摘要： A photographically useful alkynyl compound is disclosed which is nonionic under aqueous alkaline photographic processing conditions. The alkynyl compound is comprised of an alkynyl group attached to a methylene group through a divalent chalcogen or an imino group. The methylene group is activated by an electron withdrawing substituent. The alkynyl compounds are useful in direct positive internal latent image forming emulsions as nucleating agents and in negative working surface latent image emulsions to increase speed and/or contrast.

摘要： High-speed direct positive silver halide emulsions characterized by improved densities and highlights are prepared containing a combination of a strong inorganic chemical fogging agent and an organic reducing agent and/or its oxidized form taken from the group consisting of methyl-p-aminophenol (metol), hydroquinone, quinone, quinhydrone, 1,4-naphthalenediol and 1,5naphthalenediol, and an alkali metal sulfite, said combination being in an inert environment where it is unable to cause the formation of chemical fog centers or sensitivity centers on the silver halide grain surfaces before exposure and processing. Such an environment can be established by adjusting the pH range between 4.9 and 6.5.

摘要： Reactive cyclammonium quaternary salts including a dihydroaromatic ring nucleus, a dihydropyridinium nucleus for example, are useful nucleating agents in direct positive photographic emulsions. The salts include such compounds as a 1,2-dihydro-3-methyl-4-phenylprido( 2,1-b)-5-phenylbenzoxazolium salt. They are conveniently prepared by reacting an appropriate cyclammonium precursor compound in an organic solvent medium for a time sufficient to form the dihydroaromatic derivative.
