Description
2,2’−[4,4’−シクロヘキシリデンビスフェノキシ]ジエタノール(バインダA−1)の調製
250mLの丸底フラスコに、ビスフェノールZ(26.835g)、エチレンカーボネート(18.32g)、および炭酸ナトリウム(0.05g)の混合物を入れた。この混合物を200℃で4時間加熱し、室温まで冷却した。得られた生成物をメタノール(300mL)に溶解し、蒸留したイオン水(600mL)中に沈殿させた。蒸留したイオン水で2回洗浄し、濾過し、40℃のオーブン中で一晩乾燥した後、27.5g(77.2%)の生成物を得た。プロトン核磁気共鳴分光法(NMR)のスペクトルより、所望の構造を有する生成物であることが確認された。
2,2−ビス(4−ヒドロキシエチルオキシフェニル)プロパン(バインダA−2)の調製
250mLの丸底フラスコに、ビスフェノールA(22.829g)、エチレンカーボネート(18.32g)、および炭酸ナトリウム(0.036g)の混合物を入れた。この混合物を約150℃で4時間加熱したが、反応が完了していないことが薄層クロマトグラフィーにより示された。温度を約190℃〜200℃に上げ、3時間反応させた後、室温まで冷却した。得られた生成物をメタノール(300mL)に溶解し、蒸留したイオン水(600mL)に沈殿させた。蒸留したイオン水で2回洗浄し、濾過し、40℃のオーブン中で一晩乾燥した後、23.6g(74.7%)の生成物が得られた。NMRスペクトルより、所望の構造を有する生成物であることが確認された。

100部のジルコニウム化合物(商標名:Orgatics ZC540)と、10部のシラン化合物(商標名:A110、日本ユニカー株式会社製)と、400部のイソプロパノール溶液と、200部のブタノールと、を含む下引き層のコーティング溶液を調製した。このコーティング溶液を、ホーニング処理した円筒状のアルミニウム基体にディップコーティングによって塗布し、150℃で10分間乾燥させ、膜厚0.1マイクロメートルの下引き層を形成した。
1部の2,2’−[4,4’−シクロヘキシリデンビスフェノキシ]ジエタノール(実施例1に従って調製したバインダA−1)と、1.4部のメラミン−ホルムアルデヒド樹脂(Cytec Industries社製のCymel303)と、1.6部のフェノール電荷輸送成分であるN,N’−ビス(3−ヒドロキシフェニル)−N,N’−ジフェニル−1,1’−ビフェニル−4,4’−ジアミンと、0.5部の酸触媒(King Industies社製のNacure5225)との混合物を、溶媒である13.8部の1−メトキシ−2−プロパノールに溶解した。0.45μmのPTFEフィルターで濾過した後、この溶液を感光体表面、具体的には電荷輸送層の上にカップコーティング(cup coating)により塗布し、その後140℃で40分間熱硬化させて、膜厚3μmのオーバーコート層を形成した。
2,2−ビス(4−ヒドロキシエチルオキシフェニル)プロパン(実施例2に従って調製したバインダA−2)をバインダとして用いてオーバーコート層を形成したこと以外は実施例3に記載したプロセスを繰り返すことで、感光体を作製した。
