Abstract
A silver halide photographic emulsion containing at least one sensitizing dye represented by the following general formula (I), ##STR1## in which Z represents an atomic group necessary for forming a benzoxazole nucleus or a naphthoxazole nucleus; R.sub.1 represents an aliphatic group; R.sub.2 represents an alkyl group, an allyl group or an aryl group; R.sub.3 represents an alkoxycarbonylalkyl group, an alkoxyalkyl group, an N-(N,N-dialkylaminoalkyl)carbamoylalkyl group, an N-(N,N,N-trialkylammoniumalkyl)carbamoylalkyl group or an N,N,N-trialkylammoniumalkyl group, with R.sub.2 being a phenyl group where R.sub.3 is an alkoxycarbonylalkyl group; X represents an acid anion; and n represents 0 or 1.
Claims14
A silver halide photographic emulsion containing at least one sensitizing dye represented by the following general formula (I):
- ##STR29## in which Z represents an atomic group necessary for forming a benzoxazole nucleus or a naphthoxazole nucleus;
- R.sub.1 represents a member selected from the group consisting of an unsubstituted alkyl group;
- an alkyl group substituted with a hydroxy group, an alkoxy group, an acyloxy group, a carboxy group, an alkoxycarbonyl group, a sulfo group, or an aryl group;
- or an allyl group;
- R.sub.2 represents an alkyl group, an allyl group or an aryl group;
- R.sub.3 represents an N-(N,N-dialkylaminoalkyl)carbamoylalkyl group, an N-(N,N-trialkylammoniumalkyl)carbamoylalkyl group or an N,N,N-trialkylammoniumalkyl group, with R.sub.2 being a phenyl group where R.sub.3 is an alkoxycarbonylalkyl group;
- X represents an acid anion;
- and n represents 0 or 1.
