Description
表1に示す組成のAg合金薄膜、即ち、Ag-Nd-In合金薄膜(Nd及びInを含有するAg合金薄膜)〔No.1〜5 〕、Ag-Gd-In合金薄膜〔No.6〜10〕、及び、 Ag-Y-In 合金薄膜〔No.11 〜15〕を作製し、Nd,Gd,Yの添加量(含有量)と薄膜の溶融温度、熱伝導率、反射率、BCA (Burst Cutting Area )方式によるマーキング(以下、 BCAマーキングという)時のレーザーパワーとの関係を調べた。
前記例1の場合と同様の作製方法により、表2に示す組成のAg合金薄膜、即ち、Ag-Nd-In合金薄膜〔No.1a 〜3a〕、Ag-Nd-Sn合金薄膜〔No.4a 〜6a〕を作製し、前記例1の場合と同様の測定方法により、薄膜の溶融温度、熱伝導率および反射率を測定し、前記例1の場合と同様の方法により、 BCAマーキング時のレーザーパワーを調べた。
前記例1の場合と同様の作製方法により、表3に示す組成のAg合金薄膜、即ち、Ag-Nd-In合金薄膜〔No.1b 〕、Ag-Nd-In-Bi 合金薄膜〔No.2b 〜4b〕、Ag-Nd-In-Sb 合金薄膜〔No.5b 〜7b〕を作製した。膜厚はいずれも100nm とした。この薄膜について、波長405nm における反射率を測定し、そして、環境試験を行い、この環境試験後の薄膜について波長405nm における反射率を測定し、これにより環境試験による反射率の変化量(低下量)を求めた。このとき、環境試験の条件は、温度80℃,湿度85%RHで、保持時間は96時間とした。
4--全反射膜層(Ag合金)、5--ポリカーボネート基体。
