6. The thickness of the high refractive index layer is not particularly limited, and is, for example, preferably from 50 to 30,000 nm. The reason is that if the thickness of the high refractive index layer is less than 50 nm, -31 - 200902622 may have an antireflection effect or a decrease in the adhesion to the substrate when combined with the low refractive index layer. When the thickness exceeds 30,000 nm', light interference is generated and the antireflection effect is lowered. Accordingly, the thickness of the high refractive index layer is more preferably from 50 to 1,000 nm, and even more preferably from 60 to 500 nm. Further, in order to obtain a higher antireflection property, when a plurality of high refractive index layers are provided to have a multilayer structure, the thickness of the plurality of high refractive index layers may be 50 to 30,000 nm in total. Further, in the case where a hard coat layer is provided between the high refractive index layer and the substrate, the thickness of the high refractive index layer may be 50 to 300 nm. (3) Hard coat layer The constituent material of the hard coat layer used in the antireflection film of the present invention is not particularly limited. As the materials, a single or a combination of two or more of a decyl alkane resin, an acrylic resin, a melamine resin, and an epoxy resin is exemplified. Further, the thickness of the hard coat layer is not particularly limited, and is preferably from 1 to 100 μm, more preferably from 3 to 30 μm. The reason is that if the hard coat layer does not reach Ιμηι, the hardness is lowered as a hard coat layer. On the other hand, if the thickness exceeds 100 μm, the base material is deformed by hardening and shrinking of the hard coat layer. The situation. (4) Substrate The type of the substrate used for the antireflection film of the present invention is not particularly limited, and examples thereof include glass, polycarbonate resin, polyester resin, acrylic resin, and polyethylene terephthalate. A substrate composed of an alcohol ester resin (PET), a triacetyl cellulose resin (TAC) or the like. By using anti-32-200902622 reflective film containing these substrates, a wide range of anti-reflection film applications 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 anti-reflection effect in the field. The invention is specifically described by the following examples, which are not intended to limit the invention in any way. In addition, "%" and "parts" mean % by weight and parts by weight unless otherwise stated.

On the contrary, in Comparative Example 1, in which the particle diameter of the reactive particles was as small as 5 9 nm, the surface resistance was high and the scratch resistance was deteriorated. On the other hand, in Comparative Example 2 in which the particle diameter of the reactive particles was as large as 8.9 nm, the haze property was high and the highest reflectance was low. Further, it can be seen that Comparative Examples 3 and 4 which do not contain the component (B) have the lowest partial reflectance. [Industrial Applicability] The curable composition of the present invention can be used for producing a cured film excellent in high refractive index, antistatic property, and scratch resistance. The cured film of the present invention can be used as a coating film which requires antistatic property and scratch resistance, and can be used as a high refractive index antistatic layer of an antireflection film. -39-200902622 BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic view showing an embodiment of a laminate (antireflection film) of the present invention.
