PROBLEM TO BE SOLVED: To provide photocatalytic particles and a photocatalytic powder exhibiting sufficient photocatalytic properties when irradiated with light from a practical light source of low quantity of light, such as a fluorescent lamp; a material containing the particles or powder, such as an organic polymer composition, a slurry and a coating agent; and a product having a surface exhibiting photocatalytic property and a surface exhibiting hydrophilicity. SOLUTION: The organic polymer composition, the slurry, the coating agent, a film exhibiting photocatalytic property and the product having photocatalytic property are obtained by using the photocatalytic particles obtained by causing a polybasic acid salt containing at least one species selected from the group consisting of alkaline earth metals, transition metals, and Al to be present on the surfaces of titanium dioxide fine particles of high activity.

摘要:
PROBLEM TO BE SOLVED: To provide an aqueous solution of a chitosan, capable of forming a chitosan film having excellent waterproof properties without using other chemicals such as a crosslinking agent; and to provide a method for producing the aqueous solution and a method for coating an article. SOLUTION: The aqueous solution of the chitosan containing citric acid contains the chitosan and the citric acid. The amount of the citric acid is ≤1.1 molar times as much as the mols of the amino groups of the chitosan. The method for coating the article comprises coating the aqueous solution of the chitosan on the front surface or the inner surface of the article, and drying the coated solution so that the water content is ≤15 mass%.
