A photocurable composition for a nail or artificial nail which can form a cured product exhibiting excellent durability (adhesion maintainability to nails). In addition, the present invention provides a photocurable composition for a nail or artificial nail which emits a weaker odor, generates less heat at the time of curing, and can form a cured product exhibiting excellent surface curability. In addition, the present invention provides a photocurable composition for nail or artificial nail which can form a cured product having an excellent shear adhesive force. The photocurable composition for nail or artificial nail according to the present invention contains the following components (A) to (D): component (A): a urethane-modified (meth)acrylic oligomer; component (B): a (meth)acrylamide monomer; component (C): a (meth)acrylic monomer having an acidic group; and component (D): a photoinitiator.

Photocurable composition to be used on fingernails or artificial nails, and method for coating by using same

Using a curable resin composition including the following (A) to (E) configurations, which is excellent in adhesiveness to nails and curing reactivity, and a cured product of which has a certain flexibility, makes it possible to form a coating aiming for protection, decoration, and the like of nails with favorable followability to the nails: (A) 100 parts by mass of a polymer having a urethane structure in molecule and containing acrylic functional groups at both terminals of a molecular chain, (B) 1 to 35 parts by mass of a trifunctional acrylic functional compound of a specific structure, (C) 15 to 75 parts by mass of a compound containing an acrylic functional group having an aliphatic ring structure, (D) 1 to 35 parts by mass of a compound containing an acrylic functional group having an aliphatic chain structure, and (E) 0.5 to 13.5 parts by mass of a photopolymerization initiator.

Curable resin composition

A floor section is formed at the rear of a vehicle body, at one side of the vehicle body. A lifting floor device having a floor body lifted and lowered by a lifting drive device is placed above the vehicle body. The floor body has a cutout at the left side of the floor body, at the rear half thereof. The right side of the floor body is used as a passage for a physically handicapped person. A stairway device is provided between the floor body and the floor section as a passage for an able-bodied person, on the floor body side in the cutout, and the stairway device is pivotable in a vertical plane. A lifting table is placed behind the vehicle body, on the left side thereof so that the lifting table can face the rear end of the passage for a physically handicapped person.
