Abstract
A composition containing photoactive metal oxide particles and capable of reducing generation of an aldehyde compound, etc. caused by photocatalytic action, and a production method for the composition. The composition including photoactive metal oxide particles (A), a dispersant (B), and an organic solvent (C) other than a volatile aldehyde compound, wherein the composition contains a C1-2 alcohol in an amount of 200 ppm or less. The composition, wherein the metal oxide particles (A) contain at least one photoactive metal oxide selected from the group consisting of titanium oxide, tin oxide, and zirconium oxide, and have an average particle diameter of 5 to 60 nm as determined by dynamic light scattering. The photoactive metal oxide particles (A) contain at least one photoactive metal oxide selected from the group consisting of titanium oxide, tin oxide, and zirconium oxide in an amount of 50% by mole or more in the entire metal oxides.
