Kind Code:

A1

Abstract:

[Problem] To provide: a decorative aqueous composition that contains particles of opal-like colloidal crystals uniformly and stably dispersed in an aqueous dispersion medium, and exhibits a structural color due to light interference; and a method for producing the decorative aqueous composition. [Solution] The present invention provides a decorative aqueous composition that contains particles of opal-like colloidal crystals dispersed in an aqueous dispersion medium in which a polymer is dissolved, wherein the particles of opal-like colloidal crystals are composed of hydrophilic colloid particles having an average particle size in the range of 10-1000 nm and having a particle size variation coefficient of 20% or less. Thus, this decorative aqueous composition contains opal-like colloidal crystals uniformly and stably dispersed in an aqueous dispersion medium, and exhibits a structural color due to light interference. As a result, the decorative aqueous composition can be suitably used for lotions and the like.
