従来の光輝フィルムは何れもメタリック感を持たせたものや、干渉色を反射するように作られ、光沢性に優れている。しかし、表面での反射率が高すぎるために、反射輝度は高いが、穏やかなメタリック感や穏やかな干渉色の反射光を発するということがないため、防眩性が要求されるような用途での使用や、あるいは意匠性の観点から防眩性が要求される用途には不向きであった。また、従来の防眩性フィルムはCRTディスプレーや液晶表示板などの表面に貼って、光の反射を和らげる目的で使用されてきているが、これらの防眩性フィルムは光を拡散反射させるのみで、特に意匠性はなく、また装飾用途などに使用できるものではない。   All of the conventional glitter films have a metallic feeling and are made to reflect interference colors, and are excellent in gloss. However, since the reflectance at the surface is too high, the reflection brightness is high, but it does not emit a reflected light with a gentle metallic feeling or a gentle interference color, so it is used in applications where anti-glare properties are required. It is unsuitable for the use which requires anti-glare property from the viewpoint of use of, or design nature. In addition, conventional anti-glare films have been used for the purpose of softening light reflection by sticking to the surface of CRT displays and liquid crystal display panels, but these anti-glare films only diffuse and reflect light. In particular, it has no design properties and cannot be used for decorative purposes.

In addition, when the transparent film is a transparent elastic resin and the color developing layer is a transparent elastic resin containing a glitter pigment or an elastic glitter color developing film, it is possible to obtain a follow-up property as the fabric stretches.

以下、本発明の一実施の形態を、図1および図2を用いて具体的に説明する。
図1において、1は本実施の形態の防眩性光輝フィルムで、この防眩性光輝フィルム1は発色層2の上に表面に微小な径の無数の半球状凸部3を有する透明フィルム4が積層されて作られている。この防眩性光輝フィルム1は前記発色層2の裏面に接着剤層5を塗布し、この接着剤層5を介して生地などの被着体6に装着される。
Hereinafter, an embodiment of the present invention will be specifically described with reference to FIGS. 1 and 2.
In FIG. 1, reference numeral 1 denotes an antiglare glitter film of the present embodiment. This antiglare glitter film 1 has a transparent film 4 having innumerable hemispherical convex portions 3 with minute diameters on the surface of the color developing layer 2. Are made by laminating. This anti-glare glitter film 1 has an adhesive layer 5 applied to the back surface of the color developing layer 2 and is attached to an adherend 6 such as a fabric through the adhesive layer 5.

図2は上記防眩性光輝フィルム1の製造手順を示し、図2(A)に示すポリエチレンテレフタレートフィルムや紙などの耐熱性シート7の上にポリエチレンなどの熱軟化性樹脂層8を積層してなる基材フィルム9が用いられ、この基材フィルム9を熱軟化性樹脂層8の融点付近で加熱して熱軟化性樹脂層8を軟化させた状態で図2(B)に示すように熱軟化性樹脂層8の上から微小球10を撒布し、この微小球10を熱軟化性樹脂層8に付着させる。そして、かかる状態で熱軟化性樹脂層8の融点を超える温度に基材フィルム9を加熱することによって熱軟化性樹脂層8を溶融させ、前記微小球10を自重でその直径の約30〜70%を熱軟化性樹脂層8に埋没させる。この微小球10の直径は前記熱軟化性樹脂層8の厚みと関係し、特に限定されるものではないが、1〜500μmの範囲のものが利用しやすく、また比重およびコストの面からガラス微小球が好ましく利用できる。そして、前述のように微小球10を熱軟化性樹脂層8に埋没させた後、基材フィルム9を冷却させて熱軟化性樹脂層8に微小球10を固着させ、その後図2(C)に示すように微小球10が露出する熱軟化性樹脂層8の上から微小球10を覆うように接着剤層11を塗布により積層する。そして、この接着剤層11を乾燥硬化させた後、図2(D)に示すように接着剤層11を微小球10とともに熱軟化性樹脂層8から剥離することにより基材フィルム9の熱軟化性樹脂層8の表面に図2(E)に示すようにほぼ半球状の無数の凹部12が形成される。このようにして得られた基材フィルム9に対し熱軟化性樹脂層8の上から前記凹部12を完全に埋め且つ凹部12上端から適当厚みを備えるように図2(F)に示すように透明樹脂を用いて溶剤コーティングや溶融押出しコーティングにより透明フィルム4を形成する。その後、図2(G)に示すように透明フィルム4の上に発色層2を積層する。この発色層2の積層手段としては着色剤を含有する樹脂を用いて透明フィルム4の上に溶剤コーティングや溶融押出しコーティングにより積層する方法、あるいは光輝性の発色フィルムを接着剤を用いて透明フィルム4の上にラミネートする方法が採用される。発色層2に用いられる着色剤としては一般に光輝性顔料と呼ばれるものを使用する。光輝性顔料として酸化チタンをコーティングした雲母など、一般にパール顔料と呼ばれている顔料を使用する場合は、透明フィルム4の形成の際に、前記凹部12をほぼ完全に埋めるようにコーティングするのが好ましい。その理由としては、透明フィルム4の前記凹部14側とは反対側の面をフラットな状態に仕上げ、この透明フィルム4に積層される発色層2の光輝性顔料が平面状に配列されているのが好ましいからである。発色層2に使用される光輝性顔料としてはパール顔料と呼ばれている顔料の他に、金属薄膜の微細薄片や、多層に積層された干渉性薄膜の微細薄片などを使用できる。発色層2に対し白もしくは黒に着色した不透明層を積層すると光輝性顔料の発色が一層引き立つようになるが、不透明層は必ずしも必要ではない。また、発色層2は多層であっても良い。前述のように透明フィルム4に発色層2が積層されてなる防眩性光輝フィルムは図2(H)に示すように基材フィルム9から剥離されて完成となるが、防眩性光輝フィルムの実際の使用に当たっては図2(H)に示すように基材フィルム9から剥離された後、発色層2に接着剤層5を積層して防眩性光輝フィルムを様々な媒体に貼付したり、あるいは接着剤層5を介して衣類などに貼り付け、縫製するものである。   FIG. 2 shows a manufacturing procedure of the antiglare glitter film 1 and a heat softening resin layer 8 such as polyethylene is laminated on a heat resistant sheet 7 such as polyethylene terephthalate film or paper shown in FIG. A base film 9 is used, and the base film 9 is heated in the vicinity of the melting point of the heat softening resin layer 8 to soften the heat softening resin layer 8 as shown in FIG. The microspheres 10 are spread over the softening resin layer 8, and the microspheres 10 are attached to the heat softening resin layer 8. In such a state, the base film 9 is heated to a temperature exceeding the melting point of the thermosoftening resin layer 8 to melt the thermosoftening resin layer 8, and the microspheres 10 are about 30 to 70 in diameter with their own weight. % Is buried in the thermosoftening resin layer 8. The diameter of the microspheres 10 is related to the thickness of the thermosoftening resin layer 8 and is not particularly limited. However, those having a diameter in the range of 1 to 500 μm are easy to use, and the glass microspheres are used in terms of specific gravity and cost. A sphere can be preferably used. Then, after the microspheres 10 are embedded in the thermosoftening resin layer 8 as described above, the base film 9 is cooled to fix the microspheres 10 to the thermosoftening resin layer 8, and then FIG. 2 (C). The adhesive layer 11 is laminated by coating so as to cover the microspheres 10 from above the heat-softening resin layer 8 from which the microspheres 10 are exposed. Then, after the adhesive layer 11 is dried and cured, the adhesive film 11 is peeled from the heat-softening resin layer 8 together with the microspheres 10 as shown in FIG. As shown in FIG. 2E, innumerable concave portions 12 that are substantially hemispherical are formed on the surface of the conductive resin layer 8. As shown in FIG. 2 (F), the base film 9 thus obtained is transparent as shown in FIG. 2 (F) so as to completely fill the concave portion 12 from above the heat-softening resin layer 8 and to have an appropriate thickness from the upper end of the concave portion 12. The transparent film 4 is formed by solvent coating or melt extrusion coating using a resin. Thereafter, the coloring layer 2 is laminated on the transparent film 4 as shown in FIG. As a means for laminating the color developing layer 2, a method of laminating a transparent film 4 with a resin containing a colorant on the transparent film 4 by solvent coating or melt extrusion coating, or a glittering color developing film using an adhesive. A method of laminating on is adopted. As the colorant used for the color forming layer 2, a so-called bright pigment is generally used. When using a pigment generally referred to as a pearl pigment such as mica coated with titanium oxide as a bright pigment, it is necessary to coat the concave portion 12 so as to be almost completely filled when the transparent film 4 is formed. preferable. The reason is that the surface of the transparent film 4 opposite to the concave portion 14 is finished in a flat state, and the glitter pigments of the coloring layer 2 laminated on the transparent film 4 are arranged in a planar shape. Is preferable. As the bright pigment used in the color forming layer 2, in addition to a pigment called a pearl pigment, fine thin pieces of metal thin films, fine thin pieces of coherent thin films laminated in multiple layers, and the like can be used. When an opaque layer colored white or black is laminated on the color developing layer 2, the color of the glitter pigment is further enhanced, but the opaque layer is not always necessary. The color developing layer 2 may be a multilayer. As described above, the antiglare glitter film in which the coloring layer 2 is laminated on the transparent film 4 is peeled off from the base film 9 as shown in FIG. In actual use, after being peeled off from the base film 9 as shown in FIG. 2 (H), the adhesive layer 5 is laminated on the coloring layer 2 and the anti-glare glitter film is attached to various media. Alternatively, it is attached to clothing or the like via the adhesive layer 5 and sewn.

ところで、前記透明フィルム4とは透明ないし半透明なフィルムを含み、前記発色層2の色が確認できるものであれば、光透過度などで示される透明性について特に規定するものではない。   By the way, if the transparent film 4 includes a transparent or translucent film and the color of the coloring layer 2 can be confirmed, the transparency indicated by the light transmittance is not particularly specified.

After the glass microspheres are spread on almost one surface and the glass microspheres are attached on the polyethylene film, the base film to which the glass microspheres are attached is heated at 140 ° C. for 2 minutes to melt the polyethylene film. About 50% of the diameter of the sphere was embedded in the polyethylene film part. Thereafter, the substrate film was cooled, and then the surface of the glass microspheres was washed with water to remove the glass microspheres not buried in the polyethylene film portion. Next, an acrylic resin is uniformly laminated with a thickness of 60 μm as an adhesive layer so as to cover the glass microspheres from above the polyethylene film from which the glass microspheres are exposed. Peeled off. As a result, a base film having an infinite number of hemispherical recesses with a radius of about 30 μm on the entire surface of the polyethylene film portion was obtained. Next, on the surface of the base film having the recesses, polycarbonate urethane resin is used as an isocyanate curing agent and dimethylformamide as a solvent, and the dry film thickness of the portion where the recesses are completely filled and protruded from the recesses is about 10 μm after drying.
