Description

The present invention relates to a liquid composition for making a surface layer containing an ultraviolet curable resin or a volatile drying type coating a glossy mirror surface. In particular, the present invention relates to a mirror nail coating or an aurora nail coating for making the nails of hands or feet glossy mirror-like, and a mirror coating or aurora coating for making the surfaces of accessories a glossy mirror surface.

Nail design, which coats the surface of the nails of hands and feet, is also called nail art, and is widely enjoyed for the purpose of decorating nails, and various decorative techniques have been developed. And nail polish was used for nail design. Further, in recent years, a case where a curable gel nail by UV light or LED light is used is increasing, and an ultraviolet curable resin is used for this gel nail (for example, Patent Documents 1 and 2).

And as a kind of nail design, a mirror nail that becomes a metallic design like a shining mirror and an aurora nail that becomes iridescent by changing the selection of the base color are known.

In general, the procedure for making a mirror nail or an aurora nail is (1) applying a base gel to the nail and curing it, and (2) applying a desired color gel once or twice or more if necessary. Apply and cure, (3) Apply clear gel on it and cure, (4) Put the mirror nail powder (also called mirror powder) on the entire cured surface, and use the eye shadow chip The entire surface is made into a glossy mirror by rubbing it under pressure, and (5) top gel is applied on top of it to cure it.

Here, the mirror powder used in mirror nails and aurora nails is a fine powder that requires a skilled technique to put the required amount up to the edge of the nail, which is the application surface. The amount of mirror powder that falls off tends to increase by adding a large amount of mirror powder to obtain a clean finish. However, it is difficult to remove the mirror powder easily when it adheres to your hands as well as clothes, so in order to prevent the mirror powder that has fallen off the desk or floor from sticking to your clothes or hands as much as possible, Care must be taken in its handling.

Also, since it is difficult to finely adjust the position of the mirror powder to be placed on the nail, the glossy mirror surface is the entire nail, but for example, a part of the nail has a clean glossy mirror surface. However, it was difficult to make a portion having a smaller area than the entire surface of the nail into a glossy mirror surface with a desired design.

On the other hand, as a nail accessory, an artificial nail is known, and it is also known to apply a mirror nail or an aurora nail to the surface of the artificial nail by the procedure described above, but when using a mirror powder, However, as described above, it is necessary to handle with care in terms of adhesiveness, and it is also difficult to make a glossy mirror surface with a desired design in a smaller area.

Further, it is known to use an ultraviolet curable resin (also referred to as a UV resin) as a base material for accessories such as broaches and accessories (Patent Document 3).

Here, since the UV resin is colorless and transparent, when coloring, the UV resin liquid is mixed with a liquid or powdery resin colorant, a powdery pigment, an acrylic paint, or the like. Therefore, a method of coloring the UV resin liquid itself is known. It has also been attempted to solidify the UV resin solution and then apply a desired color using a volatile dry coating such as nail polish or apply gel nail.

However, when making the surface of accessories a glossy mirror surface such as mirror nail or aurora nail, there is no known method other than using mirror powder, and when using mirror powder, as described above, It is necessary to handle it with care in terms of performance, and it is difficult to make it a glossy mirror surface, especially for accessories with a smaller area than the nail.
