Photocurable resin composition for nail or artificial nail, cured product, and method for coating nail or artificial nail
A photocurable resin composition for a nail or an artificial nail can form a cured product that has excellent transparency and gloss while having hardness required for coating a nail or an artificial nail. The photocurable resin composition for a nail or an artificial nail contains components (A) to (D): component (A): a urethane (meth)acrylate oligomer, component (B): a compound having three or more (meth)acryloyl functional groups (excluding the component (A)), component (C): a compound having a molecular weight of 200 or less and having a hydroxyl group and a methacryloyl group (excluding the components (A) and (B)), and component (D): a photoinitiator.
1 . A photocurable resin composition for a nail or an artificial nail, comprising components (A) to (D) below:
component (A): a urethane (meth)acrylate oligomer,
component (B): trimethylolpropane tri (meth)acrylate,
component (C): at least one selected from the group consisting of 2-hydroxypropyl methacrylate and 2-hydroxybutyl methacrylate, and
component (D): a photoinitiator,
wherein the composition comprises 40 to 60 parts by mass of the component (B), 15 to 30 parts by mass of the component (C), and 3 to 9 parts by mass of the component (D), relative to 100 parts by mass of the component (A), and
a yellowness of a cured product of the photocurable resin composition for a nail or an artificial nail is 1.00 or less.
2 . The photocurable resin composition for a nail or an artificial nail according to claim 1 , wherein the component (A) comprises a urethane (meth)acrylate oligomer having a polyether skeleton.
3 . The photocurable resin composition for a nail or an artificial nail according to claim 1 , wherein the component (D) is an acylphosphine oxide-based photoinitiator and/or an alkylphenone-based photoinitiator.
4 . The photocurable resin composition for a nail or an artificial nail according to claim 1 , wherein a glossiness at 60° of the cured product of the photocurable resin composition for the nail or the artificial nail is 80 or more.
5 . The photocurable resin composition for a nail or an artificial nail according to claim 1 , used for a top coat.
6 . A cured product of the photocurable resin composition for a nail or an artificial nail set forth in claim 1 .
7 . A method for coating a nail or an artificial nail, comprising: applying the photocurable resin composition for a nail or an artificial nail set forth in claim 1 on a nail or an artificial nail to form a coating film; and then irradiating the coating film with an active energy ray to cure the coating film.
8 . The photocurable resin composition for a nail or an artificial nail according to claim 1 , wherein glossiness at 20° of the cured product of the photocurable resin composition for the nail or the artificial nail is 70 or more.
