Abstract

A photocurable composition for a nail or artificial nail which exhibits surface curability corresponding to a UV irradiator and LED irradiation and of which the cured product can exhibit both durability to maintain stable adhesive property in everyday life and soak off property, is colorless and transparent, and is not turbid, or a base coat agent containing the same. The photocurable composition for nail or artificial nail can contain a compound having a (meth)acryloyl group, rosin or a rosin derivative, and a photoinitiator.

First claim

1 - 9 . (canceled)

10 . A photocurable composition for a nail or artificial nail comprising:
component (A): a compound having a (meth)acryloyl group; component (B): rosin or a rosin derivative; and component (C): a photoinitiator.

11 . The photocurable composition for a nail or artificial nail according to claim 10 , wherein the component (A) comprises a (meth)acrylate oligomer and a (meth)acrylate monomer or a (meth)acrylamide monomer.

12 . The photocurable composition for a nail or artificial nail according to claim 11 , wherein the (meth)acrylate monomer comprises a (meth)acrylate monomer having an acidic group.

13 . A base coat agent comprising the photocurable composition for a nail or artificial nail according to claim 10 , wherein the base coat agent can be soaked off.

14 . A cured product of the photocurable composition for a nail or artificial nail according to claim 10 .

15 . A method of producing a cured product, the method comprising curing the photocurable composition for a nail or artificial nail according to claim 10 .

16 . A peeling method comprising peeling off the cured product according to claim 14 which is disposed on a substrate from the substrate using warm water or a solvent.

17 . A method of covering a human nail or an artificial nail, the method comprising applying the photocurable composition for nail or artificial nail according to claim 10 on a human nail or an artificial nail to form a coating film and then irradiating the coating film with an energy ray for curing.

18 . A use method comprising covering a human nail or an artificial nail by the covering method according to claim 17 and then peeling off a cured product of a covering layer using warm water or a solvent.
