    • A new class of photographic developing agents of the p-aminophenol type are compounds of the formula: ##EQU1## wherein R.sup.1 is an alkyl group of 1 to 12 carbon atoms;R.sup.2 is an alkyl group of 1 to 12 carbon atoms or a sulfoalkyl group of 1 to 12 carbon atoms,R.sup.3 is a hydrogen atom or an alkyl group of 1 to 12 carbon atoms,R.sup.4 is a hydrogen atom or an alkyl group of 1 to 12 carbon atoms, and X.sup.- is an anion with the proviso that when R.sup.2 is a sulfoalkyl group then X.sup.- is the sulfo radical of R.sup.2.These compounds are useful as color developing agents, especially in diffusion transfer processes, and have been found to provide advantageous characteristics as compared with conventional developers of the p-amino-phenol type, for example, a substantial decrease in the formation of unwanted color stain in the receiving layer employed in diffusion transfer processes.

    • Aqueous polymer dispersions are prepared from salts of vinyl sulphonic acid with organic nitrogen bases. The salts have the formula where R1 is a monovalent hydrocarbon radical which may be substituted by halogen or a hydroxyl group or acylated hydroxyl group or may contain ether linkages; R2, R3, and R4 may be as R1 or may be hydrogen; R4 may be a hydrocarbon radical substituted by a group of formula R1 and R2 may be polymethylene groups which connect the nitrogen atom of formula I with a group of formula the substituents R5, R6 and R7 being hydrogen, hydrocarbon radicals or hydroxyalkyl radicals, and A(-) an anion, particularly that of vinyl sulphonic acid; R2 and R3 may form a 5 to 7 membered heterocyclic ring with the nitrogen atom of formula I; and R1, R2 and R3 may be components of a 5 or 6 membered ring containing the nitrogen atom of formula I. In Examples A to E aqueous dispersions of copolymers are prepared from:-trimethyl-phenyl-ammonium vinyl sulphonate and n-butyl acrylate; trimethyl-cyclohexyl-ammonium vinyl sulphonate, vinyl acetate and n-butyl acrylate; methyl-triethanol-ammonium-vinyl sulphonate, vinyl propionate and n-butyl acrylate; a salt derived from vinyl sulphonic acid methyl ester and the reaction product of 1 mol. of diethylamine with 4 mols. of ethylene oxide, ethyl acrylate and vinylidene chloride; diethyl ammonium vinyl sulphonate, ethyl acrylate and acrylic acid; potassium persulphate is used to initiate the copolymerization.ALSO:The invention comprises salts of vinyl sulphonic acid with organic nitrogen bases. The salts have the formula where R1 is a monovalent hydrocarbon radical which may be substituted by halogen or a hydroxyl group or acylated hydroxyl group or may contain ether linkages; R2, R3, and R4 may be as R1 or may be hydrogen; R4 may be a hydrocarbon radical substituted by a group of formula R1 and R2 may be polymethylene groups which connect the nitrogen atom of formula I with a group of formula R5, R6 and R7 being hydrogen, hydrocarbon radicals or hydroxyalkyl radicals, and A(-) an anion, particularly that of vinyl sulphonic acid; R2 and R3 may form a 5 to 7 membered heterocyclic ring with the nitrogen atom of formula I; and R1, R2 and R3 may be components of a 5 or 6 membered ring containing the nitrogen atom of formula I. The salts may be prepared by neutralizing the nitrogen base with vinyl sulphonic acids; or by reacting the nitrogen base with a vinyl sulphonic acid ester, the hydrocarbon radical of the alcoholic component of the ester being transferred to the nitrogen atom. In examples there are prepared salts including N-methyl-8-hydroxyquinolinium vinyl sulphonate, ethyl-dimethylanilinium vinyl sulphonate, salts from ethyl and butyl esters of vinyl sulphonic acid and 4,41-bis-(dimethylamino-diphenyl)methane, trimethylcyclohexylammoniumvinyl sulphonate, salt of dimethyl palm kernel fatty amine, N-methyl-pyridinium vinyl sulphonate, N-methyl-quinolinium vinyl sulphonate, Nmethyl-vinylimidazolium vinyl sulphonate, Nmethyl-g -picolinium p vinyl sulphonate, Nmethyl-quinaldinium vinyl sulphonate; salts of vinyl sulphonic acid and pyridine, crotylamine, 4-isopropyl-aniline, a -naphthylamine, 4-methoxy-N,N- dimethylaniline, 1-hydroxy2-amino-propane, piperazine, N-methyl pyrrole, pyrazole, thiazole, oxazole, morpholine, thiomorpholine, hexamethylene imine, diphenylamine, N- methylpyrrolidine, methyl oxazolidine, alkoxyamines, alkanolamines, reaction products of alkylene oxides with amines; and salts from simple amines and diamines.
