Abstract
The present invention provides an acrylic resin composition containing a polycrystal of colloidal particles of silicon oxide in an acrylic resin that is formed by curing an acrylic monomer liquid at room temperature and/or an acrylic oligomer liquid at room temperature, wherein a mean distance between the colloidal particles in the polycrystal is 140 to 330 nm. The size of the single crystal that constitutes the polycrystal can be controlled by adjusting the content of silicon oxide and/or the additive amount of impurities. An architectural material, a fashion accessory, and an optical material are provided that are formed by using the acrylic resin composition.
