た界面適性の油性インキを必要とする。(B) Prior art and its problems A lithographic printing plate consists of an oleophilic image area that accepts all oil-based ink and an oil-repellent non-image area that does not accept ink.
Generally, the non-image area is composed of a hydrophilic area that receives water. Therefore, in normal lithographic printing, both ink and water are supplied to the printing plate, and the image area selectively receives colored ink and the non-image area receives water, and the ink on the image is applied to a substrate such as paper. This is done by being transcribed. Lithographic printing plates that use dampening water include presensitized plates (so-called PS plates) that use diazonium compounds, electrophotographic lithographic printing plates that use zinc oxide or organic photoconductors,
Lithographic printing plates based on silver salt photography using silver halide emulsions as photosensitive components are known, and a wide variety of inks are also known for use in printing with such lithographic printing plates. . However, with conventional printing inks, even if good prints can be obtained when using a specific printing plate or dampening solution, the type and printing conditions may change. This causes various drawbacks,
In some cases, it may not be possible to use it at all. It goes without saying that the properties required of such printing ink are that a sufficient amount of ink adheres to the printed areas and that no ink adheres to non-printed areas. Furthermore, it is necessary to consider fluidity, interfacial suitability, drying properties, etc. Particularly in planographic printing, oil-based ink and water are repeatedly supplied to the plate surface for each printing page during the printing of thousands to tens of thousands of sheets, so the interfacial tension and surface tension between the oil-based ink and water If it doesn't have the right balance,
An oil-based ink with excellent interfacial suitability is required because the image area gradually expands or disappears, emulsification of the ink occurs, and background smearing occurs.

。! JP-A No. 61-138677 describes a lithographic printing ink additive comprising a compound having an alkylene oxide unit and having an HLB value of 3 to 13. It is true that the compound shown in this patent can provide good interfacial properties to the ink and prevent background smearing, but depending on the type of lithographic printing material, ink, fountain solution, Ink I11 machine, etc. could still not be said to be sufficient. For example, when a silver salt printing plate with poor water retention is subjected to high-speed off-wheel printing, significant scumming occurs, and although the compound described in the above patent can be added to the ink to reduce scumming, the effect is not sufficient. On the other hand, various plate surface treatment solutions that follow the development of such silver salt lithographic printing plates contain colloidal silica with an average particle diameter of 0.
It is well known to use fine particles of 1 micron (μ) or less. For example, the dampening liquid of JP-A No. 48-45305,
Neutralizing liquid of JP-A-54-83502, patent application 1988-104
176 neutralizing liquid, desensitizing liquid, moisturizing liquid, Special Publication 1976-2
9001 fixing agent (liquid), dampening liquid, and other plate surface processing liquids. However, it is generally believed that inorganic fine particles such as colloidal silica and colloidal alumina adsorb to the surface of the lithographic printing plate, create a hydrophilic layer on the surface of the printing plate, and improve hydrophilicity. However, not only has it not been possible to fully achieve the most desired objective of preventing stains caused by printing ink, but it also has the serious drawback of inhibiting the spread of ink in one image area.
従って、本来的にはこのような無機微粒子を使用しなく
ても地汚れを生じることがない技術の開発が求められて
いる。Therefore, there is a need to develop a technique that does not cause scumming even without the use of such inorganic fine particles.

同じ結果が得られた。(However, the Dahlgren dampening device, which is a continuous water supply dampening device, was completely unable to feed water with a dampening solution containing 15% IPA.) Example 1 was repeated. However, the compound of the present invention and the comparative compound were The same result as in Example 1 was obtained by kneading with a quantity of rosin-modified alkylphenol resin as an ink additive.

な印刷物であった。Example 4 Example 1 was repeated. However, a commercially available PS plate was used. The blank ink and the ink containing the comparative compound caused slight background smearing, but the ink containing the ink additive of the present invention did not produce any background smearing, resulting in good printed matter with high ink density.

刷物を得ることもできる。(F) Effects of the Invention The ink additive of the present invention can extremely effectively prevent background smearing even in off-wheel inks and plate materials that are prone to smearing.
Good printed matter with high ink density can be obtained. Further, since inorganic fine particles such as colloidal silica are not necessarily required in the plate treatment liquid, printed matter with higher ink concentration can also be obtained.
