Definitions
- the invention relates to an improved process for developing color photographic materials by using after color development a bath containing black-white developers.
- Suitable developers of the p-aminophenol series are the following:
- the after-treatment bath to be used according to the invention contains, apart from the black-white developer,
- Antioxidants such as hydroxylamine l4 Alkali metal sulfites 2-10 Sequestering agents such as sodium hexameta phosphate 1-5 Stabilizers such as potassium bromide 0.2-0.5 Alkalizing agents such as sodium or potassium carbonate, alkali metal phosphates or borates, alkali metal hydroxides or the like 1 0-20 Water up to 1 l.
- Sequestering agents such as sodium hexameta phosphate 1-5
- Stabilizers such as potassium bromide 0.2-0.5
- Alkalizing agents such as sodium or potassium carbonate, alkali metal phosphates or borates, alkali metal hydroxides or the like 1 0-20 Water up to 1 l.
- the after-treatment bath according to the invention preferably has a pH of between 8 and 12 and in particular between 9- and 10.
- the color developers to be used in the process according to the invention have the usual composition.
- color developers it is preferred to use developers of the p-phenylene diamine type.
- the color developer may also contain development accelerators such as quaternary ammonium salts, polyethyleneoxides or derivatives such as spirocyclic phosphoric esters of polyethyleneglycol. Black-white developer compounds may be added to the color developer.

Processing Method D Processmg Method B The same as method A but Without the short stop bath. Color developer as under Adevelopment time 10 min- 5 The results of the sensitometric test are shown in the utes. following table:
- Color developer as under Adevelopment time 10 minimprovement according to Which the Color developed utes.
- color-photographic negative material has its sensitivity increased and its image grain size reduced by treating it After treatment at according t0 the lhveht10htreat' 30 after the color developing bath and before bleaching with ment time4minutes: an aqueous alkaline bath containing 0.01-1 g. per liter Borax-15 g. of a black-white developer of the p-aminophenol or 1- KBr0.5 g. phenylpyrazolidone series.
