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:
TRINUCLEAR COMPLEX MEROCYANINE DYES DERIVED FROM 2MIDAZOLIN-4-ONES, 2-IMIDAZOLIN-4-THIONES AND 2-IMIDAZOLIN4-SELENONES ARE USED ADVANTAGEOUSLY AS SPECTRAL SENSITIZING DYES IN PHOTOGRAPHIC IMAGE-FORMING MATERIALS.
摘要:
NOVEL PHOTOGRAPHIC MATERIALS COMPRISING A LIGHT-SENSITIVE LAYER AND A LIGHT-ABSORBING MATERIAL ARE DESCRIBED. THE LIGHT-ABSORBING MATERIALS COMPRISE COLORED COMPONENTS WHICH ARE DECOLORIZED BY VARIOUS FORMS OF ENERGY, SUCH AS, FOR EXAMPLE HEAT. THE NOVEL LIGHT-ABSORBING MATERIALS ARE USEFUL IN ANTIHALATION LAYERS PARTICULARLY ADAPTED FOR PHOTOTOGRAPHIC ELEMENTS DESIGNED FOR DEVELOPMENT WITH HEAT.
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.
