Silicon oxide-coated oxide composition for coating in which weather resistance is required, and method of producing composition for coating

A composition for coating, which is used by blending the composition for coating to a paint constituting a coated body in which weather resistance is required,

• wherein the composition for coating comprises silicon oxide-coated oxide particles which comprise oxide particles and silicon oxide wherein at least a part of the surface of the oxide particles is coated with the silicon oxide,
• wherein the silicon oxide is amorphous, and
• wherein the silicon oxide-coated oxide particles are constituted so that reflectivity for the light of 380 to 780 nm is higher than that of oxide particles which surface is not coated with silicon oxide.

A method of producing a composition for coating comprising oxide particles, which is used by blending the composition for coating to a paint constituting a coated body in which weather resistance is required,

• wherein color characteristics of the oxide particles are controlled by producing the oxide particles by selecting presence or absence of amorphous silicon oxide covering at least a part of the surface of the oxide particles, and presence or absence of an acetyl group as a functional group contained in the silicon oxide-coated oxide particles.
