(ロイコ染料A)一般式(1)で表される第一ロイコ染料である3−ジ(n−ブチル)アミノ−6−メチル−7−アニリノフルオラン
ビス(3−アリル−4−ヒドロキシフェニル)スルホン45部、スルホン変性ポリビニルアルコールの10%水溶液50部、及び水25部からなる組成物をウルトラビスコミルを用いて平均粒子径が0.3μmとなるまで粉砕して呈色剤分散液を得た。
複合粒子分散液80部、呈色剤分散液70部、ステアリン酸アミドの30%分散液70部、固形分濃度48%のスチレン−ブタジエン系ラテックス(ポリラック752A、三井東圧化学工業社製)30部及び水30部からなる組成物を混合して感熱記録層用塗液を得た。
カオリン(商品名:UW−90、EC社製)の60%分散液(平均粒子径0.5μm)30部、カルボキシ変性ポリビニルアルコール(商品名:ゴーセナールT−330、日本合成化学工業社製)の10%水溶液350部、ステアリン酸亜鉛分散液(商品名:ハイドリンZ−7−30、固形分濃度31.5%、中京油脂社製)15部、ポリアミドエピクロルヒドリンの20%水溶液10部、及び水200部からなる組成物を混合して保護層用塗液を得た。
青色透明なポリエチレンテレフタレートフィルム(商品名:メリネックス912、厚さ175μm、透過測定色彩値a*=−6.4、b*=−12.9、ヘイズ値3%、帝人デュポン社製)の片面上に、感熱記録層用塗液をスロットダイコーターを用いて乾燥後の塗布量が20.0g/m2となるように塗布及び乾燥して感熱記録層を設け、その上に保護層用塗液をスロットダイコーターを用いて乾燥後の塗布量が3.5g/m2となるように塗布及び乾燥して保護層を設けて感熱記録体を得た。
実施例1の感熱記録用塗液の調製において、複合粒子分散液80部に代えて下記のロイコ染料分散液25部を用いた以外、実施例1と同様に感熱記録体を得た。
3−ジ(n−ブチル)アミノ−6−メチル−7−アニリノフルオラン10.0部、3−ジエチルアミノ−7−(N,N−ジベンジルアミノ)フルオラン1.0部、3,3−ビス(4−ジエチルアミノ−2−エトキシフェニル)−4−アザフタリド2.5部、3−〔2,2−ビス(1−エチル−2−メチルインドール−3−イル)ビニル〕−3−(4−ジエチルアミノフェニル)フタリド1.0部、3−ジエチルアミノ−6,8−ジメチルフルオラン4.0部、スルホン変性ポリビニルアルコールの10%水溶液15部、及び水10部からなる組成物をウルトラビスコミルを用いて平均粒子径が0.6μmとなるまで粉砕した。
実施例1の感熱記録体の作製において青色透明なポリエチレンテレフタレートフィルムに代えて、無色透明なポリエチレンテレフタレートフィルム(商品名:HMW−100、厚さ175μm、透過測定色彩値a*=+0.23、b*=+2.72、ヘイズ値5%、帝人社製)を用いた以外は、実施例1と同様にして感熱記録体を得た。
感熱印字試験装置TH−PMD(大倉電機社製)を用いて、1ライン記録時間:5msec、副走査線密度:8ライン/mm、ドット当たり印加エネルギー:0.5mJの条件下に256ラインのベタ印字を施し、低印加エネルギー記録を行った。また、別に、1ライン記録時間:5msec、副走査線密度:8ライン/mm、ドット当たり印加エネルギー:2.0mJの条件下に256ラインのベタ印字を施し、高印加エネルギー記録を行った。各記録部の色彩値a*、b*を瞬間マルチ測光システムMCPD(大塚電子社製)(条件2度視野、光源D65)で測定し、各記録部a*の差Δa*、各記録部b*の差Δb*を求めた。Δa*、Δb*が共に1.5以下であれば問題のないレベルであり、より好ましくはΔa*、Δb*が共に0.5以下である。
上記の低印加エネルギー記録部の色彩値a*、b*を瞬間マルチ測光システムMCPD(大塚電子社製:条件2度視野)でD65光源とA光源の2種の光源により色彩値a*、b*を測定し、その差Δa*、Δb*を求めた。Δa*、Δb*が共に1.5以下であれば問題のないレベルであり、より好ましくはΔa*、Δb*が共に0.5以下である。
上記の高印加エネルギー記録部の濃度をマクベス濃度計(商品名:TR−927J型マクベス社製)のビジュアルモードで透過濃度を測定した。
