Problems solved by technology

However, in the process of curing, the artificial nail is deformed due to curing shrinkage, so there is a problem that the manufacturing accuracy is lowered, and a high fit feeling cannot be obtained when the artificial nail is attached.

[0360]

[0361] The components shown in the following Tables 1 to 4 were mixed to obtain a photocurable composition.

[0362]

[0363] Using the obtained photocurable composition, the following measurement and evaluation were performed. The results are shown in Tables 1-4.

[0364] (viscosity of photocurable composition)

[0365] The viscosity of the photocurable composition was measured with an E-type viscometer at 25° C. and 50 rpm.

[0366] (bending strength and flexural modulus of optical modeling objects)

[0367] The obtained photocurable composition was shaped into a size of 80 mm×10 mm×thickness 4 mm using a 3D printer (FormLab Form 2) to obtain a shaped object. For the resulting shape, 5J / cm 2 Under certain conditions, ultraviolet light with a wavelength of 365 nm was irradiated to make it photocured, thereby obtaining a photomodeling object.

[0368] The flexural strength and flexural modulus of the test piece were measured according to ISO178 (or JIS K 7171...

Description

technical field [0001] The present invention relates to a photocurable composition, artificial nails, a method for generating styling data for artificial nails, a method for manufacturing artificial nails, and a system for manufacturing artificial nails. Background technique [0002] Nail art, such as nail care, manicure, and pedicure, is popularized for caring, making up, and decorating the nails of hands and feet. In recent years, nail arts such as nail chips, sculptures, and tip overlays using decorated false nails (ie, artificial nails) have become more and more popular. [0003] The so-called nail art is the makeup or decoration implemented on the nails of hands and feet. A shop that performs nail art is called a nail salon, and its technicians are called manicurists. There are a variety of nail art supplies on the market, and there are many women who are doing nail art on their own as well as professionals. [0004] In the 19th century, lacquer paints for automobile...
