Definitions
- the present invention relates to photographic developers.
- alkaline developers For the development of latent photographic images, especially in halide silver emulsions, alkaline developers have long been used.
- the alkalinity of these developers consisting of a mixture of several substances normally is due to the presence of an alkali hydroxide or an alkali carbonate.
- :n being at least 1) alsoh ave a strong alkalinity and a tendency to absorb carbon dioxide. Moreover, all of these agents which are preferable for the purpose are liquid and many have a disagreeable odor and therefore are not suitable for the production of developing commercial use.
- R1 H or aralkyl or alkyl or hydroxyalkyl or p ly ydr va y
- the hydroxyl groups may be free or etherifled or esterified; internal ethers are also useful. It is necessary that the compound should'be well soluble in water.
- Such polyhydroxyalkylamines are especially amino-derivatives of the sugars and carbohydrates having 5 and 6 carbon atoms but also lower and higher homologues may be used.
- the carbon atoms combined with the hydroxyl groups may also be separated by one or more C-atoms without a hydroxyl group.
- glucamine methyl-, ethyl-, propyl-, dodecyl-glucamine, mannamine, galactamine, lactamine, fructamine, arabinamine, xylamine, 1- or v2-aminopropane diol.
- These bodies may be used in all kinds of known developers, for example rapid developers, fine grain developers, blue and brown tint developers, negative developers, positive developers, paper developers, reversal developers, and color developers used in the color development processes.
- Photographic developer comprising develop D sodium sm'fite 60 ing agents and an aliphatic hydroxyalkylamine mctamine d0 80 containing in its molecule at least one alkyl chain Potassium bromide do 2 having at least two hydroxyl groups combined "f with difierent carbon atoms.
- Photographic-developer comprising developing agents and mannamine. I I l 7 Soft workmg 3. Photographic developer. comprising develop- Water cc 1000 ing agents and lactamine.
- Photographic developer comprising developams" 15 lng agents and methylglucamine. Dry sodium sulfite do PAUE GOLDACKER. Xylamine dn GEORGMAISER. Potassium bromide do 2 ERNST SCHMITZ-HILLEBRECHT.
