To maximize the critical angle, θ c , and the reflectance, R , in total internal reflection reflective image displays, the difference in the refractive indices between the surface of the transparent front sheet and the liquid medium comprising of electrophoretically mobile particles must be maximized. High index optical glasses may be used to fabricate the front sheet but are costly and difficult to manufacture with fine structural features. Polymers may be used to fabricate the transparent front sheet as they are cheaper and simpler to process into desired structures but typically have low indices of refraction. Polymers comprising of dispersed high refractive index particles may be used to increase the refractive index of the transparent front sheet. The polymers may be formed from UV-curable liquid monomers.

[Problem] To provide a molded article that maintains the visual effect obtained by being formed from a clear and colorless or clear and colored material, and avoids hazards such as personal injury and environmental accidents. [Solution] Molded articles (42, 43) are formed from a clear and colorless or clear and colored material with the peripheries thereof having uneven contours, and are integrally molded in an undetachable manner. The molded article (42) is formed from a smooth, irregular polyhedron, and the molded article (43) is formed from a plurality of recesses (44) that are formed by firing. The molded articles (42, 43) refract and reflect incident light in various directions such that said light is radiated outward from the molded articles and visible to an observer. In the case of the molded article (43), sections where the recesses (44) are in shadow accentuate a housed object (45) so as to be visible to an observer. Accordingly, hazards caused by focused light, such as personal injury including burns and environmental accidents including fires, are avoided by suppressing the transmission of light from the irregular polyhedron and the recesses (44), while scattering and reflecting incident light so as to maintain the visual effect of a brightly sparkling surface.

摘要:
A coating composition includes a first polymer and a second polymer that are incompatible and non-reactive with one another. The absolute value of the difference between the refractive index of the first polymer and the refractive index of the second polymer is about 0 to about 0.01. The first polymer and the second polymer are soluble in a carrier liquid that is a good solvent for the first polymer and a poor solvent for the second polymer. The carrier liquid is removed from the coating layer to spinodally decompose the mixture of the first polymer and the second polymer in an amount sufficient to form a substantially continuous first phase with a predominant amount of the first polymer and a substantially discontinuous second phase with a predominant amount the second polymer. At least 70% of the second phase includes droplets with an aspect ratio, when viewed in the plane of the surface of the substrate, of less than about 3.
