上記親水処理有機表面は、例えば、ラジカル反応性基を有するシランカップリング剤を含む第1処理剤、および、ラジカル反応性基および有機カチオン性基を有するカチオン性化合物と、ラジカル反応性基および有機アニオン性基を有するアニオン性化合物と、を含む第2処理剤、を含む、親水化処理剤セットを用いることによって、形成することができる。
例えば上記親水化処理剤セットを用いて、基材の表面に上記第1処理剤を塗装し(第1処理剤塗装工程)、次いで、第1処理剤が塗装された表面に上記第2処理剤を塗装する(第2処理剤塗装工程)ことによって、親水化処理有機表面を得ることができる。以下、親水化処理剤セットについて詳述する。
上記親水化処理剤セットを構成する第1処理剤は、ラジカル反応性基を有するシランカップリング剤を含む。上記ラジカル反応性基を有するシランカップリング剤は、分子中に反応性シリル基とラジカル反応性基の両方を有する化合物である。反応性シリル基として、加水分解によりシラノール基を生成する基が挙げられる。反応性シリル基の具体例として、例えば、トリアルコキシシリル基(アルコキシ基に含まれる炭素数は1~7が好ましい)、ジアルコキシアルキル基(アルコキシ基に含まれる炭素数は1~7が好ましく、アルキル基に含まれる炭素数は1~7が好ましい)が挙げられ、より具体的には、トリメトキシシリル基、トリエトキシシリル基、トリプロポキシシリル基、トリス(2-メトキシエトキシ)シリル基、ジメトキシアルキルシリル基、ジエトキシアルキルシリル基、ジプロポキシアルキルシリル基、ビス(2-メトキシエトキシ)アルキルシリル基(上記アルキル基は、炭素数1~7の直鎖状または分枝状アルキル基であってよい)などが挙げられる。

などが挙げられる。
上記親水化処理剤セットを構成する第2処理剤は、ラジカル反応性基および有機アニオン性基を有するアニオン性化合物、および、ラジカル反応性基および有機カチオン性基を有するカチオン性化合物、を含むのが好ましい。これにより、基材に対して有機アニオン性基および有機カチオン性基を導入することができるため、親水性が発揮される表面が形成されることとなる。

ビニルスルホン酸、
N-t-ブチルアクリルアミドスルホン酸リチウム、

上記カチオン性化合物が有する有機カチオン性基として、例えば第4級アンモニウムカチオン性基が挙げられる。なお本明細書における「有機カチオン性基」とは、有機化合物が有するカチオン性基を意味する。本明細書における「有機カチオン性基」は、無機化合物中に含まれる陽イオン基と区別する意図で用いられる。第2処理剤に上記カチオン性化合物が含まれることによって、形成される親水処理有機表面は、有機カチオン性基を有することとなる。上記有機カチオン性基は、前記親水処理有機表面を構成する炭素原子(具体的には、カチオン性化合物に含まれる炭素原子)に結合している。カチオン性化合物は、シランカップリング剤を介して基材に結合しているため、水等による頻繁な洗浄によっても脱離し難い。よって、親水性は長期にわたって発揮され易くなる。

上記第1処理剤、第2処理剤は、含まれる成分がラジカル反応性官能基を有する場合は、さらにラジカル重合開始剤を含むのが好ましい。ラジカル重合開始剤は、光または熱により分解し、ラジカルを発生させる化合物である。ラジカル重合開始剤には、光により分解する光ラジカル重合開始剤と、熱により分解する熱ラジカル重合開始剤に分類される。ラジカル重合開始剤は、水溶性であることが好ましい。

次いで、上記で調製した第2処理剤を塗布し、その後、高圧水銀ランプを用いて積算光量が1000mJ/cm2のエネルギーとなる紫外線照射を行うことにより、陶器の表面に親水処理有機表面を形成した。
実施例2~12および比較例1~3では、シランカップリング剤の種類、および、アニオン性化合物、カチオン性化合物、重合開始剤などの種類および量などを、下記表に従い変更したこと以外は、実施例1と同様にして、親水処理有機表面を形成した。
pH7前後における親水処理有機表面のゼータ電位を、市販のゼータ電位計であるELSZ-2000ZS(大塚電子社製)を用いて測定し、測定結果の近似曲線からpH=7における値を算出することにより、pH=7におけるゼータ電位(mV)を求めた。
