Definitions
- magenta azine dye images are of importance because of their greater brilliance and stability than the magenta quinonimine dye images obtained'in the usual fashion by coupling of a pyrazolone with the oxidation products-of a p-phenylenediamine.
- azine dye images be produced with the conventional p-phenylenediamine developers as may be seen from a reference to US. Patents 2,536,010 and 2,543,338.
- the color former which is used to produce the azine dyes is an aromatic phenol containing in the meta-position to the hydroxyl group, a sulfonyl amino group. After color forming development to produce the usual quinonimine dye, a ring closure is effected with elimination of the sulfonyl radical attached to the amino nitrogen atom.
- the color formers used are aromatic amines which contain in the meta-position to the amino group, an arylamino group or a cyano-or acylamino group.
- ring closure takes place through elimination of the substituents on the amino nitrogen atom, meta to the amino group.
- w-l r acyl such as acetyl, propionyl, butyryl, benzoyl and the like or sulfonyl such as methyl sulfonyl, ethyl sulfonyl, phenyl sulfonyland the like
- A is hydrogen, carboxyl or carbamino, i.e., -CONH or CONHR in which R is an alkyl radical as above or a sulfonated aromatic radical containingan aliphatic radical of at least five carbon atoms
- B is hydrogen, alkyl as above or an aromatic radical of the benzene series as above
- C is hydrogen, hydroxy, carboxy, alkyl as above, or an aromatic radical of the benzene series as above.
- color formers within the ambit of the above formula are the following:
- Compound 1 6-(p-methoxyphenylamino)-8-hydroxy-2-methy1cinchontuic aci 6-ethylamino-S-hydroxyquinoline All of the above compounds may be prepared by well known reactions. Typically, Compound 1 may be prepared as follows:
- the other six substituted 8-hydroxyquinolines specifically listed may be prepared by reacting the selected amine with a 6-haloquinoline in an autoclave at 150200- for 4 to 10 hours in the presence of a copper catalyst.
- n-butylamine is reacted in this way with 6-chlo1'o- 8- hydroxy-Z-phenylcinchoninic acid or p-anisidine with 6- chloro-S-hydroxy-Z-methylcinchoninic acid to yield Comat pounds 6 and 8 respectively.
- ethylamine is reacted with 6-bromo-8-hydroxyquinoline to yield Compound 9 and methylamine reacted with 6-chloro- S-hydroxycinchoninic acid toyi eld Compound 7.
- a conversion of the secondary amine to amides or sulfonarnides is effected by reaction of the amine with an appropriate carbonylchloride in the presence of an acid binding agent such as pyridine or triethylamine.
- the product is then isolated by the removal of the solvent at reduced pressure and acidification of the residue after dilution with water.
- the 4-carboxamides, as in Compound 3 are prepared by treatment of a mixture of 6-amino-2-myristoylaminotoluene-4-sulfonic acid and 6-(methylaminobenzenesulfonamide)-8-hydroxy-2-methylcinchoninic acid in pyridine solution with one-half mole of phosphorous trichloride.
- the azine dye image is produced from the originally formed quinonimine through elimination of the elements of acyl or sulfonyl from the amino group ortho to the intermediate azomethine coupled position in the quinoline nucleus and elimination of hydrogen from the benzene, ring ortho to the primary amino group originally present in the developer molecule.
- Such ring closure is schematically represented by the following equation:
- a color developing solution is prepared as follows:
- Compound 1 0.1 gram was dissolved in 5% sodium carbonate solution (5 mls.) and the solution was made up to 5 0 mls. with a portion of the aforesaid color developer solution.
- a strip of exposed positive film is agitated in this solution for 5 to 10 minutes.
- the film on which a green azomethine dye is orginally produced is bleached in ferricyauide and fixed in acid hypo. On treatment with the acid hypo, the green azomethine dye converts to a brilliant magenta azine dye.
- any of the compounds listed above may be utilized for our purpose.
- the couplers are to be employed in the emulsion, they should contain a non-difiusing group, preferably an alkyl chain of at least 1-0 carbon atoms as per Compound 3. If, on the other hand, they are to be used in the developer, they should not possess groups which render them nondifiusing in the emulsion.
