Description
Technical field
The present invention relates to a kind of developer solution that is used for photo-polymerization type lithographic printing plate, be specifically related to a kind of developer solution that is used for photo-polymerization type CTP (CTP) lithographic plate development treatment.
Technical background
The purpose that photo-polymerization type lithographic printing plate develops is: plate is after the exposure of suitable (laser) light source; Immerse in the specific developer solution; The light sensitive layer of unexposed portion is removed; The dummy plate base that exposes possess hydrophilic property does not then make it sustain damage to the exposure image zone as much as possible, thereby forms the camegraph of oil loving slight convexity.There is dissolution velocity in developing process based on photo-polymerization type lithographic printing plate exposure area and unexposed area after exposure in developer solution difference, promptly the dissolution velocity of unexposed area in alkaline-based developer is much larger than the exposure area.Immerse the plate in the developer solution liquid, under the friction of develop brush or sponge, unexposed coating enters into developer solution in a large number.If use single surfactant, the blank local cleaning of edition base is unclean, like this, can go up dirty when machine prints on the plate.Last dirty in, a large amount of dissolvings coating down can form insoluble matter, i.e. sediment because of the dispersibility of developer solution deficiency in developing trough.This sediment can be eliminated the dummy plate base absorption of coating, thereby makes forme dirty on when printing.Simultaneously also can in developing trough, stop up the developing trough circulation system, cause the developing machine fault.
Summary of the invention
The objective of the invention is to solve the above-mentioned technical matters that exists in the prior art, a kind of developer solution that is applicable to photo-polymerization type lithographic printing plate is provided.
For realizing the foregoing invention purpose, the technical scheme that the present invention adopts is following:
The developer solution that is applicable to photo-polymerization type lithographic printing plate of the present invention; Mainly by alkali compounds, buffer system, surfactant and solvent composition, the composite surface reactive systems that described surfactant is made up of anionic surfactant, amphoteric surfactant and non-ionic surfactant.
The percentage composition that contained composite surface reactive systems general assembly (TW) accounts for the developer solution general assembly (TW) is 3% ~ 7%.If described surfactant general assembly (TW) is lower than 3.0% of developer solution general assembly (TW) percentage composition, then the removal of plate unexposed portion is unclean, promptly keeps on file, goes up dirty during printing easily; If described surfactant general assembly (TW) is higher than 7.0% of developer solution general assembly (TW) percentage composition, then plate exposure image zone sustains damage.
The consumption of described anionic surfactant, amphoteric surfactant and non-ionic surfactant accounts for 67-79%, 14-33% and the 2-7% of composite surface reactive systems gross mass respectively.
Said anionic surfactant comprises sulphonate, higher alcohol sulfate salt and fat alkane carboxylate.
Said anionic surfactant comprises the sodium salt of dodecyl benzene sulfonate, the sodium salt of butyl naphthalene sulfonate, naphthalene disulfonate, m-nitrobenzene sodium sulfonate; Dodecanol sulfuric ester sodium salt, octanol sulfuric ester sodium salt and sodium oleate.
Said suitable anionic surfactant comprises alkyl aryl sulfonate, like the sodium salt of dodecyl benzene sulfonate, the sodium salt of butyl naphthalene sulfonate, the sodium salt of dinaphthalene disulfonate and the sodium salt of m-nitrobenzene sulfonate; Higher alcohol sulfate salt is received like the sodium salt of dodecanol sulfuric ester, the sodium salt and the oleic acid of octanol sulfuric ester.These anionic surfactants can be used alone or in combination.Preferred especially Sulfonates.
Described amphoteric surfactant is aminocarboxylic acids or sulfaminic acid class surfactant, the maximum characteristics of this surfactant be no matter in acid, neutrality or alkaline solution dissolubility all good, therefore when isoelectric point, can not produce deposition yet.
Said suitable ionic surfactant pack is drawn together in polyox-yethylene-polyoxypropylene block copolymer, APES, naphthyl phenol polyethenoxy ether, senior fatty polyoxyethylene ether, polyoxyethylene carboxylate, the polyoxyethylene sorbitan monolaurate and can be used alone or in combination.These non-ionic surfactants can be used alone or in combination.Preferred especially polyoxyethylene polyoxypropylene block copolymer, APES, naphthyl phenol polyethenoxy ether.Ionization does not take place in non-ionic surfactant in water; Be to be the hydrophilic group group with hydroxyl or ehter bond; Because a little less than the water wettability of hydroxyl or ehter bond; Therefore must contain a plurality of such groups in the molecule and just can show certain water wettability, this is to differ widely with having only the anionic surfactant of a hydrophilic radical.Non-ionic surfactant has characteristics non-ionizing in water just, has determined it superior than ionic surfactant in some aspects.As in water, with organic solvent dissolubility preferably being arranged, stability is high in solution, does not allow to be subject to the influence of strong electrolyte.The surfactant compatibility of it and other type is good, and non-ionic surfactant has good stability in hard water, and in developing process, has certain froth breaking effect.
Described detergent and sequestrant are disodium edta and gluconic acid sodium salt.
The degree that the weight of described alkali compounds accounts for the developer solution general assembly (TW) is 0.1% ~ 2.0%.Comprise inorganic base such as potassium hydroxide, NaOH, potassium silicate and sodium silicate; Organic base such as diethanolamine, triethanolamine, triethylamine and monoethanolamine can be used alone or in combination.Between the pH value preferred 11.8 ~ 12.5.
Described solvent can be phenmethylol, ethylene glycol phenyl ether, propylene glycol phenylate.Weight of solvent accounts for 0.5% ~ 0.7% of developer solution general assembly (TW).
Described damping fluid can select for use sulfosalicylic acid (PKa:11.7), this type of weak acid highly basic of phosphoric acid (PKa:12.4) to form.
Described development host adopts deionized water.After it adds a certain proportion of alkaline matter, under the stirring, add other material more successively, stirred one hour.
In order to ensure the stability of developer solution in automatic flushing process, control the concentration particular importance of various components in developer solution.Therefore, often make-up solution (promptly replenishing liquid) is joined in the developer solution.Because photographic layer is acid, need suitably to improve alkali content so replenish liquid, surfactant consumption is little, and consumption is constant in replenishing liquid.In dashing the version process, increase along with what developer solution contacted with Carbon Dioxide in Air, performance decays gradually, and is stable for making developer solution, in replenishing liquid, improves buffer usage.The pH value that replenishes liquid is preferably greater than more than 12.6 at least greater than 12.
According to foregoing invention, the photo-polymerization type surface printing plate after overexposure is immersed in the developing trough, the non-image areas of coating is taked mechanical type friction (for example through hairbrush in the developing trough or sponge), in this specific developer solution, remove.
In dashing the version process, can in continuous or a spot of developer solution that joins in the developing trough, be the concentration adjustment of developer solution the substantially constant level by certain amount with replenishing liquid.
Because the present invention adopted above technical scheme, therefore developer solution provided by the present invention overcomes the defective that high alkalinity and a kind of surfactant of single use exist in developer solution, can effectively solve in the developing process sediment problem in the developing trough.
The developer solution that is used for photo-polymerization type lithographic printing plate of the present invention; Mainly by alkali compounds, buffer system, surfactant and solvent composition; Because of adopting, it contains the composite surface reactive systems of forming by anionic surfactant, amphoteric surfactant and non-ionic surfactant; Advantages such as solved the scattering problem of development sediment preferably, it is big to have the development tolerance simultaneously, and the image areas damage is little.
