ABSTRACT:
A dye mixture is disclosed. The mixture is useful in recording layers of optical recording elements. The mixture has:
a) a real index of refraction of at least 1.8 in the 780 to 790 nm region of the spectra;
b) an imaginary index (k) between 0.3 and 0.02 in the 780 to 790 nm region of the spectra;
c) a metallized azo dye comprising an azo group linking a substituted 3-hydroxy-pyridine nucleus to a phenyl nucleus wherein the phenyl nucleus has an alkoxy or thioether substituent at its 2-position; and
d) at least a second dye.
