The object of the present invention is to provide a photocurable composition for a topcoat of nails or artificial nails having excellent glossiness and a colorless and transparent outer appearance.

The present invention is related to a photocurable composition for a topcoat of nails or artificial nails including the following components (A) to (C), including 40 to 70% by mass of trimethylol propane trimethacrylate relative to the total amount of the component (B), and satisfying that a cured product thereof with a thickness of 800 μm has transmittance of 10.0% or higher at a wavelength of 400 nm:

component (A); a (meth)acrylic oligomer;

component (B): a trifunctional (meth)acrylic monomer contained at 50 to 100 parts by mass relative to 100 parts by mass of the component (A); and

component (C): a photopolymerization initiator contained at 1 to 20 parts by mass relative to 100 parts by mass of the component (A).

A novel nail polish system is provided. The system includes a non UV-curable base/adhesion coat, a UV- (or UV LED-) curable, water-removable color coat, and a UV- (or UV LED-) curable, highly wear-resistant top coat. The nail color includes water soluble components, making it removable by an aqueous remover once the top coat is breached, allowing water contact. The top coat composition comprises high concentrations of inorganic nanoparticles, thus providing superior scratch protection.
