Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a nail varnish containing nitrification cotton, a plasticizer, and a solvent, in which a silicone resin and an acrylic resin and / or a sulfonamide resin are blended,
The present invention relates to a nail enamel that has excellent color development, luster and dryness and has a long-lasting makeup.

[0002]

2. Description of the Related Art Conventionally, the qualities required of nail enamel include the drying property of a coating film, luster, color development, and makeup retention. As a technique for improving the gloss of the coating film, it is known to blend a sulfonamide resin or an alkyd resin. Known techniques for improving the color development of the coating film include improving the dispersibility by chipping the pigment and blending barium sulfate. As a technique for improving makeup lasting, a sulfonamide-based resin, sucrose benzoate or the like may be blended (Japanese Patent Laid-Open No. 60-21560).
7) etc. are known. Recently, attention has been focused on the quick-drying property of a coating film, and many quick-drying nail polishes and quick-drying sprays have been released.

[0003]

[Problems to be Solved by the Invention] A quick-drying spray is
The volatile solvent has an effect of promoting solvent separation from the resin to produce quick drying, but the effect is not sufficient, and it is necessary to spray this after applying nail enamel. There was a drawback that the usability was complicated.
Also, for quick-drying nail enamel, in order to exert its effect, the solvent composition is changed, the resin concentration is lowered, and a silicone derivative or the like is blended (JP-A-2-25411). However, a sufficient effect cannot be obtained only by adjusting the solvent composition, and there is a drawback that the stability of the system is impaired. Further, when the resin concentration is lowered, the coating film becomes thin, and the makeup lasts poorly. When a silicone derivative is mixed in a nail varnish, the silicone derivative has poor compatibility with other resins and poor adhesion to the nail, so the coating film may partly peel off over time, or from the tip of the nail. It had the drawback that the makeup lasted poorly, such as being worn away. As a method of improving the above-mentioned drawbacks, various resin formulations have been studied, but the sufficient effect has not been obtained yet. That is, it has been desired that the coating film of the nail enamel is excellent in dryness and that the makeup retention is further improved.

[0004]

In view of the above situation, the inventors of the present invention have conducted earnest research, and as a result, in a nail varnish containing nitrification cotton, a plasticizer, and a solvent, a silicone resin and an acrylic resin were used. It has been found that, by blending with and / or a sulfonamide resin, the compatibility of the silicone derivative is improved, the makeup retention of the coating film is improved, and a nail enamel excellent in drying property, color development and luster is obtained. The present invention has been completed. That is, in the nail enamel containing nitrified cotton, a plasticizer, and a solvent, the present invention is a nail enamel characterized by blending a silicone resin and an acrylic resin and / or a sulfonamide resin.

The silicone resin used in the present invention is
The thing normally used for cosmetics can be used.

Preferably, an acrylic-silicone graft copolymer is used. Examples of the acrylic-silicone-based graft copolymer include those described in JP-A-2-25411 and the like. For example, a radical polymerizable group at one end of the molecular chain represented by the general formula (1) is used. It is synthesized by radically copolymerizing the dimethylpolysiloxane compound (A) and the radically polymerizable monomer (B) mainly containing acrylate and / or methacrylate.
