Abstract

Provided are a clear coating composition which is used for top coats, the composition containing a crosslinking agent and a functional group-containing (meth)acrylate polymer formed by polymerization of a monomer component that includes an aromatic ring-containing (meth)acrylate and a functional group-containing monomer. Also provided is a clear coat composition which is used for top coats, the composition containing a crosslinking agent and a functional group-containing (meth)acrylate polymer formed by polymerization of a monomer component that includes a functional group-containing monomer and a fluorine atom-containing monomer. This clear coat composition has low colorability, has a high refractive index without the use of a filler, provides excellent glossy even when a filler is used, and can be applied to a thick film.
