Abstract

1409357 Supersensitized photographic silver halide emulsions FUJI PHOTO FILM CO Ltd 26 Oct 1973 [27 Oct 1972] 50061/73 Heading G2C Photographic silver halide emulsions are supersensitized in the red with a combination of dyes comprising (i) a carbocyamine of the formula: - wherein Z<SP>1</SP> completes a #-naphthoxazole or #- naphthoimidazole nucleus which may carry substituents, Z<SP>2</SP> completes a benzothiazole, benzoselenazole or 4:5-dihydro[ 1:2-d] thiazole nucleus which may be substituted, A<SP>1</SP> is H or an alkyl or aryl group which may be substituted, R<SP>1</SP> and R<SP>2</SP> are substituted or unsubstituted aliphatic hydrocarbon groups, at least one being hydroxyalkyl, carboxyalkyl or sulphoalkyl, (X<SP>1</SP>)# is an acid anion and I is 0 or 1, the dye forming an intramolecular salt when l is 0; together with (ii) a carbocyanine of the formula:- wherein Z<SP>3</SP> completes a benzothiazole, p-naphthothiazole, benzoselenazole or 4:5-dihydro naphtho- [1:2-d] thiazole nucleus which may be substituted, Z<SP>4</SP> completes a benzoxazole or benzimidazole nucleus which may be substituted, and A<SP>2</SP>, R<SP>3</SP> R<SP>4</SP> (X<SP>2</SP>)# and m are as defined for A<SP>1</SP>, R<SP>1</SP>, R<SP>2</SP>, (X<SP>1</SP>)# and l respectively; and/or together with (iii) a carbocyanine of the formula:- wherein Z<SP>5</SP> and Z<SP>6</SP> each complete a benzthiazole, benzoselenazole, #-naphthothiazole or p-naphthoselenazole nucleus which may be substituted and A<SP>3</SP>, R<SP>5</SP>, R<SP>6</SP>, (X<SP>3</SP>)# and n are as defined for A<SP>1</SP>, R<SP>1</SP>, R<SP>2</SP>, (X<SP>1</SP>)# and I respectively.
