| Zusammenfassung: | The present invention relates to dyes and optical recording elements generally and DVD optical recording elements in particular.
Metallized azo thioether dyes having an azo group linking a substituted 3-hydroxypyridine nucleus to a phenyl nucleus are disclosed. The phenyl nucleus has an thioether substituent ortho to the azo group but does not have electron withdrawing substituents on the phenyl nucleus. The dyes are useful in optical recording elements. |
