Novel chalcogen heterocycles, processes for their preparation, and articles containing such heterocycles |
| abstract |
Isotellurazolo[1,5-a]tellurazoles are disclosed. These heterocycles can be prepared by reacting a diarylformamidine with an aromatic tellurazolium salt which is substituted at its 2 ring position with a methine group precursor. The product heterocycles are useful directly for their blue light absorption and in forming stable heterocyclic nuclei containing compounds, such as photographic addenda. |
