| 发明名称 | Coating composition and coated body | ||
| 摘要 | There is provided a coating composition that can form a coating film excellent in both weather fastness and hydrophilifiability. The coating composition includes: a Si-containing resin; photocatalyst particles; and an aqueous medium, the Si-containing resin and the photocatalyst particles being dispersed in the aqueous medium, wherein the Si-containing resin includes a polysiloxane segment, preferably exhibits at least one spectral peak at a position of 120° C. or more to 180° C. or less in a curve of loss tangent (tan δ) against temperature as measured at a frequency of 1 Hz with a solid viscoelasticity measuring apparatus based on JIS K 7244-4, and has a particle diameter that is not more than 1/15 of the particle diameter of the photocatalyst particles. | ||

| 主权项 | 1. A coating composition comprising: a Si-containing resin; photocatalyst particles; and an aqueous medium, the Si-containing resin and the photocatalyst particles being dispersed in the aqueous medium, wherein the Si-containing resin comprises a polysiloxane segment and the Si-containing resin has a particle diameter that is not more than 1/15 of the particle diameter of the photocatalyst particles, wherein the polysiloxane segment is a trifunctional polysiloxane segment and the Si-containing resin exhibits at least one spectral peak at a position of 120° C. or more to 180° C. or less in a change curve of loss tangent (tan δ) against temperature as measured at a frequency of 1 Hz with a solid viscoelasticity measuring apparatus based on JIS K 7244-4. | ||
