Definitions
- the present invention relates to cyanine dye salts and merocyanine dyes, and to silver halide photographic emulsions and elements which contain such dyes.
- Silver halide compounds in themselves are substantially insensitive to all but the shortest wavelengths of visible light.
- the sensitivity of silver halide emulsions has been extended to longer wavelengths by incorporation into such emulsions of various sensitizing dyes such as those of the cyanine and merocyanine classes.
- sensitizing dyes such as those of the cyanine and merocyanine classes.
- Such dyes are now routinely used in silver halide emulsions for both black and white and color photography.
- a photographic element useful for color photography may contain silver halide emulsion layers which have been sensitized respectively to red, green, and blue light.
- Sensitizing dyes utilized in color photography must accordingly exhibit the required sensitization characteristics, and in addition such dyes must be substantially completely removable from photographic elements during processing so as to impart the least possible sensitizing dye coloration to the final colored image.

13 Claims, N0 Drawings CY ANINE DYE SALTS, MEROCYANINE DYES, AND THEIR USE IN SILVER HALIDE PHOTOGRAPHIC EMULSIONS This is a continuation of application Ser. No. 3,202, filed Jan. 15, 1970, now abandoned.
The present invention relates to cyanine dye salts and merocyanine dyes, and to silver halide photographic emulsions and elements which contain such dyes.
Silver halide compounds in themselves are substantially insensitive to all but the shortest wavelengths of visible light. The sensitivity of silver halide emulsions has been extended to longer wavelengths by incorporation into such emulsions of various sensitizing dyes such as those of the cyanine and merocyanine classes. Such dyes are now routinely used in silver halide emulsions for both black and white and color photography. For example, a photographic element useful for color photography may contain silver halide emulsion layers which have been sensitized respectively to red, green, and blue light. Sensitizing dyes utilized in color photography must accordingly exhibit the required sensitization characteristics, and in addition such dyes must be substantially completely removable from photographic elements during processing so as to impart the least possible sensitizing dye coloration to the final colored image. A summary of sensitizing dye technology and examples of various sensitizing dyesmay be found in Nees and James, The Theory of the Photographic Process, Third Edition, the MacMillan Company, New York, 1966, Chapter 11.
Briefly, the present invention .relates to cyanine dye salts which contain at least two heterocyclic nuclei joined by means of a methine radical or bridge, and to merocyanine dyes.

For example, the cyanine dye salts of the present invention may be prepared by condensing a compound of formula (3) with a quaternary salt of the formula I (5) R3I I=(=CHCH=) ID] e) wherein R Z, and X are as defined above, and D represents an alkylmercapto group, a B-arylaminovinyl group, a B-arylmercapto group, a B-arylmercaptovinyl group, a B-acetanilidovinyl group or B-p-toluene sulfoanilido group.
