摘要:
Disclosed is a reflective film laminate, which has a pure Ag film or an Ag-based alloy film as a first layer on a base body, and an oxide film of a metal of one or more kinds selected from among Zr, Cr, Nb, Hf, Ta, V, Ni, Mo, W, Al and Si, as a second layer on the first layer. The thickness of the second layer is 0.1 to 10 nm, and deterioration of the reflection ratio of reflective film laminate is 30% or less by having the second layer provided therein. The reflective film laminate is provided with a protection film, which has a high initial reflection ratio, excellent sulfuration resistance and heat resistance, and an extremely small number of pin holes. As a result, the reflection ratio of the reflective film laminate is not easily deteriorated due to aggregation of Ag atoms of the Ag film.

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.

摘要:
Disclosed is an Al alloy reflective film which has a higher reflectance than that of pure Al films when produced by sputtering, excels in alkali resistance, acid resistance, and moisture resistance, and therefore less suffers from the reduction in reflectance even when a protective coating is not applied. Specifically disclosed is an Al alloy reflective film which contains at least one element selected from Sc, Y, La, Gd, Tb, and Lu in a total amount of from 0.4 to 2.5 atomic percent, with the remainder being Al and inevitable impurities. The Al alloy reflective film has a film surface roughness of 4 nm or less as measured with an atomic force microscope. Also disclosed are an automotive lighting device and an illumination device each provided with the reflective film. Further disclosed is an Al alloy sputtering target for use in the formation of the reflective film.
