The dampening water composition is characterized in that it contains at least one kind of chemical compound represented by formula and a polyvinyl pyrolidone. R<1>O-(-CH2CH(CH3)-O-)m-H-(I) (In the formula, R<1> is a 3-8C alkyl group and m is an integer of 1-3).
Description
The invention relates to lithography damping constituent, particularly, is the damping constituent that uses about in the offset printing method of lithographic plate.
Lithography is a kind of very ingenious water and oily mode of printing of immiscible character in essence of utilizing, printing surface repels the zone of printing ink and repels water and the zone of accepting printing ink constitutes by accepting water, the former is a non-image areas, and the latter is an image-region.
Make non-image areas wetting with dumping processing solution, enlarge interfacial chemistry poor of image-region and non-image areas, can finish the repellency of the printing ink that increases non-image areas and image-region printing ink be subjected to capacitive.
The dumping processing solution of called optical imaging had the aqueous solution of the alkali metal salts or ammonium salt, phosphoric acid or the phosphoric acid salt that have added dichromic acid, for example ammonium salt, kordofan gum, carboxymethyl cellulose colloidal materials such as (CMC) in the past.
But, only contain the dumping processing solution of these compounds, have the even moistening defective of non-image part that is difficult to make version, produce thus printed matter often dirty, regulate dumping processing solution and need problems such as suitable masterful technique.
In order to eliminate these defectives, people have proposed a solution.Be about to add the Da Gelun damping mode of the aqueous solution of 20-25% Virahol as dumping processing solution.After adopting this mode, moistening the obtaining of non-image part improved, only need to get final product with very a spot of dumping processing solution, the balance adjustment of the supply of printing-ink and water is also than being easier to, the emulsification quantitative change of dumping processing solution in printing-ink is few, and printing-ink also is improved etc. to the transfer performance of shell, all has many advantages aspect the precision of operation and resulting printed matter.
But,, therefore need a kind of special device to make the isopropyl alcohol concentration of dumping processing solution keep certain, thereby cause the increasing of cost because this Virahol evaporates easily.In addition,, therefore aspect toxicity, also exist problem, not quite be fit to the requirement of operating environment because Virahol has its distinctive stench.In addition, even this dumping processing solution that has added Virahol is applied in the offset printing that makes the water rod, because on the roller and Virahol evaporation on the space of a whole page, so can not bring into play problem such as its effect.
And, in recent years, to be concerned about very highly for the society of industry public hazards, the discharge restriction of the chromium ion in the waste water becomes strict, and the use of organic solvent such as Virahol has inclining of being restricted to ask aspect safety and sanitation.
Therefore, people press for a kind of aspect environmental health safety, in presswork, do not need special training, the adjusting of its feed rate is carried out easily, and not only can prevent the dirty of press plate, and can be fit to high speed printing, can obtain the dumping processing solution constituent that the lithography of high-quality printed matter is used.
Purpose of the present invention will provide a kind of can substitute Virahol system, the comfortable and safety of operating environment, the dumping processing solution constituent of printing good stability.And provide a kind of little at dynamic surface tension, under the member condition of high speed rotating, can bring into play good and stable printing adaptability, and for various printing ink, the printing adaptability that playing stably property is good can access the lithography dumping processing solution constituent of good printed matter.
In order to finish above-mentioned purpose, the present inventor has carried out unremitting research for lithography with the dumping processing solution constituent, found that, by compound and the polyvinylpyrrolidone shown in the following formula I is used in combination, can obtain good dumping processing solution constituent, thereby finish the present invention.
Therefore, the present invention contains at least a compound shown in the following general formula and polyvinylpyrrolidone is the lithography dumping processing solution constituent of feature.

Observe (after printing 10,000) on the 1st, (after printing 20,000) on the 2nd, (after printing 30,000) on the 3rd to dirty (whether can form even clean water film on the roller) on the damping roller.
Zero ... almost do not have dirty
△ ... can see dirty a little
* ... dirty
(c) bleeding
Running with printing press when printing 5,000 and 10,000 stops, the printing ink of check image part
Be penetrated into the degree of non-image part.
Zero ... almost not infiltration
△ ... some infiltrations are arranged
* ... permeate more
(d) metallic pigment ink, UV ink printing stability
The printing ink that uses: goddess's printing ink (Co., Ltd.) bronze ink (blue or green mouthful), pink (UV printing ink) eastern magnificent pigment (Co., Ltd.)
Zero ... still fine when printing 5,000
△ ... printing ink (1 space of a whole page is cleaned midway) is arranged on shell
* ... printing ink dirty (midway, the space of a whole page and shell are cleaned for 2 times) is arranged when 1,000 left and right sides of printing
One: can't test
As can be seen, dumping processing solution constituent of the present invention, all good on any one test event, can obtain good printed matter, and dumping processing solution adaptability is also fine.
