    • A reflective film laminate is provided with high productivity and at low cost in which a protective film with minimized pinholes is provided to improve the alkali resistance and warm water resistance of the reflective film laminate including a pure Al film or an Al-based alloy film so that a reflectivity reduction resulting from the elution or oxidization of the Al film in an alkaline or warm water environment is less likely to occur. The reflective film laminate of the present invention includes, over a substrate, a pure Al film or an Al-based alloy film as a first layer, and an oxide film of a metal containing one or more elements selected from the group consisting of Zr, Cr, Y, Nb, Hf, Ta, W, Ti, Si, and Mo as a second layer over the first layer. The thickness of the second layer is 0.1 to 10 nm.
    • 以低成本提供反射膜层叠体,其中提供具有最小化的针孔的保护膜以提高包括纯Al膜或Al基合金膜的反射膜层压体的耐碱性和耐温水性, 在碱性或温水环境中由于Al膜的洗脱或氧化引起的反射率降低不太可能发生。 本发明的反射膜层叠体在基板上包括作为第一层的纯Al膜或Al基合金膜,以及含有选自Zr, Cr,Y,Nb,Hf,Ta,W,Ti,Si和Mo作为第一层上的第二层。 第二层的厚度为0.1〜10nm。
