Abstract
Description
本発明は溶剤系美爪料に関し、さらに詳しくは、爪に対する閉塞感が少なく、使用性、化粧持ちに優れ、しかも経時安定性にも優れ、さらに塗膜の平滑性が高く、ツヤに優れた溶剤系美爪料に関するものである。 The present invention relates to a solvent-based beauty nail material, and more specifically, there is little occlusion to the nail, excellent usability and makeup retention, excellent stability over time, high smoothness of the coating film, and excellent gloss. The present invention relates to a solvent-based beauty nail material.
これまで溶剤系美爪料において、皮膜強度向上、皮膜のツヤ向上、化粧持ち向上等の目的でニトロセルロースをはじめ、アルキッド樹脂やスルホンアミド樹脂、アクリル酸系樹脂、シリコーン系樹脂等が皮膜形成剤として用いられてきた。なかでもシリコーン系の樹脂は耐水性を高め、塗膜表面を平滑にすることでツヤの向上や化粧持ちを向上させる効果が得られるため、検討されてきた。また、塗膜の強度や化粧持ちを向上させるにつれ、塗膜による爪の圧迫感も増大する傾向があるため、化粧持ちに優れながらも、爪の圧迫感を減少させる研究がなされてきた。例えば、特定のシリコーン樹脂とニトロセルロースを組み合わせた技術（例えば特許文献1参照）やニトロセルロースと特定の非水系ポリマーディスパージョンを組み合わせた技術（例えば特許文献２参照）が挙げられる。
また、爪の圧迫感を減少させるだけではなく、酸素透過性を更に向上させた技術としてニトロセルロースにかえて、カルボキシル基を導入したシリコーン系樹脂を用いることが検討されている。（例えば特許文献３参照）
So far, in solvent-based nail polishes, nitrocellulose, alkyd resin, sulfonamide resin, acrylic acid resin, silicone resin, etc. are used as film forming agents for the purpose of improving film strength, improving film gloss, and improving makeup durability. Has been used. In particular, silicone resins have been studied because they can improve water resistance and smoothen the surface of the coating film, thereby improving gloss and improving the durability of the makeup. In addition, as the strength of the coating film and the longevity of the makeup are improved, there is a tendency that the feeling of pressure on the nail by the coating film tends to increase. For example, the technique (for example, refer patent document 1) which combined specific silicone resin and nitrocellulose, and the technique (for example, refer patent document 2) which combined nitrocellulose and the specific non-aqueous polymer dispersion are mentioned.
In addition to reducing the feeling of pressure on the nails, as a technique for further improving oxygen permeability, the use of a silicone resin into which a carboxyl group is introduced in place of nitrocellulose has been studied. (For example, see Patent Document 3)
しかしながら、特定のシリコーン樹脂や非水系ポリマーディスパージョンとニトロセルロースを組み合わせた溶剤系美爪料では、爪の圧迫感は減少するものの、まだ、期待値には至らず、樹脂同士の相溶性が悪く、使用性が悪化する場合があった。また、酸素透過性を向上させた技術は、系の粘度調整が難しく、その塗膜強度は、従来の樹脂を使用したもの程は得られなかった。
このように、これまで酸素透過性があり、他の皮膜形成剤との相溶性に優れた皮膜形成剤の開発はされてこなかった。
そこで、爪に対する閉塞感（圧迫感）が少なく、使用性、経時安定性および化粧持ちに優れた溶剤系美爪料が望まれていた。さらに、爪および指先を美しく見せる為、塗膜の平滑性が高く、ツヤに優れる溶剤系美爪料が望まれていた。
However, with solvent-based nail polish that combines nitrocellulose with a specific silicone resin or non-aqueous polymer dispersion, the feeling of pressure on the nail is reduced, but it still does not reach the expected value and the compatibility between the resins is poor. In some cases, usability deteriorated. In addition, the technology that improves oxygen permeability makes it difficult to adjust the viscosity of the system, and the coating strength is not as high as that using conventional resins.
Thus, a film forming agent having oxygen permeability and excellent compatibility with other film forming agents has not been developed so far.
Therefore, there has been a demand for a solvent-based beauty nail material that has little occlusion (compression) to the nail, and is excellent in usability, stability over time, and long-lasting makeup. Furthermore, in order to make nails and fingertips look beautiful, there has been a demand for a solvent-based beautiful nail material that has a smooth coating film and is excellent in gloss.
かかる事情に鑑み、本発明者らは鋭意検討した結果、特定の構造を持つシロキサン基含有（メタ）アクリル酸系共重合体が、溶剤中で他の皮膜形成との相溶性が良く、爪に対する閉塞感が少なく、使用性、化粧持ちに優れ、また有機溶剤が経時により分離する離漿がなく、粉体配合時は粉体の沈降がなく分散性が向上する等の経時安定性に優れ、さらに塗膜の平滑性が高く、ツヤに優れるることを見出し、本発明を完成させた。 In view of such circumstances, as a result of intensive studies, the present inventors have found that a siloxane group-containing (meth) acrylic acid-based copolymer having a specific structure has good compatibility with other film formations in a solvent, and is suitable for nails. There is little feeling of blockage, it is excellent in usability and cosmetic durability, there is no separation that the organic solvent separates over time, and it has excellent temporal stability such as no sedimentation of powder and improved dispersibility when blended with powder, Furthermore, the present inventors have found that the coating film has high smoothness and excellent gloss, and thus completed the present invention.

表１に示す評価結果より、本発明は爪に対する閉塞感のなさ、使用性、化粧持ち、経時安定性、塗膜のツヤの全ての項目において比較例より優れたものが得られた。比較例１のモノマーにメタクリル酸を含有しない共重合体を配合した場合では特に化粧持ちが劣り、他の皮膜形成剤との相溶性が良好ではなかった。成分（Ａ）の代わりにトリメチルシロキシケイ酸を配合した比較例２では爪に対する閉塞感、化粧持ち、塗膜のツヤの項目が劣り、比較例３の成分（Ａ）を配合しない場合では酸素透過性を有する樹脂を配合していないため、爪に対する閉塞感が著しく欠け、塗膜のツヤに劣るものであった。成分（Ｂ）の皮膜形成剤を含有しない比較例４は、系の粘度が得られず、皮膜が弱いため、使用性、化粧持ち、粉体の沈降の項目で良いものは得られなかった。 From the evaluation results shown in Table 1, the present invention was superior to the comparative example in all the items of no occlusion to nails, usability, makeup retention, stability over time, and gloss of the coating film. In the case where a copolymer containing no methacrylic acid was blended with the monomer of Comparative Example 1, the cosmetic durability was particularly poor and the compatibility with other film forming agents was not good. In Comparative Example 2 in which trimethylsiloxysilicic acid was blended instead of component (A), the items of occlusion to the nails, makeup lasting, and gloss of the coating film were inferior. Since the resin having the property is not blended, the clogging feeling with respect to the nail is remarkably lacking and the gloss of the coating film is inferior. In Comparative Example 4 which does not contain the film forming agent of the component (B), the viscosity of the system was not obtained, and the film was weak.

(Smoothness of coating film)
About the smoothness of the coating film, each sample was developed on a glass plate with an applicator having a film thickness of 16 mil (about 0.4 mm) and then dried in a thermostatic bath at 30 ° C. for 24 hours. The dried coating film was held over the light, the light was seen through the film, and the smoothness and gloss of the coating film were visually observed and judged according to the following criteria.
(Coating state): (Judgment)

There are many irregularities on the surface and it is inferior to the gloss: ×
表２に示す評価結果より、本発明は爪に対する閉塞感のなさ、化粧持ち、塗膜の平滑性の全ての項目において比較例より優れたものが得られた。
一方、成分（Ａ）の代わりにトリメチルシロキシケイ酸を配合した比較例５では、爪に対する閉塞感、化粧持ち、塗膜の平滑性の全て項目が劣る結果となった。比較例６の成分（Ａ）を配合しない場合では、爪に対する閉塞感が著しく欠けるが、化粧持ち、塗膜の平滑性は得られた。成分（Ｂ）の皮膜形成剤を含有しない比較例７は、皮膜が脆く、触ると割れてしまった。比較例８は、比較例６のニトロセルロースの配合量を増加させたが、結果は変わらなかった。比較例９は、比較例７の成分（Ａ）の配合量を増加させたが、平滑性は向上したものの、皮膜が脆く、触ると割れてしまった。
From the evaluation results shown in Table 2, the present invention was superior to the comparative example in all items of no occlusion to the nails, makeup holding, and smoothness of the coating film.
On the other hand, in the comparative example 5 which mix | blended trimethylsiloxysilicic acid instead of the component (A), the result of being inferior in all the items of the blockage feeling with respect to a nail | claw, a cosmetics holding | maintenance, and the smoothness of a coating film. In the case where the component (A) of Comparative Example 6 was not blended, the feeling of blockage with respect to the nail was remarkably lost, but the makeup lasting and smoothness of the coating film were obtained. In Comparative Example 7 not containing the component (B) film-forming agent, the film was brittle and cracked when touched. In Comparative Example 8, the amount of nitrocellulose in Comparative Example 6 was increased, but the results were not changed. In Comparative Example 9, the amount of component (A) in Comparative Example 7 was increased, but although the smoothness was improved, the film was brittle and cracked when touched.
