Description

The present invention relates to a liquid composition for making a surface layer containing an ultraviolet curable resin or a volatile dry paint into a glossy mirror surface. In particular, the present invention relates to mirror nails and aurora nails that make the nails of hands and toenails look like a glossy mirror, and mirror coating or aurora coating that makes the surface of accessories look like a glossy mirror.

Nail design that coats the surface of the nails of the hands and toenails is also called nail art, and is widely enjoyed for the purpose of decorating the nails, and various decoration techniques have been developed. And nail polish was used for the nail design. Further, in recent years, cases where curable gel nails using UV light or LED light are used are increasing, and ultraviolet curable resins are used for these gel nails (for example, Patent Documents 1 and 2).

As a kind of nail design, mirror nails that have a metallic design like a shining mirror and aurora nails that become worm-colored by changing the selection of the base color are known.

Generally, the procedure for producing mirror nails and aurora nails is as follows: (1) a base gel is applied to the nails and cured, and (2) a desired color gel is applied once or twice or more on the nails if necessary. Apply and cure, (3) apply clear gel on it and cure, (4) put mirror nail powder (also called mirror powder) on the entire surface of the cured surface, and use an eyeshadow tip. It is done by rubbing it with pressure to make the entire surface look like a glossy mirror, and (5) applying top gel on it and curing it.

Here, the mirror powder used in mirror nails and aurora nails is a light fine powder, and skillful skill is required to apply the required amount to the edge of the nail, which is the application surface, and the mirror powder is used to some extent on the nail. However, the amount of mirror powder that falls off tends to increase by placing a large amount of mirror powder in order to obtain a beautiful finish. However, even if the mirror powder adheres to clothes or hands, it is difficult to remove it easily. Therefore, in order to prevent the mirror powder that has fallen off on the desk or floor from adhering to the surroundings of clothes or hands as much as possible. Care must be taken in its handling.

In addition, since it is difficult to finely adjust the position of the mirror powder placed on the nail, the glossy mirror surface is the entire nail, but for example, a part of the nail is made into a beautiful glossy mirror surface. , It was difficult to make a part having a smaller area than the entire surface of the nail into a glossy mirror surface with a desired design.

On the other hand, artificial nails are known as nail accessories, and it is also known to apply mirror nails and aurora nails to the surface of these artificial nails by the above procedure, but when mirror powder is used, it is known. As described above, care must be taken in handling 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 that an ultraviolet curable resin (also referred to as UV resin) is used as a base material for accessories such as brooches and accessories (Patent Document 3).

Here, since the UV resin is colorless and transparent, when coloring the UV resin, a liquid or powder colorant for the resin, a powder pigment, an acrylic paint, or the like is mixed with the UV resin liquid. Therefore, a method of coloring the UV resin liquid itself is known. Then, after the UV resin liquid is solidified, it is also attempted to apply a desired coloring or gel nail using a volatile dry type paint such as nail polish.

However, when the surface of accessories is made to have a glossy mirror surface such as mirror nails and aurora nails, no method is known other than using mirror powder, and when mirror powder is used, it adheres as described above. Care must be taken in handling in terms of sex, and it was also difficult to make a glossy mirror surface, especially for accessories with a smaller area than the nails.

As described above, the UV paint applied to the surface of nails or accessories includes a base coat on which only clear gel is applied, or a base coat on which a color coat is applied and then clear gel is applied. Examples include those that have been applied.
The method of applying the UV paint to the surface of nails or accessories, and the method of curing the UV paint with UV light or LED light are known in the fields where UV paint is used on a daily basis, for example, in the nail industry and the accessory industry. Any method may be used, but there is no particular limitation.

Examples of the method for applying the liquid composition of the present invention to the surface of the UV paint cured as described above include brushes and brushes, but are not particularly limited.
In this case, since the coating can be applied to a desired location, waste of the effect pigment is reduced and economic efficiency is improved as compared with the conventional method of sprinkling mirror powder.
In addition, it is possible to design the coated surface with a brush, brush, etc., and it is possible to handle advanced design techniques.
Further, a sticker having a gap having a desired design is attached to the surface of the nail in advance, the liquid composition of the present invention is applied on the sticker, and then the sticker is peeled off to obtain a desired shape. A glossy design can be provided on the surface of nails and accessories.

The liquid composition applied as described above is allowed to stand to dry the aqueous medium. The state of standing still cannot be unconditionally limited by the composition of the aqueous medium, but for example, when the aqueous medium contains ethanol, it can be dried by standing relatively quickly at room temperature.
The degree of drying is not particularly limited as long as it can be confirmed that the coated surface is no longer liquid.

Next, the method of rubbing the dry surface of the liquid composition may be any material as long as it is made of a flexible material that does not easily damage the dry surface when pressed, and is not particularly limited, but for example, eye shadow. Chips, sponges, silicon sticks and the like can be used.
By performing the above rubbing, the effect pigment that is on the dry surface and is not aligned is rubbed against the surface layer of the cured UV paint, so that the direction of the effect pigment is aligned and the light reflection angle is made uniform. The surface of the nail becomes glossy mirror-like.

In order to maintain the glossy mirror-like state obtained as described above, a top coat is applied from above.

The method using volatile dry paint is
A process of applying a volatile dry paint to the surface of nails or accessories and drying it to form a surface layer of the volatile dry paint.
