    摘要: NOVEL POLYMETHINE DYES DERIVED FROM CERTAIN URAZOLE COMPOUNDS ARE DESCRIBED. THE DYES HAVE UTILITY AS FILTER DYES AND MANY OF THEM ARE USEFUL AS SPECTRAL SENSITIZERS FOR PHOTOGRAPHIC SILVER HALIDE EMULSIONS. ANHYDRO-1-(2(2-BENZOTHIAZOLYL ETHOHYDROXIDE) VINYL)-4-PHENYLURAZOLE, ANHYDRO-1-(4-(2-BENZOTHIAZOLYL ETHOHYDROXIDE)1,3-BUTADIENYL)-4-PHENYLURAZOLE AND ANHYDRO - 1 - (2-(2BENZOTHIAZOLYL ETHOHYDROXIDE)VINYL) - 4 - PHENYLDITHIOURAZOLE, FOR EXAMPLE, ARE ILLUSTRATIVE OF THE POLYMETHINE DYE COMPOUNDS.

    摘要: Novel cyanine dyes are provided which comprise first and second five- to six-membered nitrogen containing heterocyclic nuclei joined by a methine linkage; the first of said nuclei being a 2arylimino (or alkylimino)-4-aryl (or alkyl)-3-thiazoline nucleus joined at the five-carbon atom thereof to said linkage; and said second nucleus being joined at a carbon thereof to said linkage, to complete said cyanine dye.
