. 1 This invention pertains to v a new class of N-substituted aminoaniline derivatives. More particularly it pertains to N-alkyl-N -(sulfophenylthioalkyl) aminoanilines. These compounds are useful as photographic developing agents.
Variousi arylenediamines have; been used as photographic developing agents, but themost im-. portant of them, namely} para-phenylenediamine and its 1ower-N,-N'-dialkyl derivatives have the disadvantage that they are readily absorbed by the skin and give rise to dermatitis. Since these agents are strong photographic developers and readily couple with color formersduring the development of latent silver halide images to produce quinoneimine or azomethine dyeimages in situ with the silver images, they are used in most commercial processes ofcolor photography. The compounds, however,1due1to their toxicity constitute a-health' hazard in photographic developing laboratories.
An object of this invention is to provide a new class of photographic'developing agents. A further object is to provide a new class of photographic developing agents which are useful in chromogenic development and are free from toxic effects, The more specific object is to provide a new class of N-alkyl -N -1(sulfophenylthioal kyl)aminoanilines. Still other objects will;be apparent from the following description of the invention. a 7 I The new compounds of this invention may be represented bythe following general formula:
where R is a hydrogen atom or an alkyl or substituted alkyl group oran alkoxy or substituted alkoxy group; n isa-positive integer from 2 to 10, m is 1 or,2 and alkyl contains from 1 to 6 carbon atoms. Among the useful alkyljradicals for R there .".may ,be mentioned CH3, .-C2H5, -.CH(CH3) 2'and amongthe useful substituted alkyl' radicals R there may. be mentioned CH2OH and 'CHzCl. Suitable specific alkoxy radicals for R include OCl-l3, -OC2H5 and OCH(CH3)2. R, however, preferably is hydrogen or an unsubstituted alkyl or alkoxy radical of 1 to 3 carbon atoms.
It is important that the tertiary nitrogen atom and the sulfophenyl group in the above compounds be separated by at least two methylene (CH2) groups in order to obtain a high degree lines are used in place of the N-alkyl aniline in 3 Claims. (01. 260-510) of photographic development. The'compounds where n is 3 to 6 and alkyl contains 1 to 4 carbon atoms are preferred. When n is greater than 10 thecompounds still possess some developing properties but are less satisfactory than compounds covered by Formula I because the developer has a slow rate of diffusion into a colloid silver halide-emulsion layer and it is more difficult to wash such compounds out of the colloid silver halide emulsion layers. Y The compoundsofFormula I may be prepared by the following series of chemical reactions: (at) preparation of an N-alkyl-N-(phenylthioalkyl) aniline byreaction of an omega-halogen substituted alkyl phenylthioether containing the halogen and thioether groups on the opposite ends of;the straight chainalkylene radical with an N-alkylaniline, e. g., N-mthylanilinali-ethylaniline or N-butylaniline. v This reaction is usually carried out under neutral to'alkaline conditions; (b) preparation of N-alkyleN-( om ega-sulfophenylthioalkyl) anilines by the reaction of the tertiary amine derivative obtained in step (a) with a sulfonating agent, e. g., hot concentrated sulfuric acid; (c) preparation of the. corresponding p-nitroso-N-alkyl N (omega-sulfophenylthioalkyl) aniline by reaction of the compound obtained in step (b)' with nitrous acid; vand (:1) reduction of the nitroso compound obtained'in step" (c), e.. g., with iron or catalytically with hydrogen to the corresponding amine'having the general Formula I. v When Iii-methyl-m-toluidine, N-ethyl-m-toluidine, N-methyl-m-anisidine, N-ethyl-m-anisidine, or similarly nuclear substituted N alkyl anithe' above syntheses one obtainsthe correspondingly substituted developers. f Thisinvention will be further illustrated by the following examples. They exemplify suitable specific methods for the preparation of the compounds and illustrate their uses and properties but are not intended to limit the invention.

F. Diazomoupling, of N'-ethybNesulimphenylthio amylaniline withp-toluidine' A'diazonium: chloride solution, prepared from 8.2 grams (0.076 mol) of -p-toluidine, was added with stirring to a solution of 36 grams (0.076 mol), of the amine in '200 ml. of water containing grams of sodium hydroxide. The temperature of both solutions was below 10 C. The mixture becamedark magenta immediately but no solid separated. Aiterthe-mixture had stoodfor about .15 minutes, grams of sodium hydroxide. dissolvedin 50ml. of waterwas added and the'mixture was allowed tostandin ice for an hour longer. Some dye separated'as a visc'ous,..red, oily paste. I"his did not become crystalline iupon standing overnight inthe ice chest, so .the mixture was diluted'withfanequal volume of'water, heated to 50'and reduced with sodium-hydrosulfite until a test portion noloriger showed the presence of an azoxdye. i The yellow solutionwas filtered to remove p'toluidi'ne which had. separated and then acidified with acetic acid.l The gummy solid which separated was dissolved in dilute sodium hydroxide, the undissolved sulfur was filtered, and the solid was reprecipitated with acetic acid as a light brown powder. The process was repeated again and the solid was dried in a vacuum desiccator; weight 12.10 grams, M. P. 237 C. I
The compound is soluble to the extent of about 8.5 grams per liter, of water containing a stoichiometric amount ofsodium hydroxide. ,It is possible to prepare a developer solutioncontaining an adequate amount of the color developer by using potassium carbonate or sodiumcarbonate or other alkalies by the {aid of ,a-hydrotropic wetting agent, e. g., sodium dodecyl suliate.

By substituting equivalent amounts of ethylenechlorobromide or other polymethylene chlorobromides, e. g., tetramethylene chlorobromide, hexamethylene chlorobromide, heptamethylene chlorobromide, monomethylene chlorobromide and decamethylene chlorobromide for the trimethylene chlorobromide of Example I or the pentamethylene chlorobromide of Example II till other homologous compounds which fall under eneric Formula I above can be prepared.
Similarly by substituting for the N-ethylaniline 01' Examples I and II or in similar reactions using the chlorobromides in the preceding paragraph the other N-alkylanilines listed before the above working examples one can make still other homologous compounds which come under structural Formula I.
Among the suitable compounds which can be made as just taught are:

In the foregoing table the cyan, magenta and yellow coatings were dispersions of light-sensitive silver iodobromides in polyvinyl acetal color formers of aromatic halides of the type described in U. S. Patents 2,397,864, and 2,380,033 and U. S. applications Ser. Nos. 9,330, filed February 19, 1948, now U. S. Patent 2,513,190 and 29,921, filed May 28, 1948, now U. S. Patent 2,538,257. In the table gamma refers to the development factor and fog relates to the density of development in the unexposed portion of the photographic film. Block speed is an arbitrary figure indicating the speed of the developer. If a developer has a block speed one unit less than another, this means that the photographic film will require about twice the degree of exposure to give an image of the same density as the second under the same conditions of development. Gamma is defined in Neblette, Photography page 412 (published by D. Van Nostrand Company, 1942). Values of the block speed and/or gamma comparable or superior to those of the commercial developer, p-aminodiethyl-aniline, are important. Increases are shown in the table for certain of these values. Particularly important is the fact that the new developers cause less fog than the p-aminodiethylaniline.
The compounds when employed as photographic developing agents may be used as the free acid or as a suitable derivative of the sulamass? -fonic Zaci'd 'groupfei'g :the'ialkali-'imetalzw ammonium salt, according to the't'solubiiityreqmrements of -the system.

' V I-he ,nov'eldeveloping agents of-this invention can be admixed Withfotlier conventional constituents of photographic developers including alkaline materials; e. g.,sodium carbonate, potassium carbonate sodium hydroxide, lithium hydroxide; preservatives, e. g., lithium, sodium, potassium, and ammonium sulfites and bisulfites, amine salts of sulfurous acids, for example, trietha nolamine sulfite, morpholine sulfite, tetramethylammonium .sulfite, trimethylbenzylammonium sulfite; restrainers, e. g., sodium, potassium, and lithium chlorides, bromides and iodides, ammonium bromide; other ingredients, e. g., emulsion-hardeners, --for -exampl e,- potassium aluminum sulfate, chrome alum; bufiieiing-salts; e; -g., disodium hydrogen phosphate; sddium' metaborate, borax.

Another advantage of this'iiivention resides in the'fact that the compounds are much less-toxic or'a'llergenic in contact with human skin than paininodiethylani'line.
