Definitions
- each R is -H, --NH -NHR', -NR -SH, -SR', -OH, -OR', NO COOH, -COOR, or halogen, each R being alkyl, e.g., methyl, ethyl, butyl, and the like.
- suitable antifoggants are 1,3- diaminobenzo [f] quinazoline, l-hydroxybenzo [f] quinazoline, l-mercaptobenzo[f]quinazoline, and l-hydroxy-3- aminobenzo[f]quinazoline.
- Silver halide emulsions and elements stabilized as described can be chemically sensitized, e.g., with noble metal sensitizers alone or in combination with sulfur or selenium sensitizers. They can contain spectral sensitizers, incorporated color-forming couplers, incorporated developing agents, other antifoggants, hardeners, plasticizers, coating aids, vinyl polymers, and other suitable photographic addenda such as described in US.
