Problems solved by technology

However, many attempts have been made in recent years to use plastics instead of glass plates because glass plates have the following problems: they are fragile; they cannot be bent; they are not suitable for weight reduction due to their specific gravity; etc.
However, since the composition disclosed in Patent Document 4 contains sulfur, the material is easily discolored or degraded by heat, thus possibly impairing transparency

[0323] [Preparation Example 1] Preparation of Surface-Modified Silica Fine Particles (A-1)

[0324] As the silica fine particles (α) to be subjected to surface treatment, colloidal silica (silica fine particle content: 30% by mass, average particle diameter: 10-20 nm, trade name : IPA-ST, manufactured by Nissan Chemical Industries, Ltd.).

[0325] To a separable flask, add 100 parts of colloidal silica dispersed in isopropanol (amount includes solvent); to this separable flask, add 3 parts of gamma-methacryloxyoctyltrimethoxysilane (MOS) and 9 parts of phenyltrimethoxysilane (PhS) and mixed by stirring, further added 3.9 parts of hydrochloric acid with a concentration of 0.1825% by mass and stirred the mixture at 25° C. for 24 hours; (α) surface treatment, and then a dispersion containing the surface-modified silica fine particles (A-1) is obtained.

[0326] Loss of silane compound (herein, MOS) by hydrolysis was confirmed by gas chromatography (Model 6850; produced by Agi...

[0327] [Preparation Example 2] Surface-modified silica fine particles (A-2)

[0328] A dispersion containing surface-modified silica fine particles (A-2) was obtained in the same operation as in Preparation Example 1, except that in Preparation Example 1 for silica fine particles (α) The type and amount of each component of the surface treatment and the amount of hydrochloric acid became those shown in Table 1. The amounts added are summarized in Table 1.
