Embodiment

[0111] Hereinafter, the present invention will be described in more detail through examples. First, the content of the test implemented for evaluating the characteristic of the sample (glass plate with an ultraviolet shielding film) produced in each Example and a comparative example is demonstrated.

[0112]

[0113] Optical properties were measured using a spectrophotometer (manufactured by Shimadzu Corporation, UV-3100PC). The measured transmittance is the transmittance at wavelengths of 550nm and 1550nm, the visible light transmittance YA, the ultraviolet transmittance TUV380 calculated according to ISO9050 (1990 edition), and the ultraviolet transmittance TUV400 calculated according to ISO13837 (convention A). In addition, TUV380 is a value calculated based on the transmittance of the light beam in wavelength 280nm-380nm, and TUV400 is a value calculated based on the transmittance of light beam in wavelength 300-400nm. In addition, the haze was measured using HZ-1S manu...

Embodiment A1

[0119] Prepared to include R in formula (4) 1 and R 2 All 1,1,3,3-tetramethylbutyl benzotriazole-based ultraviolet absorbers ("TINUVIN360" manufactured by CIBA SPECIALTY CHEMICALS, INC.; organic compound α) were used as dispersants, and water was used as the dispersant. Dispersion liquid of medium (10% by weight of ultraviolet absorber content, average particle diameter of 110 nm). In addition, the said benzotriazole type ultraviolet absorber used the ultraviolet absorber which mixed with the zirconia bead in advance with the paint conditioner (paint conditioner), and pulverized to the said average particle diameter. Pure water, ethanol (manufactured by Katayama Chemical Co., Ltd.), triol obtained by adding propylene oxide to glycerin (G-300 manufactured by ADEKA Corporation; average molecular weight 300; organic compound B), tetraethoxysilane (TEOS; Shin-Etsu Chemical Co., Ltd.), concentrated hydrochloric acid (manufactured by Kanto Chemical Co., Ltd.; 35% by mass) and the ...

Embodiment A2～A12

[0123] A glass plate with an ultraviolet shielding film was obtained in the same manner as in Example A1 except that the concentration of each component in the forming solution and the average particle diameter of the ultraviolet absorber were changed as shown in Table 1. It should be noted that for Examples A8 to A12, glycidoxypropyltrimethoxysilane (GPTMS; 3-glycidoxypropyltrimethylsilane) was further added as a silane coupling agent to the forming solution. Oxysilane; manufactured by Shin-Etsu Chemical Co., Ltd.).

Abstract

This ultraviolet ray shielding film contains silicon oxide and microparticles of an organic compound (A) having a solid form at ambient temperature and having a molecular weight of 5000 or less, wherein the microparticles have an average particle diameter of 150 nm or less. The glass article has, for example, an ultraviolet ray transmittance (TUV380) of 2% or less, and preferably also has a transmittance (T550) for light having a wavelength of 550 nm of more than 70%. The ultraviolet ray shielding film may additionally contain an organic compound (B) such as a polyether compound and a polyol compound. The ultraviolet ray shielding film has excellent long-term ultraviolet ray shielding performance.

Description

technical field [0001] The present invention relates to a glass article comprising a glass plate and an ultraviolet shielding film formed thereon. In addition, the present invention relates to a fine particle dispersion composition for forming an ultraviolet shielding film. Background technique [0002] Glass panels are required to have the properties of transmitting visible light and shielding ultraviolet rays. In particular, in window glass applications, there is an increasing demand for a glass plate to which an ultraviolet shielding function (ultraviolet shielding ability) is added from the viewpoint of sun protection and the like. Therefore, iron (III; Fe 2 o 3 ) A glass plate with a ratio of inorganic components that absorb ultraviolet rays. [0003] When only adjusting the composition of the glass plate, there is a limit to the shielding of ultraviolet rays, so it has been proposed to form a film (ultraviolet shielding film) having ultraviolet shielding ability on...
