  • DECORATIVE AQUEOUS COMPOSITION AND METHOD FOR PRODUCING SAME
    Publication number: 20200405590
    Abstract: [Object] To provide a decorative aqueous composition that includes particles formed from opal-type colloidal crystals uniformly and stably dispersed in an aqueous dispersion medium, and exhibits a structural color due to interference of light, and to provide a method for producing the decorative aqueous composition. [Solution] The decorative aqueous composition of the present invention contains particles of opal-type colloidal crystals dispersed in an aqueous dispersion medium in which a polymer is dissolved. The particles of the opal-type colloidal crystals are made from hydrophilic colloidal particles having an average particle diameter ranging from 10 nm to 1000 nm with a variation coefficient of the particle diameter being within 20%. Therefore, the decorative aqueous composition of the present invention contains opal-type colloidal crystals uniformly and stably dispersed in an aqueous dispersion medium, and exhibits a structural color due to interference of light.
