実施例1~3および比較例1~3の組成および基材を表1にまとめる。
(1)接触角
上記実施例および比較例で得られた表面親水性基材の塗膜表面に直径2mmの水滴を落とし、1分間放置後、接触角計(協和界面科学株式会社の商品名「CA-S150型」)にて測定した。なお、アルミ板、人工皮革(出光テクノオファイン製サプラーレ)および耐衝撃性ポリスチレン(HIPS)の各基材の接触角は、以下のとおりである。
接触角[度] アルミ板: 91
人工皮革:106
HIPS: 87
上記実施例および比較例等で得られた表面親水性基材の塗膜表面に0.2mLのイオン交換水を滴下した30秒後に、摩擦感テスター(カトーテック株式会社製、型式:KES-SE)を用いて、以下の試験条件下、摩擦係数μをモニターした。
センサー:ピアノ線
荷重 :50[g]
速度 :10[mm/秒]
平均摩擦係数(MIU)は、表面をこする時に感じる滑りやすさ、滑りにくさと相関性がある。この値が大きくなるほど滑りにくくなる。
上記実施例および比較例で得られた表面親水性基材の塗膜表面の摩擦係数μをモニターした。次に、20mmのモニター幅において、摩擦係数μについて積分した。積分値をモニター幅(20mm)で除することによって、平均摩擦係数(MIU)を求めた。MIUの値が0.3以下のとき、滑り性が良好といえる。
平均摩擦係数の変動(MMD)は、表面をこする時に感じるなめらかさ、ざらつき感と相関性がある。この値が大きいほど表面がざらざらしている。
20mmのモニター幅において、平均摩擦係数(MIU)と摩擦係数μとの差異の絶対値を積分した。積分値をモニター幅(20mm)で除することによって、平均摩擦係数の変動(MMD)を求めた。MMDの値が0.015以下のとき、表面のなめらかさが良好といえる。
予め質量[A(g)]を測定した、上記実施例および比較例で得られた表面親水性基材を34℃、90%RHの条件下で恒温恒湿槽に5時間静置した後に質量[B(g)]を測定した。さらに、25℃、65%RHの条件下に2時間静置し、そのときの質量[C(g)]を測定し、単位質量当たりの吸湿性(g/g)および放湿性(g/g)を下記式に従って求めた。
放湿性(g/g)=(B-C)/A
上記実施例および比較例で得られた表面親水性基材を25℃のイオン交換水中に2時間浸漬した後、40℃の温風乾燥機にて乾燥させた。その後、表面親水性基材の塗膜表面を紙製ウェス(日本製紙クレシア製 S200)にて30回こすった。その後、接触角、平均摩擦係数(MIU)と平均摩擦係数の変動(MMD)、吸湿性および放湿性を求めた。それらの値が初期値の10%範囲内にあれば十分に耐久性があると判断できる。
一方、ポリアルキレンオキシド変性物のみからなる表面親水性基材においては(比較例1および2)、1回目の親水性評価および吸放湿性評価は良好な結果となったが、耐久性試験後の滑り性および吸放湿性は悪化し、その効果は持続せず、耐久性が低い結果となった。また、ポリオレフィン系樹脂のみからなる表面親水性基材においては(比較例3)、1回目の濡れ性、滑り性評価および吸放湿性評価でも不十分な結果となり、本発明の目的を達成することはできなかった。
