    摘要： An optical recording element having a transparent substrate and on the surface of said substrate, a recording layer and a light reflecting layer. The recording layer comprises a metallized carbamoylazo dye having an azo group linking a substituted 3-hydroxypyridine nucleus to a phenyl nucleus. The phenyl nucleus has a carbamoyl substituent ortho to the azo group. The unrecorded recording layer has a refractive index, at a selected wavelength from 400 to 660 nm, comprising a real part (n) greater than 1.8 and an imaginary part (k) less than 0.2.
