Patented Oct. 2, 1951 COLOR DEVELOPERS FOR THE PRODUC- TION OF AZINE DYE IMAGES Robert C. Gunther, Easton, Pa., assignor toGeneral Aniline & Film Corporation, New York, N; Y., a corporation of Delaware No Drawing. Application June 28, 1949, Serial No. 101,913
The present invention relates to the production of azine dye images by color forming development while employing as the color forming developer derivatives of ZA-diamino aniline in which the amino group in the 2-position is substituted by an. aliphatically linked hydrophilic group.
This application. is. a continuation-in-part of my application SeriaLNo. 793,532, filed December 23,. 1947,, now abandoned, entitled Color Developers for the Production of Phenazonium Dye;- stufilmages.
Inthe copending application Serial No. 640,382, filed on January 10, 1946, by Willy A. Schmidt and Vsevolod Tulagin, now U. S. P.. 2,486,440, there is described, the production of azine dye images by color forming development while utilizing inter alia as the color developer derivatives f, 2,4'-diamino-aniline. While these color developershave been found to be effective-inproducing the desired dyestuff images in the presence of the usual color forming componentsit is noted that they have atendency tobe. adsorbed to silver halide. grains. of the photographic emulsions, thereby making it difficult 110: efiectthe complete removal thereof from the emulsion by washing after development. Furthermore, saidv compounds have been observed-to cause stainin thereduction of silver halides, particularly when such. reduction takes place in the absenceoi a color former.
Difiiculties have also been encountered in the production of yellow dye images by the utilization of the. aforestated developers. Experience has shown that when using'such developers with color formers generally employed for the production of. yellow azomethine images, i. e., open chain;
keto methylene compounds, magenta images rather than yellow images ensue. The emagenta: images may besubsequently converted-into yellow images but only by a separate step involving a treatmentwith an alkali.
It has now been-discovered that the production of azine dye images can be effectively carried out without the aforenotedobjectionsif there be employed as color developers derivatives'of 2,4-diamino anilinesin which the amino group in the 2.-po'sition is; substituted. by an aliphatically linked hydrophilics group such: as; hydroxyj, car
boxy or sulfo. Inasmuch as said compounds are:
capableofi effecting the reduction of silver halides including; latent images without the formation of 13 Claims. (Cl. 9588) stain, they may also be employed as developers for black and White images.
These developers also havethe unique property of yielding yellow dye images directly when employed to develop a developable silver halide emulsion in the presence of an open chain keto methylene compound. They are therefore admirably suited for the production in one development step of azine dye images in the three subtractive colors.
Developers utilizing such compounds and their employment particularly in the production of azine dye images constitutethe purposes and object of the present invention.
The derivative of 2,4-diamino aniline contemplated for use herein as developers are typified by the following structural formula:
NR R
wherein R is hydrogen or alkyl, i. e., methyl, ethyl, propyl, butyl, amyl or the like and R1 is an aliphatic radical such as alkyl as above, carboxy alkyl, such as carboxy methyl, carboxy ethyl, and the like; hydroxy alkyl, such as hydroxy ethyl, hydroxypropyl, andthe like, aryl, such asphenyl, toluyl and the like; carboxy alkyl aryl, such as oarboxy methyl phenyl, carboxy ethyl phenyl, and the like, carboxy alkoxy aryl, such as carboxy methoxy phenyl, carboxy ethoxyphenyl; hydroxy alkyl aryl, such as hydroxy methyl phenyl, hydroxy ethyl phenyl, and the like; and hydroxy alkoxy aryl, such as hydroxy. methoxy phenyl, hydroxy ethoxy phenyl and the like, R2 is an alkyl group substitutedby a hydrophilic group such as carboxy alkyl, such as carboxy methyl, carboxy ethyl and the like; hydroxy alkyl, such as hydroxy ethyl, hydroxy propyl, and the like; sulfo alkyl such as, sulfomethyl, sulfoethyl, sulfop-ropyl, sulfobutyl and the like and X and Y are hydrogen, alkyl as above, sulfo orcarboxy, or together represent the atoms necessary to complete a sixmembered isocyclic ring system such as benzo and the like. It is to be observed that in the above compounds the substituent groups repre- HNGO c1110 OH N-CHzCHaOH 4- (B-hydroxyethylamino -6- (4' -carboz zy-methoxy phenylamino) metamlic acid Nil-@OCHa 4-( carbpxymethylamino) -6- (4-methoxy phenylamino metanilic acid l qHz 2- (B-sulfoethylamino) -4-phenylamino aniline NH C Hz 0 H2 0 H NHCHQOHZOH 4, G-di (B-hydroxyethylamino )-metanilic acid 2- B-hydroxyethyiamino) 4- (B-sulfoethylamino) --methyl aniline HOzS NHCHr-HOH 4 B-hydroxy-f:-methyl-ethylamino) -6-phenylaminometanilic acid 8 0 CaHs CHIOH 4- (a-di (hydroxymethyl ethylamino -6- (3'-ethoay phenylamino)-metanilic acid 9 NHCHI NHCHaCHaOH l THz 4- (B-hydroxy ethylaniino) -6-methylamino-metanilic acid moms 03H 4-(sulfomethylamino)-6-(metl1gl phenyl amino)-metanilic aci The aforementioned compounds are prepared by reacting in the proper sequence 2,4-dichloro- 5-nitro benzene sodium sulfonate with the amines desired to be introduced into the 2- and 4-positions of the benzene ring, and then effecting reduction of the nitro group to an amino group. The preparation of the compound by the aforesaid method is made possible by the fact that the chlorine atom in the 4-position is more easily replaced by an amino group than the chlorine atom in 2-position. Thus by refluxing the 2,4-dichloro-5-nitro benzene sodium sulfonate with an equivalent of an amine, the chlorine atom in 4- position is selectively replaced by such amine. By subsequently treating the resulting compound with the same or a different amine under more elevated temperatures, i. e., temperature ranging from to 150 C., the chlorine atom in Z-position is replaced by the amine.
The following is a specific illustration of the application of the foregoing general method in the production of l-(p-hydroxyethylamino) -6- phenyl amino metanilic acid.
Into a 1-liter, 3-necked round-bottom flask equipped with a mechanical stirrer and a reflux condenser was placed 147 parts of the sodium salt of 2,4-dichloro-5-nitro benzene sulfonic acid, 31 parts of ethanolamine and 54 parts of sodium carbonate dissolved in 250 parts of water. After the stirrer was started, the contents of the flask were gently refluxed for 10 hours. 200 cc. of 30% sodium chloride solution were added to the hot reaction mixture and the flask was then cooled in an ice bath. The precipitated orange solid was collected by filtration, washed with a small amount of water, and dried overnight at 80-90 C.
A glass interliner for an Aminco shaking-type bomb was charged with 95.6 parts of the 2-chlorol-(p-hydroxyethylamino)-5 nitro benzene sodium sulfonate (prepared as above), 30 parts of aniline and 34 parts of sodium carbonate dissolved in 200 parts of water. The liner was sealed in the bomb and the bomb shaken at C. for 15 hours. The bomb was cooled and the solid removed from the interliner with small amounts of hot water. .250 cc. of 30% sodium chloride solution were added with vigorous stirring of the mixture and the whole was then cooled in an ice bath for several hours. The precipitated solid was collected by filtration, washed with 50 parts of water, and then digested with 200 parts of ethanol. The product was again collected on a filter and dried overnight at 60 C. in a vacuum oven.
10 parts of 2-phenylamino-4-(fi-hydroxyethylamino) -5-nitro benzene sulfonic acid (prepared as above) were added portion-wise to a boiling solution of 40 parts of sodium hydrosulfite in 200 cc. of sodium hydroxide. After reduction is complete, a small amount of decolorizing carbon is added to the solution. The mixture is boiled vigorously for several minutes and then filtered rapidly through a fluted filter. Thecompound was then isolated from the clear filtrate as the inner salt by acidification with glacial acetic acid. The mixture was cooled in an ice bath for several hours, the inner salt collected on a filter and washed with water. The product was then dried six hours at 65 C. in a vacuum oven and constituted the 4-(B-hydroxyethylamino)-6-phenyl amino-metanili'c acid.
The same procedure may also be utilized in the preparation of the other compounds noted above while employing amines containing an aliphatically bound hydrophilic group different from that described in the above example. Such other amines are for instance B-sulfoethyl amine (taurine) m-amino-phenoxy-acetic acid, amino acetic acid, p-amino phenyl ethyl alcohol, 10- amino phenyl acetic acid, 2-amino-2-methyl- LB-propanediol and the like.
As stated, the aforementioned derivatives of 2,4-diamino aniline are characterized by their marked ability to effect reduction of silver halides, i. e., latent images, reverse images, bleached images, and the like, without formation of ob-.
jectionable stain. As a consequence of the reducing power they may be employed for development of black and white images or for the production of color images.
One of the mst notable properties of the aforementioned derivatives of 2,4-diamino aniline, however, is, as stated, their ability to directly yield yellow dyeimages. This result is achieved when employin the developers to develop a developable silver halide emulsion in the presence of an open chain keto methylene compound even though the emulsion during a, subsequent processing step be treated with an acidic bleach bath as is usual in the processing of film to azine dye images. In other words, whereas the formerly employed, ZA-diamino anilines only yielded yellow images, as the result of a subsequent alkaline 6. consequence such developers very materially contribute to the utilization on a commercial scale of the azine method for processing film in the three subtractive colors.
The yellow dyes obtained by color development with my developers appear to be true azines. Thus "they withstand treatment with an acid bisulfite whereas yellow azomethines do not. Furthermore they are not split by strong mineral acids as happens with the yellow azomethines. Such yellow dye images have excellent lightfastness and brilliance and they adequately complement the magenta and cyan dyes produced by the mine methods.
The color formers employed for producing the dye images are those used in the production of color developed images, i. e., those containing aromatic-primary amino, phenolic hydroxyl or active methylene groups.
Examples of such compounds for producing the magenta images are: 3.6-d-isulfo-8-benzsulfonylamino naphthol-1; 8-benzsulfonylaminonaphthol-1; B-hydroxy quinoline; naphthsultam acid; 3-sulfo-7-phenylaminonaphthol-l; li8- bi's- (benzsulfonyl amino)-naphthalene; 6-bromo-8- hydroxy quinoline; 6-sulfo-8-hydroxy quinoline;

Examples of cyan color formers are: 3-sulfo- 6 aminonaphthol 1; 3 sulfo-S-phenyl-aminonaphthol 1; 3-sulfo-6-(4-methoxy-phenylami no) -naphthol-l; ethyl urethane of phenyl J acid; 6 (4' octadecoxy-phenylamino) -1-naphthol-B-sulfonic acid; 3-sulfo-6-oleylamino-naphthol-l, and the like.
