Title:
LIQUID COMPOSITION FOR FORMING WATER AND OIL REPELLENT BLACK FILM AND PRODUCTION METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2023031896
Kind Code:
A
Abstract:
To provide a liquid composition for forming a film which is black and has water repellency, oil repellency, high strength, and high adhesion.SOLUTION: A liquid composition for forming a water and oil repellent black film is provided, including a titanium oxynitride particle (B) which has a specific surface area diameter of 10 nm-90 nm and with which a fluorine-based functional group component (A) including a perfluoroether structure represented by formula (1) is bound, an autoreactive-type carboxyl group-containing substance or the like (C), and a solvent (D). The liquid composition has a content of the carboxyl group-containing substance or the like (C) of 20 mass%-95 mass% and a sum of the contents of the fluorine-based functional group component (A) and the titanium oxynitride particles (B) of 5 mass%-80 mass% relative to 100 mass% of the whole amount of non-volatile components in the liquid composition. The liquid composition has a mass ratio (A/B) of the fluorine-based functional group component (A) to the titanium oxynitride particles (B) in the range of 0.01-0.50.SELECTED DRAWING: Figure 1
