Abstract

PURPOSE: An ultramarine blue composition having improved chemical, weather, and heat resistance, etc., obtained by coating the surfaces of ultramarine blue particles with fine amorphous silica deposited from silica sol.
CONSTITUTION: A) An alkali silicate is reacted with B) an organic compound, preferably an organic acid, capable of forming silica sol by reacting with A) in an aqueous slurry of ultramarine blue at preferably not lower than 60°c in the pH range of 9W11 to give silica sol. The surfaces of the ultramarine blue particles are coated with fine amorphous silica to give the desired composition.
