<P>PROBLEM TO BE SOLVED: To provide an Ag alloy reflective layer for an optical information recording medium having excellent environmental resistance, an optical information recording medium, and the like. <P>SOLUTION: This Ag alloy reflective layer for an optical information includes 0.1 to 5 atm.% in total of at least one element selected from W, Ti, V, Mn, Zr, Cr, and Ni, 0.005 to 1 atm.% of Bi, and the residue of Ag and inevitable impurities. As a consequence, this Al alloy reflective layer has improved environmental resistance including the light resistance for the light beam of specific wavelength and resistance to moist heat under specific conditions. <P>COPYRIGHT: (C)2008,JPO&INPIT |
