| titleOfInvention | Aqueous metal salt of p-phenylenediamine free base color developing agent and method for producing the same |
| abstract | The stabilized solution of the alkali metal or alkaline earth metal salt of N-ethyl-N-2- (methanesulfonylaminoethyl) -2-methyl-p-phenylenediamine is about 10-40% by weight of N -Ethyl-N-2- (methanesulfonylaminoethyl) -2-methyl-p-phenylenediamine alkali metal or alkaline earth metal salt, about 30-70% by weight of at least one of N-ethyl- A photographically inert, water-miscible or water-soluble hydroxy-containing organic solvent of an alkali metal salt or an alkaline earth metal salt of N-2- (methanesulfonylaminoethyl) -2-methyl-p-phenylenediamine; About 40% by weight of water and about 1-40% by weight of N-ethyl-N-2- (methanesulfonylaminoethyl) -2-methyl-p-phenylenediamine Preservatives for metal or alkaline earth metal salts (where wt% is based on the total weight of the stabilized solution) containing. Another aspect of the present invention is a method for preparing a stabilized p-phenylenediamine color developing solution. In another embodiment, about 10-40% by weight of an alkali metal or alkaline earth metal salt of N-ethyl-N-2- (methanesulfonylaminoethyl) -2-methyl-p-phenylenediamine, about 20 to 40% by weight. 88% by weight of water and about 1 to 40% by weight of an alkali metal or alkaline earth metal salt of N-ethyl-N-2- (methanesulfonylaminoethyl) -2-methyl-p-phenylenediamine. An alkali metal salt or alkaline earth of N-ethyl-N-2- (methanesulfonylaminoethyl) -2-methyl-p-phenylenediamine with a stabilizer (where% by weight is based on the total weight of the composition) It is a stabilized aqueous solution of a metal salt. Another aspect of the present invention is a method for preparing a stabilized p-phenylenediamine color developing solution. |
