There is disclosed an optically clear shear thickening fluid and a protection assembly comprising the optically clear shear thickening fluid. It further relates to uses of the optically clear shear thickening fluid in electronic devices, particularly in optical display devices. The optically clear shear thickening fluid includes: (a) a solid nanoparticle having an average particle size equal to or less than 100 nm; (b) at least one polymer; and (c) a liquid medium. The at least one polymer is substantially soluble in the liquid medium.

A color coating solution is produced by dispersing a nano-color pigment and a metallic gloss pigment into a polymer resin, and the solution is coated and molded on a cover layer having a color similar to that of the color coating solution. Since the pigment composition is different between the cover layer and the color coating layer, internal shieldability is improved. As a result, a dark color or uneven surface of the core, mantle, or cover is not exposed, so that a surface defect rate can be reduced. Since both the nano-color pigment and the metallic gloss pigment are used in the color coating layer, the metallic gloss and the color are exhibited in a single layer. Therefore, it is possible to provide natural metallic gloss without a strange texture feeling.

There is provided a paint formulation comprising a composite pigment, said composite pigment being selected from the group consisting of metal oxide/silica, metal oxide/silicate, metal oxide/alumina, metal oxide/metal oxide and metal oxide/zirconia, wherein the size and amount of said composite pigment are selected to increase the opacity of said paint formulation.
