Description

（実施例１）
真空蒸着機を用いて、厚さ７５μｍのアクリルフイルム（「サンデュレン」カネカ製）に、インジウムを蒸着し、厚さ５００Åの金属層を形成することで、金属処理フィルム（Ｃ）を得た。
また、アクリル樹脂系粘着剤の主剤１００部にコロネートＬ（イソシアネート系硬化剤、日本ポリウレタン製）０．７５部、マルチラック黒（カーボンブラックのマレイン酸エステル系樹脂分散体、東洋インキ製）０．５部を配合・混合し黒色粘着剤を作成した。なお、粘着剤中のアクリル樹脂１００部に対してカーボンブラックは０．１部用いられている。次に、上記黒色粘着剤を、膜厚１００μｍの剥離シート（カイト化学株式会社製「ＴＳＭ−１１０Ｋ」）上に、コンマコーターを用いて、乾燥膜厚が約２０μｍとなるように塗工し、８０℃の熱風オーブン中で２分間乾燥し粘着剤層を形成した。さらに金属処理フィルム（Ｃ）の金属層と前記粘着剤層とを貼り合わせて、粘着シートを作成した。上記粘着シートから剥離シートを剥がし、厚さ３ｍｍの無色透明なアクリル板（「アクリライトＥ」三菱レイヨン社製）に貼合し成型用樹脂積層体を作成した。ここで黒色度を評価した。
さらに上記成型用樹脂積層体を、真空成型機「ＦＯＲＭＥＣＨ３００Ｘ」（成光産業製）を用いて、加熱温度１６０℃で一辺７ｃｍの正四角柱状の突起を、金属処理フィルム（Ｃ）が表側となるように真空成型し、樹脂成型物を得た。
Example 1
Using a vacuum vapor deposition machine, indium was vapor-deposited on a 75 μm thick acrylic film (manufactured by “Sanduren” Kaneka) to form a metal layer having a thickness of 500 mm, thereby obtaining a metal-treated film (C).
In addition, 100 parts of the main component of the acrylic resin-based adhesive is 0.75 parts of Coronate L (isocyanate-based curing agent, manufactured by Nippon Polyurethane), multi-lac black (carbon black maleate ester resin dispersion, manufactured by Toyo Ink). 5 parts were blended and mixed to create a black adhesive. In addition, 0.1 part of carbon black is used with respect to 100 parts of acrylic resin in the adhesive. Next, the black adhesive was applied on a release sheet having a film thickness of 100 μm (“TSM-110K” manufactured by Kite Chemical Co., Ltd.) using a comma coater so that the dry film thickness was about 20 μm. It was dried in a hot air oven at 80 ° C. for 2 minutes to form an adhesive layer. Further, the metal layer of the metal-treated film (C) and the pressure-sensitive adhesive layer were bonded together to create a pressure-sensitive adhesive sheet. The release sheet was peeled from the pressure-sensitive adhesive sheet and bonded to a colorless and transparent acrylic plate (“Acrylite E” manufactured by Mitsubishi Rayon Co., Ltd.) having a thickness of 3 mm to prepare a resin laminate for molding. Here, the blackness was evaluated.
Further, using the molding resin laminate, using a vacuum molding machine “FORMECH300X” (manufactured by Seiko Sangyo Co., Ltd.), a regular square pillar-shaped protrusion having a side of 7 cm at a heating temperature of 160 ° C., the metal-treated film (C) is the front side. As described above, vacuum molding was performed to obtain a resin molded product.
