Abstract

1,079,936. Optically sensitized emulsions. EASTMAN KODAK CO. Nov.19, 1964 [Nov.19, 1963], No.47107/64. Heading G2C. An optically-sensitized photographic silver halide emulsion contains a desensitizing amount of methylene blue, and a 5-(dialkoxyphenyl)- tetrazole wherein each alkoxy group contains up to 6 carbon atoms. The emulsion may contain a tanning developer e. g. 4-phenyl catechol and if desired a non tanning developer and is preferably unhardened. The material is particularly useful for the colloid transfer process.
