Problems solved by technology

[0004] However, according to conventional methods, the achievable refractive index is limited, and heat resistance, weather resistance, etc. are lowered
Furthermore, even after the curing step, outgassing continues to occur under high temperature conditions, which causes problems when fabricating devices
Although there is known a method of using metal oxide as a material capable of imparting a high refractive index, if the amount of the metal oxide exceeds a certain level, it aggregates in the cured product, causing light scattering and seriously deteriorating transparency
In addition, stable dispersion of metal oxide particles cannot be maintained, and the particles tend to sink

Embodiment 1

[0114] A silicone resin was prepared by sol-gel polymerizing 300 mmol of methyltrimethoxysilane and 300 mmol of tetramethoxysilane in the presence of an acid catalyst. Then, 2 g of the prepared resin and 8 g of poly(dibutyltitanate) (polymerization degree: n=4) were dissolved in 10 g of ethylene glycol diethyl ether to prepare a curable composition. Then, the composition was spin-coated and cured at a temperature of 200° C. for 30 minutes, thereby forming a high-refractive film.

Embodiment 2

[0116] In addition to using 8g of di-n-butoxide ethyl acetate (titanium di-n-butoxide (bis-2,4-pentanedionate)) instead of poly (butyl titanate), in the same manner as in Example 1 A high refractive film was prepared in the same manner as described.

Embodiment 3

[0118] A high refractive film was prepared in the same manner as described in Example 1 except that 8 g of zirconium tert-butoxide was used instead of poly(butyl titanate).

Abstract

The present application relates to a composition having high refraction. The composition of the present application exhibits excellent transparency, moisture resistance, heat resistance, water resistance, weather resistance, light resistance and durability, and enables the formation of a highly refractive film having a high refractive index. The composition exhibits little outgassing during or after processing, and can be applied using a solution application method, and thus can be effectively used in a variety of electronic optical devices.

Description

technical field [0001] This application relates to a high refractive composition. Background technique [0002] High-refractive resins can be used for optical elements that require anti-reflection effects, light-scattering effects, or light-extraction effects. For example, high-refractive resins can be used for plastic optical lenses, high-precision lenses for optical disk recording, prisms, optical fibers, optical waveguides, optical adhesives, optical semiconductor packages, or functional materials such as anti-reflection films, light-scattering films . A viewing angle increasing film; a brightness improving film or a filter, which can be applied to a PDP (Plasma Display Panel) or an LCD (Liquid Crystal Display). In addition, the high refractive resin can be used as an additive for preventing plastic deterioration, as an additive for cosmetics, or as a window glass for vehicles, and the like. [0003] As methods for producing high refractive resins, a method of introduci...
