Description

本考案は靴に関する。   The present invention relates to shoes.

従来から防水機能を有する靴が考案されている。   Conventionally, shoes having a waterproof function have been devised.

特開平8−196305JP-A-8-196305

しかし、従来の防水機能を有する靴は防水機能を優先させるため、防水機能のない通常の靴に比べて装飾が少なく、外観におけるバリエーションに乏しいという問題があった。   However, conventional shoes having a waterproof function give priority to the waterproof function, and therefore, there is a problem that there are few decorations compared to a normal shoe without the waterproof function and there are few variations in appearance.

そこで、上記課題を解決するための手段として本願実用新案に係る靴は、撥水性合成皮革と、雨水に濡れると色彩が変化する色彩変化部とを備え、前記色彩変化部は、前記撥水性合成皮革の表面に塗布され、特定の模様に形成された着色疎水性インク層と、前記着色疎水性インク層を被覆して形成された親水性インク層とからなることを特徴とする。   Therefore, as a means for solving the above problems, a shoe according to the utility model of the present application includes a water-repellent synthetic leather and a color changing portion that changes color when wet with rainwater, and the color changing portion includes the water-repellent synthetic It is characterized by comprising a colored hydrophobic ink layer applied to the surface of leather and formed in a specific pattern, and a hydrophilic ink layer formed by covering the colored hydrophobic ink layer.

撥水性合成皮革は、靴の表面形状を形成するアッパーを構成するものであり、足の爪先部、甲被部、及び踵部の表面を覆うものであることが好ましい。また、撥水性合成皮革は、靴内部への雨水の染み込みを防止する防水機能を果たす。従って、撥水性合成皮革は、ポリウレタン樹脂、ポリエステル樹脂、アクリル樹脂、塩化ビニル樹脂、天然ゴム、ブタジエンゴム、スチレンブタジエンゴム、又はエチレンプロピレンゴムなどの撥水性樹脂によって構成されていることが好ましい。   The water-repellent synthetic leather constitutes an upper that forms the surface shape of a shoe, and preferably covers the surfaces of the toe portion, the upper portion, and the heel portion of the foot. In addition, the water-repellent synthetic leather has a waterproof function for preventing rainwater from penetrating into the shoe. Accordingly, the water-repellent synthetic leather is preferably composed of a water-repellent resin such as polyurethane resin, polyester resin, acrylic resin, vinyl chloride resin, natural rubber, butadiene rubber, styrene butadiene rubber, or ethylene propylene rubber.

着色疎水性インク層は、液体状の着色疎水性インクを撥水性合成皮革表面に塗布されることにより形成されることが好ましく、塗布時に着色疎水性インクを任意の形状に塗布し、乾燥させることにより特定の模様を呈する着色疎水性インク層を形成する。   The colored hydrophobic ink layer is preferably formed by applying a liquid colored hydrophobic ink to the surface of the water-repellent synthetic leather, and the colored hydrophobic ink is applied in an arbitrary shape and dried at the time of application. Thus, a colored hydrophobic ink layer having a specific pattern is formed.

次に着色疎水性インク層が形成された後、親水性インクを前記着色疎水性インク層が被覆されるように塗布して乾燥させる。これにより、着色疎水性インク層を被覆して形成された親水性インク層が形成される。   Next, after a colored hydrophobic ink layer is formed, a hydrophilic ink is applied and dried so as to cover the colored hydrophobic ink layer. Thereby, the hydrophilic ink layer formed by covering the colored hydrophobic ink layer is formed.

親水性インクは、数マイクロメートル程度の微小な樹脂粉体からなるインク組成物であることが好ましく、親水性インクが乾燥することによって前記樹脂粉体同士が三次元網目構造を構成して互いに固着することにより、親水性インク層内部に微細な空隙が多数形成されるものであることが好ましい。   The hydrophilic ink is preferably an ink composition composed of a fine resin powder of about several micrometers, and the resin powder forms a three-dimensional network structure and adheres to each other by drying the hydrophilic ink. By doing so, it is preferable that many fine voids are formed inside the hydrophilic ink layer.

親水性インク層が微細な空隙を多数有していることにより、親水性インク層が乾燥している場合には空隙部分には空気が充填されている。この場合、親水性インク部分と空隙部分との屈折率の差が大きいために親水性インク層の下層にある着色疎水性インク層からの光が散乱し、着色疎水性インク層の色彩を靴の外部から見ることはできない。   Since the hydrophilic ink layer has many fine voids, the void portion is filled with air when the hydrophilic ink layer is dry. In this case, since the difference in refractive index between the hydrophilic ink portion and the void portion is large, light from the colored hydrophobic ink layer under the hydrophilic ink layer is scattered, and the color of the colored hydrophobic ink layer is changed to that of the shoe. It cannot be seen from the outside.

一方、親水性インク層が雨水に濡れると前記空隙に水が染み込む。そのため、親水性インク層の親水性インク部分と空隙部分との屈折率の差が小さくなることによって、光の散乱が抑制される。これにより着色疎水性インク層からの光が親水性インク層を透過し、着色疎水性インク層の色彩を靴の外部から透かして見ることができる。   On the other hand, when the hydrophilic ink layer gets wet with rain water, water penetrates into the gap. Therefore, light scattering is suppressed by reducing the difference in refractive index between the hydrophilic ink portion and the void portion of the hydrophilic ink layer. Thereby, the light from the colored hydrophobic ink layer is transmitted through the hydrophilic ink layer, and the color of the colored hydrophobic ink layer can be seen through from the outside of the shoe.

このような構造により、色彩変化部は、雨水に濡れる前と濡れた後で色彩が変化したように見え、本願発明に係る靴は見た目に楽しい外観を備えることができる。   With such a structure, the color changing portion appears to have changed in color before and after being wet with rainwater, and the shoe according to the present invention can have a visually pleasing appearance.

従って、親水性インクは、雨水に濡れた際に着疎水性インク層の色を透けて見え易くするために、白色若しくは白色に近い明色であることが好ましい。   Therefore, the hydrophilic ink is preferably white or a light color close to white in order to make it visible through the color of the hydrophobic ink layer when wet with rainwater.

なお、着色疎水性インク層は疎水性を有しているため、靴が雨水に濡れた際にも着色疎水性インク層には雨水が染み込まない。そのため、雨水の染み込みによる着色疎水性インク層の屈折率の変化は生じず、着色疎水性インク層自体の色彩の変化を防止することができる。   Since the colored hydrophobic ink layer has hydrophobicity, rainwater does not soak into the colored hydrophobic ink layer even when the shoe is wet with rainwater. Therefore, the refractive index of the colored hydrophobic ink layer does not change due to the infiltration of rainwater, and the color change of the colored hydrophobic ink layer itself can be prevented.

本願考案によれば、あらかじめ形成された特定の模様部分の色彩が雨に濡れることによって異なった色彩に変化するため、通常の靴にはない見た目に楽しい外観を備えた靴を提供することができる。   According to the present invention, since the color of a specific pattern portion formed in advance changes to a different color when it gets wet with rain, it is possible to provide a shoe with a pleasant appearance that is not found in ordinary shoes. .

以下、本願考案に係る実施の形態を、図を参照しながら詳しく説明する。   Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

本願考案に係る靴1は、図1に示すように、ポリウレタン樹脂からなる撥水性合成皮革2の表面に色彩変化部3からなる模様が付されている。   As shown in FIG. 1, a shoe 1 according to the present invention has a pattern made of a color changing portion 3 on the surface of a water-repellent synthetic leather 2 made of polyurethane resin.

色彩変化部3及びその周辺部の断面構造を図2に示す。撥水性合成皮革2は、裏革6の表面に張り合わされて構成されている。そして色彩変化部3は、撥水性合成皮革2の表面上に塗布形成された着色疎水性インク層4及び着色疎水性インク層4を被覆して塗布形成された親水性インク層5とからなる。   FIG. 2 shows a cross-sectional structure of the color changing portion 3 and its peripheral portion. The water-repellent synthetic leather 2 is configured by being bonded to the surface of the back leather 6. The color changing portion 3 includes a colored hydrophobic ink layer 4 formed on the surface of the water-repellent synthetic leather 2 and a hydrophilic ink layer 5 formed by coating the colored hydrophobic ink layer 4.

靴1が乾燥している場合には、図1に示すように色彩変化部3の最表面に形成された親水性インク層5の色彩によってあらわされる第一の模様Aを視認することができる。   When the shoe 1 is dry, the first pattern A represented by the color of the hydrophilic ink layer 5 formed on the outermost surface of the color changing portion 3 can be visually recognized as shown in FIG.

靴1が雨水に濡れた場合には、図3に示すように親水性インク層5を通して着色疎水性インク層4の色彩が色彩変化部3の色彩として見える。その結果、着色疎水性インク層4の色彩によってあらわされる第二の模様Bを視認することができる。   When the shoe 1 gets wet with rain water, the color of the colored hydrophobic ink layer 4 appears as the color of the color changing portion 3 through the hydrophilic ink layer 5 as shown in FIG. As a result, the second pattern B represented by the color of the colored hydrophobic ink layer 4 can be visually recognized.

着色疎水性インク層4の色彩は単色で構成しても良いが、複数の色を用いて構成したものであっても好ましい。   The color of the colored hydrophobic ink layer 4 may be composed of a single color, but is preferably composed of a plurality of colors.
