上記中間膜は、可塑剤を含むことが好ましい。上記暗部の領域は、可塑剤を含むことが好ましい。上記明部の領域は、可塑剤を含むことが好ましい。上記暗部の領域に含まれる可塑剤と上記明部の領域に含まれる可塑剤とは同一であってもよく、異なっていてもよい。上記可塑剤は、1種のみが用いられてもよく、2種以上が併用されてもよい。
上記中間膜は、必要に応じて酸化防止剤、紫外線遮蔽剤、光安定剤、難燃剤、帯電防止剤、顔料、染料、接着力調整剤、耐湿剤、蛍光増白剤及び赤外線吸収剤等の添加剤を含んでいてもよい。これらの添加剤は、1種のみが用いられてもよく、2種以上が併用されてもよい。
本発明に係る中間膜の厚みは特に限定されない。実用面の観点からは、中間膜の厚みは、好ましくは0.1mm以上、より好ましくは0.25mm以上、好ましくは3mm以下、より好ましくは1.5mm以下である。中間膜の厚みが上記下限以上であると、合わせガラスの耐貫通性が高くなる。中間膜の厚みが上記上限以下であると、中間膜の透明性がより一層良好になる。
図3に、本発明の第1の実施形態に係る合わせガラス用中間膜を含む多層の中間膜を用いた合わせガラスの一例を模式的に断面図で示す。
PVB(1)(n−ブチルアルデヒドを使用、PVAの平均重合度1700、水酸基の含有率30.4モル%、アセチル化度0.8モル%、アセタール化度(ブチラール化度)68.8モル%)

中間膜の作製:
PVB(1)100重量部と、PVB(2)0.87重量部と、可塑剤(3GO)40重量部と、紫外線遮蔽剤(Tinuvin326)0.2重量部と、酸化防止剤(BHT)0.2重量部とを混合し、組成物を得た。
得られた中間膜を、縦80mm×横80mmに切り出した。次に、2枚の透明なフロートガラス(縦80mm×横80mm×厚み2.5mm)の間に中間膜を挟み込み、真空ラミネーターにて90℃で30分間保持し、真空プレスし、積層体を得た。積層体において、ガラスからはみ出た中間膜部分を切り落とし、合わせガラスを得た。
ポリビニルアセタール樹脂の種類及び含有量を下記の表1に示すように設定したこと以外は実施例1と同様にして、中間膜及び合わせガラスを作製した。
(1)透過型電子顕微鏡(TEM)での観察
中間膜をトリミングした小片を2%オスミウム酸水溶液で、60℃で12時間染色した後に洗浄し、中間膜の厚み方向における中央部分を、厚み方向とは垂直方向に、クライオミクロトーム(LEICA社製、本体:UCT、クライオチャンバー:EMFCS)により、小片温度−20℃で厚み70nmの切片を切り出し、支持膜を張ったシートメッシュ上に載せ、測定サンプルとした。
A:海島状態である
B:海島状態ではない
得られた合わせガラスについて、変角光度計(Murakami color research Lab社製「GONIOPHOTOMETER GP−200」)を用いて、Detector角度30°、High Volt 900、Sensitivity 900の条件で、散乱値を測定した。散乱値が低いほど、くもりの程度が少なく、透明性に優れていることを示す。なお、散乱値は110以下であることが好ましく、90以下であることがより好ましく、50以下であることが更に好ましい。
