A photopolymerizable composition for forming a cosmetic coating for nails comprises a continuous phase and a discontinuous phase. The continuous phase comprises (meth)acrylate monomers, crosslinkers, photoinitiators, and optionally (meth)acrylate oligomers and other additives. The discontinuous phase comprises particles such as polymers, inorganic materials or a mixture thereof. The particle sizes of the components of the discontinuous phase mixture are in the range of several microns or tens of microns. This composition has good storage stability, exhibits high viscosity, and has a relatively low exotherm when used. The composition can be shaped readily by a nail technician to form nail coatings and is then exposed to actinic light to form a nail coating. The photopolymerizable composition may be kept in a container such as a tube container, a syringe container, and a foil packet.
