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.

Disclosed are a separator for a fuel cell realizing both the high electrical conductivity and the corrosion resistance and enabling using stably for a long period of time in the fuel cell and a manufacturing method for it. The separator for a fuel cell 1 includes a substrate 2 composed of pure aluminum or aluminum alloy and a plating layer 3 formed on the substrate 2, wherein the plating layer 3 has a copper layer 3a formed in the substrate 2 side and a tin layer 3b formed on the copper layer 3a, the tin layer 3b is formed in an uppermost layer, the thickness of the copper layer 3a is 0.10 μm or above, and the value obtained by dividing the thickness of the tin layer 3b by the thickness of the copper layer 3a is 0.1-50.

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.

Provided is an Al alloy reflective film which does not require a protective film in that it has excellent alkali resistance (resistance to alkali corrosion), acid resistance (resistance to acid corrosion) and humidity resistance (resistance to a high-temperature, humid environment) even if there is no protective film, and which contains 2.5 to 20 at % of at least one element selected from Gd, La, Y, Sc, Tb, Lu, Pr, Nd, Pm, Ce, Dy, Ho, Er, and Tm, with the balance being Al and inevitable impurities. Also provided are an automobile light, illuminator, and ornamentation having such an Al alloy reflective film. Further provided is an Al alloy sputtering target, which is for forming such an Al alloy reflective film and which contains 2.5 to 35 at % of at least one element selected from Gd, La, Y, Sc, Tb, Lu, Pr, Nd, Pm, Ce, Dy, Ho, Er, and Tm, with the balance being Al and inevitable impurities.
摘要:
An inexpensive block polymer which is effectively available in various uses with regard to hot-melt resin compositions, pressure sensitive adhesives, carriers for pressure sensitive adhesives, and the like. This block polymer has a structure including a polyvalent mercaptan segment at its center from which two or more polymer segments are radially extended. The number-average molecular weight of this polymer is in a range of 2,000 to 1,000,000, and the two or more polymer segments have two or more different compositions. This block polymer is obtainable by a process including two or more steps of radical polymerization of polymerizable monomer components having different compositions using a polyvalent mercaptan as a polymerization initiator.

When a first communication part of an application program management part receives, from an application, an access request requesting use of a protected resource, an authentication information acquisition part acquires authentication information employed for verification of a legitimacy of the application program management part, from an authentication information storage part. A second communication part transmits the access request from the application and the authentication information, to an authentication part that determines whether or not the application is permitted to use the protected resource.
