○・・・指紋の跡が付かない
×・・・指紋の跡が付く
表1示す種類の原材料を表1に示す組成で使用したこと以外は実施例1と同様にして樹脂組成物を作製した。得られた組成物について、実施例1と同様に引張せん断接着強さの測定及び剥離試験、表面保護膜剥離試験及び表面硬化性試験を行った。それらの結果を表1に示す。
BDK:ベンジルジメチルケタール(チバ スペシャルティ ケミカルズ社製IRGACURE651)
NIPAM:N−イソプロピルアクリルアミド(興人社製NIPAM)
ポリビニルピロリドンK−30:ポリビニルピロリドン(日本触媒社製K−30)
ポリビニルピロリドンK−85:ポリビニルピロリドン(日本触媒社製K−85)
ポリビニルピロリドンK−90:ポリビニルピロリドン(日本触媒社製K−90)
実施例2及び6の樹脂組成物を使用し、実施例1と同様に剥離試験体AおよびBを作製し、温水の温度40℃、50℃、60、70℃を変えて剥離試験および表面保護膜剥離試験を行った。その結果を表2に示す。その結果、いずれの温度でも剥離性を有していた。
実施例2の樹脂組成物を用いて150mm×150mm×2mmの耐熱パイレックスガラスと実施例1で用いた青板ガラスをダミーガラスとして実施例1と同様に接着硬化させた。この接着試験体の耐熱パイレックスガラス部分のみをダイシング装置を使用して10mm角に切断した。切断中に耐熱パイレックスガラスの脱落は発生せず、良好な加工性を示した。耐熱パイレックスガラス部分のみを切断した接着試験体を80℃の温水に浸漬したところ、60分ですべて剥離した。
また、その剥離した切断試験片を無作為に10個取り出し、その切断試験片の裏面(樹脂組成物で仮固定した面)の各片を光学顕微鏡を用いて観察し、ガラスが欠けている箇所の最大幅を測定し、その平均値と標準偏差を求めた。その結果を、表3に示す。
ホットメルト型接着剤(日化精工社製アドフィックスA)を90℃に加熱し溶解させて、150mm×150mm×2mmの耐熱パイレックスガラスと実施例1で用いた青板ガラスを接着させた。この接着試験体の耐熱パイレックスガラス部分のみをダイシング装置を使用して10mm角に切断した。切断中に耐熱パイレックスガラスの脱落は発生せず、良好な加工性を示した。その試験片をN-メチルピドリロン溶液に1日浸漬し、切断試験片を回収し、実施例14と同様に剥離した切断試験片を任意に10個取り出し、その切断試験片の裏面(ホットメルト型接着剤で仮固定した面)の各片を光学顕微鏡を用いて観察し、ガラスが欠けている箇所の最大幅を測定し、その平均値と標準偏差を求めた。その結果を、表3に示す。
UV硬化型PET粘着テープを使用して150mm×150mm×2mmの耐熱パイレックスガラスを接着させた。この接着試験体の耐熱パイレックスガラス部分のみをダイシング装置を使用して10mm角に切断した。その試験片の粘着テープ部分に紫外線を照射させることにより粘着力を低下させ、その切断試験片を回収した。その切断試験片を実施例14と同様に剥離した切断試験片を任意に10個取り出し、その切断試験片の裏面(粘着テープで仮固定した面)の各片を光学顕微鏡を用いて観察し、ガラスが欠けている箇所の最大幅を測定し、その平均値と標準偏差を求めた。その結果を、表3に示す。
