manufacture example 1

[0136]Silica coated titanium dioxide particle dispersion (S-1)

[0137] Add 350 parts by weight of titanium oxide micropowder coated with silicon oxide, 80 parts by weight of ethylene oxide-propylene oxide copolymer (average degree of polymerization is about 20), 1000 parts by weight of isopropanol and 1000 parts by weight of butyl cellosolve, The glass beads were dispersed for 10 hours, and the glass beads were removed to obtain 2430 parts by weight of a silica-coated titanium oxide particle dispersion (S-1). Here, the obtained silicon oxide-coated titanium oxide particle dispersion was weighed on an alumina dish, dried on a hot plate at 120° C. for 1 hour, and the total solid content concentration was determined to be 17% by weight. And the titanium oxide particle dispersion-1 coated with silicon oxide was weighed in a porcelain crucible, pre-dried on a hot plate at 80°C for 3 hours, and then fired in a muffle furnace at 750°C for 1 hour, and the obtained inorganic residue ...

[0139] Preparation of particles with silica as the main component

[0140] The solid content is 20% by weight, pH 2.7, the specific surface area obtained by the BET method is 226 square meters per gram, and the silanol concentration on the silica particles obtained by the methyl red adsorption method is 4.1×10 -5 Mole / g, water-dispersible colloidal silica (manufactured by Nissan Chemical Industry Co., Ltd., trade name: Snow-Tex) whose metal content in the solvent obtained by the atomic absorption method is Na4.6ppm, Ca0.013ppm, K0.011ppm -O) 30 kilograms are added to the tank, heated to 50 ° C, and the ultrafiltration membrane module (manufactured by トライテツツク) and the alumina ultrafiltration membrane (Nippon Barrier Co., Ltd. Manufactured by the company, trade name: ceramic UF element, specifications: diameter 4 mm, 19 holes, length 1 m, molecular weight cut off = 150,000, membrane area = 0.24 square meters) for concentration. After 0.5 hours, 10 kg of filtrate was discharged,...

[0143] Manufacture of silica particle sol

[0144] To 20 kg of methanol-dispersed colloidal silica prepared in Production Example 2, 0.6 kg of trimethylmethoxysilane (manufactured by Toray Douko-ning Co., Ltd.) was added, and stirred under heating at 60° C. for 3 hours. The number-average particle diameter determined by the dynamic light scattering method was 11 nanometers, and no change was found from before the treatment. The resulting methanol-dispersed hydrophobic colloidal silica has a specific surface area of ​​240 square meters per gram obtained by the BET method, and a silanol concentration of 2.1×10 on the silica particles obtained by the methyl red adsorption method. -5 mol / g.

[0145] After the above process is terminated, add 14 kg of methyl ethyl ketone (MEK), at a temperature of 50°C, a circulation flow rate of 50 liters / min, and a pressure of 1 kg / cm2, use the above-mentioned ultrafiltration membrane to concentrate and discharge 14 kg Filtrate, this operation ...

Abstract

A liquid resin composition comprising (A) a fluoropolymer, (B) a curable compound, (C) metal oxide particles having a number average particle diameter of 100 nm or less, and (D) a solvent. Once this composition is cured, metal oxide particles (C) can be segregated, the refractive index can be changed by 0.05 to 0.8 in the film thickness direction, and the cured material has a substantially two-layer structure of a low refractive index layer and a high refractive index layer. membrane.

Description

technical field [0001] The present invention relates to a liquid resin composition, a cured film, and a laminate, and more particularly, to a liquid resin composition, a cured film, and a laminate capable of forming a cured film having a low-refractive index layer and a high-refractive index layer through a single coating process. Background technique [0002] Now with the development of multimedia, various developments can be seen in various display devices (display devices). Moreover, in various display devices, especially for display devices for outdoor use centered on portable devices, the visibility is becoming more and more important, and it is easier to find this requirement of users in large display devices, so This requirement directly becomes a research topic. [0003] In the past, as a means of improving the visibility of a display device, an antireflection film made of a material with a low refractive index is coated on the substrate of the display device. As a ...
