Definitions
- Photographic processing solutions in which a silver halide solvent is added to a developer solution have been known for more than 60 years.
- These combined developing and fixing solutions also known as a monobath, are generally prepared by combining a developer solution which contains all the conventional developer ingredients with water-soluble thiosulfate salts such as sodium thiosulfate or ammonium thiosulfate which acts as a silver halide solvent.
- Other silver halide solvents which have been proposed for a monobath solution, include potassium thiocyanate and potassium cyanide, but the latter cannot be used in practice because it is a lethal poison.
- the two processes of development and fixing proceed separately and simultaneously.
- the sensitometric properties of the final results can be influenced within certain limits depending on the kinetic characteristics of the two processes.
- N C-R1 I-IS(3 D-X N-(i-OH wherein R represents hydrogen, alkyl such as methyl, ethyl, propyl, isobutyl, butyl and the like; aryl, such as phenyl, tolyl and the like; aralkyl, such as benzyl, phen- 3,240,603 Patented Mar.
- carboxyalkyl such as carboxymethyl, carboxyethyl, carboxypropyl
- X represents, in addition to hydrogen, the grouping CH2-N wherein R and R are lower alkyl groups having the value given above for R and the group wherein Y represents the atoms necessary to complete a heterocy-clic nucleus, such as a piperidine and morpholine nucleus.
- the combined fixing and developing solution prepared with the above 2-rnercapto-o-hydroxypyrimidine derivatives are superior to the previously known monobath solutions because they remain free from silver sludge even after extended use and development of large quantities of film. Thus, the keeping qualities of the combined fixing developing solutions are noticeably improved on use.
- the combined fixing and developing solution of this invention otter the advantage of dissolving all of the undeveloped silver halide left in the emulsion layer. For this reason, our new monobaths are eminently suitable for the processing of photographic transparencies.
- the fixing developers of our invention can be used for the processing of films and paper.
- the processing time required varies somewhat with the type of photographic material and with the extent of agitation but is generally within a time limit of from two to seven minutes.
- any of the known photographic developing agents such as hydroquinone, paramethylaminophenol sulfate (Methol), 1-phenyl-3-pyrazolidone (Phenidone), 1- (p-methylaminophenyl) -3 -amino-A-2-pyrazoline, 4-aminopyrazolone and the like.
- the combined developer fixer solutions may also contain the usual developer additives including sequestering agents, such as ethylenediamine, tetracetic acid and its alkali metal salts; an alkali, such as potassium hydroxide, sodium hydroxide, sodium carbonate, potassium carbonate; an antioxidant, such as an alkali metal sulfite or bisulfite; developer accelerators, such as cetyl pyridinium bromide or thallium nitrate; antifoggants, such as potassium bromide, sodium bromide, nitrobenzimidazole; and, substances which influence the image tone and act also as restrainers such as mercaptobenzimidazole and mercaptobenzothiazole, benzotriazole and phenylmercaptotetrazole.
- sequestering agents such as ethylenediamine, tetracetic acid and its alkali metal salts
- an alkali such as potassium hydroxide, sodium hydroxide, sodium carbonate, potassium carbonate
- a thickening agent such as sodium carboxymethylcellulose, tragacanth, the copolymer of an alkyl vinyl ether and a maleic acid derivative or similar materials makes it possible to obtain fixing developers having a paste-like consistency which can be used for processing paper and film in certain developing equipment which requires the use of highly viscous processing solutions.
- PREPARATION II Z-mercapto-6-hydroxy-4-carboxymethylpyrimidine us CH 70 grams of thiourea and 202 grams of the diethyl ester of acetone dicarboxylic acid were added to a solution of 23 grams of sodium in 1 liter of absolute alcohol and the mixture heated for three hours under reflux. The alcohol was evaporated, the residue dissolved in water and weakly acidified with hydrochloric acid. An oil separated which solidified on stirring with a glass rod. The purification was carried out by recrystallizing the product from a mixture of one part of water and two parts of alcohol; M.P. 158 C.

The alcohol was distilled off and the residue recrystallized from aqueous alcohol; M.P.
- PREPARATION VII 2 mercapto-4-rnethyl-6-hydroxy-5-(N-morpholylmethylene -pyrimidine 26.1 grams of morpholine, 20.0 grams of a 30% formaldehyde solution, 1 mol of glacial acetic acid and 12.8 grams of thiouracil and 250 milliliters of alcohol were heated under reflux for five hours. The alcohol was then distilled off and the residue recrystallized from aqeous ethanol; M.P. 223 C.
- PREPARATION VIII 2 mercapto-6-hydroxy-4-phenylpyrimidine (4-phenyl- 2-thiouracil) 11s on 11.5 grams of sodium dissolved in 500 milliliters of absolute alcohol were mixed with 96 grams of ethyl" benzoylacetate and 39 grams of thiourea. The mixture: was heated under reflux for five hours. The reaction: product which had separated was dissolved in hot water, treated with charcoal and precipitated with glacial acetic acid. The compound recrystallized from glacial acetic acid; M.P. 270 to 273 C.
