Abstract:
(EN) [Problem] The present invention addresses the problem of providing: a coating liquid for forming a visible light scattering coating film, which is suitable for industrial production of a visible light scattering coating film; and a visible light scattering coating film which is based on this coating liquid. [Solution] A coating liquid for forming a visible light scattering coating film, which contains: visible light scattering particles; a precursor compound of a visible light-transmitting film-forming oxide network polymer medium which serves as a dispersion medium for the visible light scattering particles; and a solvent. This coating liquid for forming a visible light scattering coating film is configured such that: a hydrophilic polymer having a weight average molecular weight of more than 500,000 but 3,000,000 or less is additionally contained therein; and the ratio of the hydrophilic polymer (B) to the mass (A) of the visible light scattering particles, namely the mass ratio B/A is 0.02-25.
(FR) La présente invention aborde le problème consistant à fournir : un liquide de revêtement permettant de former un film de revêtement de diffusion de lumière visible, qui est approprié pour une production industrielle d'un film de revêtement de diffusion de lumière visible ; et un film de revêtement de diffusion de lumière visible qui est basé sur ce liquide de revêtement. La solution selon l'invention porte sur un liquide de revêtement permettant de former un film de revêtement de diffusion de lumière visible, qui contient : des particules de diffusion de lumière visible ; un composé précurseur d'un milieu polymère de réseau d'oxyde formant un film transmettant la lumière visible qui sert de milieu de dispersion pour les particules de diffusion de lumière visible ; et un solvant. Ce liquide de revêtement permettant de former un film de revêtement de diffusion de lumière visible est conçu de sorte que : un polymère hydrophile ayant une masse moléculaire moyenne en poids supérieure à 500 000 mais inférieure ou égale à 3 000 000 est en outre présent en son sein ; et le rapport du polymère hydrophile (B) à la masse (A) des particules de diffusion de lumière visible, à savoir le rapport massique B/A, est de 0,02 à 25.
