Description
Technical field
The present invention relates to photosensitive material post-processing processing technique field, it is specifically a kind of colour paper carry out development plus
The colour developing solution of working hour recyclable regenerative.
Background technique
Autochromy system is that the photosensitive material containing silver chlorate colour coupler is colored by colour development generation by exposure
Image.Color developer makes the silver chlorate of exposure be converted into metallic silver.Its oxidation product is generated with Huang, product, cyan colour coupler respectively
Dyestuff, and release metallic silver and chloride ion.
Metallic silver can damage the tone of dye image, it is necessary to remove these silver.It is aobvious that metallic silver, which is transformed into silver ion,
The back reaction of shadow process.This back reaction is completed by the bleaching agent in bleach-fixing liquid, and the compound of more carboxyl iron can be used
Fe EDTA is as bleaching agent, it is the oxidant of metallic silver, and metallic silver is oxidized to silver chlorate by it.Ethylenediamine tetraacetic
Acetic acid molysite ferric iron is reduced Fe EDTA ferrous iron.
And then Fe EDTA ferrous iron passes through in conjunction with the oxygen in air after completing bleaching process
It is reduced into Fe EDTA ferric iron:
Thus reciprocal, circulation carries out.
Unexposed silver chlorate still remains after colour paper passes through colour development.It needs to dissolve these silver chlorates and go
It removes, this process is exactly fixing.This technology uses fast fixing agent thiosulfate.It is fixed reagentia process:
A certain amount of thiosulfate is consumed, in fixing in order to make thiosulfate amount is constant must add centainly
The thiosulfate of amount maintains to balance.
In colour paper process, humidity strip constantly takes a large amount of developer solutions in bleach-fixing liquid to, since developer solution is alkali
Property solution, flushing process constantly consume the acid in bleach-fixing liquid.In order to maintain the acidity of bleach-fixing liquid, keep pH value constant, it is necessary to add
Add a certain amount of acid to maintain to balance.
Chloride ion is a kind of development restrainer, usually to add in developer solution villaumite such as sodium chloride or with generate chlorine from
Son, its effect are to inhibit the formation of developer fog.The villaumite manually added is replaced using the chloride ion generated in developing process,
Chloride ion quantity is set to have reached an equilibrium state.Washing processing is carried out after colour paper exposure, printing paper enters colour developing solution
In, the principal component developer hair in the silver ion and developer solution that the silver chlorate contained in emulsion figure layer on paper is generated by exposure
Raw reaction, makes developer be changed into semiquinone imines ion:
Under the alkaline condition of developer solution, semiquinone imines ion becomes semiquinone free radical after losing a hydrogen atom:
Later, still under the alkaline condition of developer solution, semiquinone free radical is had an effect with another silver ion again, is converted to
Quinondiimine:
Quinondiimine and half quinondiimine can be with tautomerizations:
Colour coupler in colour paper coating is also dissociated in the case where the alkalinity of developer solution is adjusted, and produces anion:
Colour coupler anion is reacted with half positively charged quinondiimine with connecing, and generates leuco dye:
And leuco dye is reacted with the tautomer quinondiimine of another half quinondiimine again, has ultimately generated dye
Material
The dyestuff thus generated is the substrate for constituting color image.
Existing colour developing solution, inhibition is bad, and inoxidizability is poor, old liquid can not recycling and reusing, waste of resource, and
The discharge of development waste liquid will cause pollution to environment.Therefore, for this status, there is an urgent need to develop a kind of recyclable regeneratives
Colour developing solution, to overcome the shortcomings of in currently practical application.

It include water, protective agent and color developer between~6；The PH of C portion concentrate includes water, development accelaration between 12~13
Agent and water softener；A, B and C three parts are added sequentially to be diluted again in water and make up a prescription.
As a further solution of the present invention: the solvent in the part A is triethanolamine, and fluorescent whitening agent is s-triazine
Derivative species brightening agent, surfactant are the polymer of phenol and ethylene oxide.
As a further solution of the present invention: the color developer in the part B is the derivative of p-phenylenediamine.
As a further solution of the present invention: the development accelerant in the C portion is hydroxide and carbonate, soft water
Agent is multi-carboxylic acid's compound.
As a further solution of the present invention: the protective agent in the A and part B is that sulphite and azanol are derivative
Object.
As a further solution of the present invention: the colour developing solution also contains aromatic.
As a further solution of the present invention: the colour developing solution is applied to RA-4 colour paper high temperature rapid processing technique
When, it is desirable that its pH value is 10~11, temperature 37.8, washing time 45 seconds.
As a further solution of the present invention: the container for containing the colour developing solution of the recyclable regenerative does encapsulation process.
Compared with prior art, the beneficial effects of the present invention are: the colour developing solution of the recyclable regenerative, has inhibition
The minimum and strong advantage of inoxidizability, the performance suitable for RA-4 colour paper high temperature rapid processing technique general extensively；It should
Developer solution functions the other components in old liquid again using the chloride ion discharged in flushing process, and it is useless to avoid development
The discharge of liquid and lead to the pollution to environment, so that various effective components in medical fluid is obtained regeneration.
