<(A)成分>
本発明の(A)成分は、湿気により架橋反応が開始される1分子中に加水分解性シリル基を2以上有する有機重合体である。加水分解性シリル基は、有機重合体の末端又は側鎖に結合してよいが、光硬化性樹脂組成物の硬化性に優れるという観点から好ましくは末端に結合しているものがあげられる。
本発明の(B)成分の光照射により酸を発生する化合物とは、活性エネルギー線の照射により、(A)成分を架橋させることができる酸性物質を放出することができる化合物である。
本発明の(D)成分は、本発明の光硬化性樹脂組成物に深部硬化性を付与するもので、ケイ素原子に、アリール基又は複素環が1以上且つ1以上の水酸基が直接結合している化合物(但し、ポリシロキサンではない)及び少なくとも2以上のシラノール基を有するポリシロキサンからなる群から選択される化合物である。なお、前記アリール基とは、例えば炭素数6〜12の芳香族環構造の官能基などがあげられ、より具体的には、フェニル基、ベンジル基、トリル基、キシリル基などが挙げられる。また、前記複素環としては、硫黄原子、窒素原子、酸素原子のいずれかを少なくとも有する三員環から十員環までの環構造等があげられる。
各成分を表1に示す質量部で採取し、常温にてミキサーで60分混合し、光硬化性樹脂を調製し、各種物性に関して次のようにして測定した。数値は全て質量部で標記する。
<(A)成分>
a−1:粘度(25℃)が700Pa・sである両末端アルコキシシリル基含有ポリイソブチレン樹脂(製品名EPION EP100S、株式会社カネカ製)
a−2:粘度(25℃)が230Pa.sである両末端アルコキシシリル基含有アクリル共重合体(製品名SA100S、株式会社カネカ製)
<(B)成分>
b−1:スルホン酸エステル系光酸発生剤(製品名NT−1TF、サンアプロ株式会社製)
<(C)成分>
c−1:トリス(2−アクリロイルオキシエチル)イソシアヌレートとビス(2−アクリロイルオキシエチル)−2−ヒドロキシエチルイソシアヌレートの混合物(M−313、東亜合成株式会社製)
c−2:ベンゾチアゾール(試薬)
<(C)成分の比較>
c’−1:N,N−ジメチルPトルイジン(試薬)
c’−2:N,N−ジエチルPトルイジン(試薬)
c’−3:1,2,3,4−テトラヒドロキノリン(試薬)
<(D)成分>

d−2:シラノール基を両末端に有するポリジメチルシロキサン:25℃における粘度16〜32cSt、分子量550、製品名DMS−S12、Gelest,Lnc.製
10mm×10mmのガラス板に各光硬化性樹脂組成物を500μmの厚みになるように塗布する。次に、紫外線照射機を用いて60kJ/cm2の積算光量の光を照射した。その後、試験片表面のべたつきがなくなるまでの時間を確認し、評価した。なお、べたつきがなくなったかどうかの判断は、指による接触試験で判断した。なお、タックフリータイムは、15分未満が好ましい。
各光硬化性樹脂組成物を黒色軟膏容器に充填し、25℃環境下で4日間密閉保存する。その後、容器を開封し、下記基準に基づき目視で評価し、その結果を表1に示す。
<評価基準>
○:光硬化性樹脂組成物の流動性が確認できた。
×:光硬化性樹脂組成物がゲル化して流動しなくなっていた。
弱塩基性化合物(N,N−ジメチルPトルイジン、N,N−ジエチルPトルイジン、1,2,3,4−テトラヒドロキノリン)を用いたものであるが、タックフリーが遅く、光硬化性が劣ることが確認された。
