染料モノマー1を0.08g、ポリマーA4.61g及びプロピレングリコールモノメチルエーテルアセテート2.31gを混合し、染料モノマー混合溶液Bを調製した。

実施例3において、染料モノマー1の代わりに染料モノマー2を、プロピレングリコールモノメチルエーテルアセテートの代わりに1-メトキシ-2-プロパノールを用いた以外は同様の実験を行い、化合物7由来のモノマー単位を含む染料ポリマー2を得た。
実施例3で得た染料ポリマー1の耐熱性を下記のようにして評価した。
即ち、実施例3で得た染料ポリマー1 3.0gとプロピレングリコールモノメチルエーテルアセテート4.0gを混合し、染料ポリマー溶液を調製した。調製したポリマー溶液を3インチのガラスウエハー(コーニング社製イーグルXG)にスピンコートした後、90℃に加熱したホットプレート上で90秒間乾燥して膜厚1ミクロンの薄膜を得た。得られた薄膜を、分光光度計(島津製作所製分光光度計UV-2550)を用いて極大吸収波長での吸光度(λa)を測定し、その後、230℃に加熱したホットプレート上で30分間加熱した後、再度、極大吸収波長での吸光度(λb)を測定した。得られたλaとλbの値から下記式より染料残存率(%)を求めた。その結果を表2に示す。
染料残存率(%)=(λb/λa)×100
実施例4において、実施例3で得た染料ポリマー1の代わりに比較例4で得た染料ポリマー2を、プロピレングリコールモノメチルエーテルアセテートの代わりに1-メトキシ-2-プロパノールを用いた以外は、同様の方法によって染料残存率(%)を求めた。得られた結果を実施例4の結果と併せて表2に示す。
撹拌装置、冷却管、温度計、窒素導入管を備えた2000mlの丸底フラスコにプロピレングリコールモノメチルエーテルアセテート(ダイセル(株)製)105gを入れ、窒素気流下にて、内温が95℃になるまで加熱した。次いで、実施例1で得られた染料モノマー1 15g、メタクリル酸メチル(和光純薬工業(株)製)285g、2,2’-アゾビス(2-メチルプロピオン酸メチル)(商品名V-601:和光純薬工業(株)製)15gを混合し、該混合溶液を95℃にて2時間かけて丸底フラスコに滴下した。その後、得られた溶液を95℃にて2時間反応させた。反応後、室温まで冷却し、酢酸エチル1000gに溶解した。該混合溶液をn-ヘキサン4600ml中に注入して生じた沈殿物をろ取、減圧下にて乾燥し、約5重量部の染料モノマー1を含む染料ポリマー3 315gを得た。
実施例5で得た染料ポリマー3 0.5重量部と市販のメタクリル酸メチル樹脂(アクリペットMD001:三菱レイヨン製)99.5重量部とを、同方向回転二軸押出機を用いて溶融混合し、着色した樹脂ペレットを得た。次いで、得られた樹脂ペレットを電動式射出成形機によって加工し、150mm×150mm×t2mmの着色板を作成した。
実施例6で作成した成形板を40mm×30mm×t2mmの大きさに裁断した後、エタノール50部とイオン交換水50部を混合したエタノール水溶液80ml中に浸漬し、40℃の恒温槽中で200時間保管した。保管中、1時間毎に恒温槽よりエタノール水溶液を取り出し、分光光度計(島津製作所製製分光光度計UV-2500)を用いて、エタノール水溶液の分光スペクトルを測定した。測定サンプルの最大吸収波長における吸光度(λa)と予め測定したグラム吸光係数(ε)を用いて、エタノール水溶液中に溶出した染料モノマー1の重量を算出し、浸漬させた着色板中に含まれる染料モノマー1の重量を基準とした時の溶出率(%)を下記式により算出した。結果を表3に示す。
溶出率(%)=[(λa×0.08/ε)/(着色板に含まれる染料の重量)]×100
※着色板中に含まれる染料の重量 = 板の重さ×0.00025
実施例6で作成した着色板を65mm×65mm×t2mmに裁断し、JIS B7754:1991に規定する装置(アトラス社製:Ci4000)を使用し、下記条件でキセノンアーク灯式による促進耐候性試験を実施した。
