The plurality of types of the colloidal particles include at least first colloidal particles and second colloidal particles, which are different in average particle size from each other. Then, the plurality of types of the colloidal particles form a regular array in a matrix. A multi-colloidal structure includes a plurality of the colloidal structures. A method for producing a colloidal structure includes: a dispersion liquid preparation step of preparing a colloidal dispersion liquid by dispersing a plurality of types of colloidal particles together with a monomer; a coating film generation step of coating the colloidal dispersion liquid on a substrate, and generating a coating film; and a polymerization step of polymerizing the monomer in the coating film.

摘要： Quinacridone pigments that are surface-functionalized with glycidyl methacrylate, maleic anhydride, or 4-methacryloxyethyl trimellitic anhydride to create a functionalized pigment. The functional groups are then activated to bond hydrophobic polymers, thereby coating the pigment with the hydrophobic polymers. The quinacridone pigments can be used for a variety of applications. They are well-suited for use in electro-optic materials, such as electrophoretic media for use in electrophoretic displays.

摘要： Curable, coatable compositions include silane surface-treated inorganic nanoparticles with a high refractive index, and a curable reaction mixture. The curable reaction mixture includes a first (meth)acrylate monomer comprising a high refractive index (meth)acrylate monomer with a refractive index of 1.6 or higher, a second (meth)acrylate monomer comprising a lower refractive index (meth)acrylate monomer with a refractive index of less than 1.6, and at least one initiator. Cured optical coatings prepared from the compositions are optically clear, having a visible light transmission of at least 88% and a haze of 5% or less, and have a refractive index of at least 1.78, and are capable of passing a 10 millimeter mandrel flexibility test.
