摘要： There is disclosed a recordable optical element that includes a metallized dye. The element has a transparent substrate and on the surface of the substrate, a dye containing recording layer and a light reflecting layer. The improvement is that the dye is a metal complex of a tridentate azo dye ligand containing, on one side of the azo linkage, an aminohydroxypyridine group and on the other side, an aromatic ring including an electron withdrawing substituent. The dyes that are used in the element are very light stable.
