刷が困難になる。[Prior art] Printing with desensitizing ink for pressure-sensitive copying paper is currently carried out using the letterpress printing method,
It is performed using intaglio printing, planographic printing, and stencil printing. However, the breakdown is that the conventionally mainstream letterpress printing method and intaglio printing method are now shifting to the lithographic printing method. The reasons for this are that compared to letterpress printing, lithographic printing is easier to make plates, has higher dimensional accuracy, and because the printing pressure is lower, the coloring microcapsules coated on the back side of pressure-sensitive copy paper may be destroyed. These include the fact that there is no need for printing, and the print quality is excellent. However, since many of the pigments and desensitizers contained in desensitizing inks are hydrophilic,
It has a high affinity with the dampening water used in wet lithographic printing, and as a result, the ink emulsifies with the dampening water during printing, and background smudges occur, making printing difficult.
この様な問題を無くすために減感インキの改良かなされ
ているが未だ完全なものは得られていない。In order to eliminate such problems, improvements have been made to desensitizing inks, but nothing perfect has yet been achieved.

ことは出来ない。On the other hand, waterless lithographic printing without using dampening water is considered as a method to improve such problems, but a desensitizing ink for waterless lithographic printing has not yet been developed. Here, the conventional P
If desensitized ink for S is used as it is in waterless lithographic printing, there is no ink repellency with the non-image area of the plate, so problems such as background smearing and paper curling occur frequently, making it impossible to print. .
［発明が解決しようとする課題］
本発明は、かかる従来技術の諸欠点に鑑み創案されたも

The object of the present invention is to obtain a desensitized ink for lithographic printing.
［課題を解決するための手段］
かかる本発明の目的は、減感剤、充填剤およびベヒクル

ある水なし平版印刷用減感インキにより達成される。[Means for Solving the Problems] The objects of the present invention are achieved by a desensitizing ink for waterless lithographic printing which mainly consists of a desensitizer, a filler and a vehicle and has a viscosity of 500 poise or more.

添加することによって使用可能となる。A more preferable viscosity of the ink is 500 to 4000 voids; if the viscosity is less than 500 voids, the ink will have poor stain resistance and cannot be used for waterless lithographic printing. On the other hand, if the viscosity of the ink is extremely high, although the stain resistance is good, the paper may wrap around the plunket cylinder during printing, making the ink somewhat difficult to use in terms of paper suitability. However, even such ink can be used by adding a diluting reducer or tack remover.

1,000 copies were printed by adding 0.5% of D-400 (manufactured by Ingredients Burnish). During this time, it was visually checked to see if background smearing had occurred in the non-image area due to poor ink repulsion, and this was used as an evaluation of the background smudge resistance. Also, during this printing (a solid image with a pattern area ratio of 30%), it was checked whether any trouble occurred in which the printing paper was wrapped around the blanket cylinder, and this was determined as paper suitability. Furthermore, desensitization characteristics were checked by overlapping paper B on printed paper 0 and printing with a typewriter, and checking the state of color development.

A homogeneous solution is obtained by stirring in an oil bath at 240'C for 30 minutes. Next, the temperature of this solution was lowered to 150°C, 1% by weight of polyamide amine ("Persamide" 125, manufactured by Henkel Hakusuisha) was added, and after stirring in this state for 30 minutes, 4 moles of polypropylene glycol ethylene oxide was added. 1/6 oleic acid ester compound of the terminal OH group of the product 4
