Embodiment 1

[0173] Preparation of transparent film-forming paint (A-1)

[0174] Use silica-based hollow fine particle dispersion gel (manufactured by Catalyst Chemical Industry Co., Ltd.: Sul-ria 1420, average particle diameter 60nm, concentration 20.5% by weight, dispersion medium: isopropanol, particle refractive index 1.30) as the low refractive index Element. 10 g of perfluorooctylethyl triethoxysilane (AY43-158E 100% manufactured by Toray Dou Corning) was mixed into 100 g of this gel, and 10 g of ultrapure water was added, and stirred at 40° C. for 5 hours to obtain a surface-treated gel. Silica-based hollow fine particle dispersion gel (solid content: 19.3% by weight).

[0175] The surface charge of the surface-treated silica-based hollow fine particle dispersion gel was measured and found to be 8.3 µeq / g. In this surface-treated silica-based hollow particle dispersion gel 15.5 g and hexaerythritol tripentaacrylate (hexaerythritol tripentaacrylate) (Nippon Kayaku Co., Ltd.: KAYA...

[0196] Preparation of transparent film-forming paint (A-2)

[0197] Use silica-based hollow fine particle dispersion gel (manufactured by Catalyst Chemical Industry Co., Ltd.: Sul-ria 1420, average particle diameter 60nm, concentration 20.5% by weight, dispersion medium: isopropanol, particle refractive index 1.30) as the low refractive index Element. In this gel 100g, 7.11g of tetraethyl orthosilicate (manufactured by Tama Chemical Co., Ltd. 28SiO 2component 28.8%), 10 g of ultrapure water was added, and stirred at 40°C for 5 hours to obtain a surface-treated silica-based hollow fine particle dispersion gel (solid content 19.3%). The surface charge of the surface-treated silica-based hollow fine particle dispersion gel was measured and found to be 18.3 μeq / g. 15.5 g of gel, 24 g of pentaerythritol triacetate (Kyoeisha Chemical Co., Ltd.: PE-3A) and 24 g of diethylaminoethyl methacrylate (Kyoeisha Chemical Co., Ltd.) were dispersed into the surface-treated silica-based hol...

Abstract

The present invention provides a transparent capsule forming paint which can coat one kind of paint for one time to form a transparent capsule with more than two functions. The present transparent capsule forming paint is the transparent capsule forming paint including the following components, (A) a metallic oxide small particle (A), the surface of the small particle is treated by the organosilicon compound and / or the multiple function acrylate resin with hydrophobicity function group, and the surface electric charge amount (QA) is at the scope from 5 to 80 mu eq / g; (B) a stroma forming component which includes a hydrophobic stroma forming component, and the hydrophobic forming component includes organosilicon compound or its hydrolysate, hydrolytic polycondensate, and / or a multiple function (methyl) acrylate resin with hydrophobic functional groups; (C) a polar solvent. Wherein, the concentration (CPA) of the metallic small particle (A) which acts as solid component is in the scope from 0.1 to 20 weight percentage, and the concentration (CM) of the stroma forming component (C) which acts as solid component is in the scope from 1 to 50 weight percentage.

Description

technical field [0001] The present invention relates to a transparent film-forming paint and a substrate with a transparent film formed using the transparent film-forming paint. The transparent film-forming paint can form a transparent film having at least two or more functions by applying one paint once. Such as anti-reflection function, hard coat function. Background technique [0002] Conventionally, in order to improve the scratch resistance of the surface of substrates such as glass, plastic sheets, and plastic lenses, a technique of forming a hard coat film on the surface of the substrate is known. An organic resin film or an inorganic resin film. In addition, in order to further improve the scratch resistance, resin particles or inorganic particles such as silica are further mixed into the organic resin film or the inorganic film. [0003] In addition, it is known to form an anti-reflection film on the surface of substrates such as glass, plastic sheets, and plastic...
